Pregnant Dog Care: Nutrition, Whelping, and Postnatal Support

This article provides dog breeders and owners with evidence-informed guidance on managing a pregnant dog through gestation, whelping, and the postnatal period. The content covers nutritional adjustments during pregnancy, recognition of labor stages, preparation of whelping supplies, the whelping process itself, and care for the dam and her puppies after birth. Clear criteria for when to consult a veterinarian are included throughout. This information is for educational purposes and does not replace professional veterinary advice.

At a Glance: Key Management Decisions for Pregnant Dog Care

The table below summarizes critical decision points during a dog's pregnancy and early postpartum period. Each row links to detailed sections within this article.

Understanding Dog Pregnancy: Gestation Timeline and Physiological Changes

A dog's pregnancy, or gestation, typically lasts between 57 and 65 days from the day of ovulation, with an average of 63 days. The exact duration can vary by breed and individual. Accurate dating is important for predicting the whelping date and preparing supplies. Breeders should record the breeding dates and, if possible, confirm pregnancy through veterinary examination. The Merck Veterinary Manual provides reference information on canine reproduction and gestation timelines.

During the first few weeks of pregnancy, the dam may show no outward signs. Around week 3 to 4, some dogs experience a mild decrease in appetite or occasional vomiting, similar to morning sickness. By week 4, a veterinarian can often palpate the developing fetuses. Ultrasound can detect heartbeats as early as day 25 to 28. X-rays after day 45 can confirm the number of puppies, which helps the breeder know when labor is complete.

As pregnancy progresses, the dam's abdomen enlarges, and her mammary glands begin to develop. By week 6 to 7, the nipples become more prominent, and a clear discharge may appear. The dam's energy levels may decrease, and she may seek more rest. Breeders should provide a quiet, comfortable environment and avoid stressful situations. The AVMA provides resources for pet owners on recognizing signs of illness and when to seek veterinary care.

The final three weeks of gestation are a period of rapid fetal growth. The dam's nutritional needs increase significantly during this time. Her body weight may increase by 20 to 50 percent depending on litter size. Breeders should monitor the dam's body condition score and adjust feedings accordingly. Overweight dams are at higher risk for difficult labor, while underweight dams may produce weak puppies.

Nutrition for the Pregnant Dog: Feeding for Optimal Fetal Development

Proper nutrition is one of the most important factors in a successful pregnancy. The dam's diet directly affects fetal growth, birth weight, and the health of the puppies after birth. Nutritional management should be adjusted based on the stage of pregnancy.

Pre-Breeding and Early Pregnancy Nutrition

Before breeding, the dam should be in good body condition, neither underweight nor overweight. A high-quality adult maintenance diet is appropriate during the first three to four weeks of gestation. The dam's energy requirements do not increase significantly during this period. Overfeeding can lead to excessive weight gain, which complicates labor.

Breeders should continue feeding the dam her regular adult maintenance food until approximately week 4 of gestation. The diet should be complete and balanced, meeting the standards set by the Association of American Feed Control Officials (AAFCO). The dam should have access to fresh, clean water at all times.

Mid to Late Pregnancy Nutrition

Around week 4 of gestation, the dam's energy requirements begin to increase. By week 6 to 7, her energy needs may be 30 to 60 percent higher than maintenance levels. To meet these demands without overloading the digestive system, breeders should gradually transition the dam to a high-quality puppy food or a diet formulated for gestation and lactation. Puppy foods are energy-dense and contain higher levels of protein, fat, calcium, and phosphorus, which support fetal growth and milk production.

The transition to puppy food should be done gradually over 5 to 7 days to avoid digestive upset. Start by mixing 25 percent puppy food with 75 percent adult food, then increase the proportion every two days. By the end of the transition, the dam should be eating 100 percent puppy food.

During the last three weeks of pregnancy, the dam's appetite may decrease as the growing puppies take up space in her abdomen. To maintain calorie intake, offer smaller, more frequent meals throughout the day. Some breeders feed three to four meals daily during this period. The dam should always have access to food, but intake should be monitored to prevent obesity.

Calcium and Mineral Considerations

Calcium is critical for fetal skeletal development and for preventing eclampsia (milk fever) after birth. However, excessive calcium supplementation during pregnancy can disrupt the dam's calcium regulation and actually increase the risk of eclampsia. The dam should receive adequate calcium from her diet, not from supplements. High-quality puppy foods contain appropriate levels of calcium and phosphorus for pregnant and lactating dogs.

Breeders should not add calcium supplements to the dam's diet unless specifically directed by a veterinarian. Over-supplementation can lead to serious health problems for both the dam and the puppies. If the dam is eating a complete and balanced puppy food, additional supplementation is unnecessary.

Water Intake

The dam's water requirements increase during pregnancy, especially in the final weeks and during lactation. Fresh, clean water should be available at all times. Breeders should monitor water intake and ensure the dam is drinking adequately. Dehydration can reduce milk production and affect the health of the puppies.

Whelping Supplies: Preparing for the Birth

Proper preparation for whelping reduces stress for both the dam and the breeder. Supplies should be assembled at least one week before the due date. Having everything ready in advance allows the breeder to focus on the dam during labor.

The Whelping Box

The whelping box should be large enough for the dam to stretch out comfortably with room for the puppies. It should have sides high enough to contain the puppies but low enough for the dam to enter and exit easily. A rail or ledge around the inside of the box, about 4 to 6 inches from the floor, helps prevent the dam from accidentally crushing puppies against the sides.

The box should be placed in a quiet, draft-free area of the home, away from heavy traffic and other pets. The temperature in the whelping area should be maintained at 75 to 80 degrees Fahrenheit (24 to 27 degrees Celsius) for the first week after birth. A heat lamp or heating pad placed under one side of the box allows the dam to move away from the heat if she becomes too warm.

Bedding and Cleaning Supplies

The whelping box should be lined with clean, absorbent bedding. Newspaper is commonly used because it is easy to replace and allows the breeder to monitor discharge. After the puppies are born, the bedding should be changed to soft towels or fleece blankets that provide traction for the puppies. Avoid materials that can snag claws or be ingested.

Cleaning supplies should include:

• Disposable gloves
• Paper towels
• Antiseptic solution (such as chlorhexidine) for cleaning the umbilical area
• Trash bags for soiled bedding

Whelping Kit

A whelping kit should contain the following items:

• Clean towels for drying puppies
• Dental floss or unwaxed thread for tying umbilical cords
• Sterile scissors for cutting umbilical cords
• Iodine or chlorhexidine solution for disinfecting umbilical stumps
• Bulb syringe for clearing airways
• Heating pad or hot water bottle for warming puppies
• Kitchen scale for weighing puppies
• Notebook and pen for recording birth details
• Emergency contact numbers for the veterinarian

Emergency Supplies

Breeders should have a plan for veterinary emergencies. Keep the veterinarian's phone number and the number of the nearest 24-hour emergency clinic readily available. If the dam has a known risk factor for difficult labor, such as a narrow pelvic canal or a history of dystocia, discuss a plan with the veterinarian before the due date.

Recognizing the Signs of Labor: Stage 1

Labor in dogs occurs in three stages. Recognizing the signs of each stage helps the breeder provide appropriate support and know when to intervene.

Stage 1 Labor: Preparation

Stage 1 labor typically lasts 6 to 12 hours, but can extend to 24 hours in some dogs, especially first-time mothers. During this stage, the dam's cervix dilates and uterine contractions begin. The dam may appear restless, pace, pant, shiver, or seek seclusion. She may refuse food and may vomit. Nesting behavior is common, the dam may tear up bedding or rearrange the whelping box.

Breeders should observe the dam quietly without disturbing her. Provide a calm environment and allow her to settle in the whelping box. Do not offer food during stage 1, as the dam may vomit. Water should be available.

Stage 1 ends when the dam begins active straining, which marks the transition to stage 2 labor. If the dam has not progressed to stage 2 within 24 hours of the onset of stage 1 signs, consult a veterinarian.

The Whelping Process: Stage 2 and Stage 3

Stage 2 Labor: Delivery of Puppies

Stage 2 labor is characterized by strong, visible abdominal contractions that result in the delivery of a puppy. The dam may strain, grunt, or cry out. The first puppy should be delivered within 2 to 4 hours of the onset of active straining. If the dam strains for more than 2 hours without producing a puppy, veterinary assistance is needed.

Each puppy is born enclosed in a fetal membrane (amniotic sac). The dam typically breaks the sac, cleans the puppy, and severs the umbilical cord by chewing it. If the dam does not break the sac within 1 to 2 minutes, the breeder must intervene. Use a clean towel to gently tear the sac away from the puppy's face and clear the mouth and nose of fluid. Rub the puppy vigorously with a towel to stimulate breathing.

The umbilical cord should be clamped or tied about 1 inch from the puppy's body and cut with sterile scissors. Apply iodine or chlorhexidine solution to the stump to prevent infection. The puppy should be placed with the dam to nurse as soon as it is breathing steadily.

The interval between puppies varies. Most dogs deliver a puppy every 30 to 60 minutes, but intervals of up to 2 hours can be normal. If more than 4 hours pass between puppies, or if the dam appears distressed, contact a veterinarian.

Stage 3 Labor: Delivery of Placentas

Stage 3 labor involves the expulsion of the placenta (afterbirth) for each puppy. Placentas are usually delivered within 5 to 15 minutes after each puppy. The dam may eat the placentas, which is normal behavior. However, eating too many placentas can cause digestive upset. Breeders should count the placentas to ensure one is delivered for each puppy. A retained placenta can cause infection and requires veterinary attention.

The dam may alternate between stage 2 and stage 3, delivering a puppy followed by a placenta, then another puppy. The entire whelping process can take 6 to 12 hours, but may be longer for large litters.

When to Call the Veterinarian During Whelping

Breeders should contact a veterinarian immediately if any of the following occur:

• The dam has been in stage 1 labor for more than 24 hours without progressing to stage 2
• The dam strains for more than 2 hours without delivering a puppy
• More than 4 hours pass between puppies
• Green or dark discharge is present without a puppy being delivered within 30 minutes
• The dam appears weak, collapses, or shows signs of severe pain
• A puppy is partially visible but not delivered after 15 minutes of straining
• The dam has not delivered all puppies within 24 hours of the start of stage 2

Postnatal Care for the Dam: Recovery and Lactation

After all puppies are delivered, the dam enters the postnatal period. Her body undergoes significant changes as she recovers from birth and begins lactation. Proper care during this time supports her health and the health of the puppies.

Immediate Post-Whelping Care

After whelping, the dam should be offered fresh water and a small meal. She may be tired and hungry. Provide a quiet, clean environment. The whelping box should be cleaned of soiled bedding and replaced with clean, soft material.

Monitor the dam for signs of excessive bleeding. A small amount of dark discharge (lochia) is normal for up to three weeks after birth. However, bright red blood or large clots indicate hemorrhage and require immediate veterinary attention.

The dam's temperature should be monitored daily for the first week. A normal temperature is 100 to 102.5 degrees Fahrenheit (37.8 to 39.2 degrees Celsius). A temperature above 103 degrees Fahrenheit (39.4 degrees Celsius) may indicate infection (metritis) and requires veterinary evaluation.

Nutrition for the Lactating Dam

Lactation places high energy demands on the dam. Her calorie requirements may increase to two to four times her maintenance needs, depending on litter size. Continue feeding the high-quality puppy food that was started during pregnancy. The dam should have free access to food at all times. Many breeders feed three to four meals daily to ensure adequate intake.

Water is critical for milk production. The dam should have constant access to fresh, clean water. Some breeders add water to the dam's food to increase fluid intake.

Calcium requirements are high during lactation. The dam should receive adequate calcium from her diet. If the dam shows signs of eclampsia (muscle tremors, restlessness, stiff gait, or seizures), this is a medical emergency. Eclampsia is caused by low blood calcium and requires immediate veterinary treatment. Do not give oral calcium supplements without veterinary guidance, as this can worsen the condition.

Monitoring the Dam for Health Problems

Breeders should observe the dam daily for signs of illness. Common postnatal problems include:

• Metritis: Infection of the uterus, characterized by fever, foul-smelling discharge, lethargy, and loss of appetite
• Mastitis: Infection of the mammary glands, characterized by hot, swollen, painful glands and fever
• Eclampsia: Low blood calcium, characterized by muscle tremors, restlessness, panting, and seizures
• Retained placenta: Failure to pass all placentas, which can cause infection

Any of these conditions require veterinary attention. Early intervention improves outcomes.

Postnatal Care for Puppies: First 24 Hours and Beyond

The first 24 hours after birth are critical for puppy survival. Breeders should monitor each puppy closely and intervene when necessary.

Immediate Care After Birth

After each puppy is born, ensure it is breathing normally. Clear the airways with a bulb syringe if needed. Rub the puppy vigorously with a towel to stimulate breathing and circulation. The puppy should be placed with the dam to nurse as soon as it is active.

Puppies should nurse within 2 hours of birth. The first milk, colostrum, is rich in antibodies that provide passive immunity. Puppies must receive colostrum within the first 12 to 24 hours of life to absorb these antibodies. If a puppy is too weak to nurse, consult a veterinarian about alternative feeding.

Weighing and Monitoring Puppies

Puppies should be weighed at birth and daily for the first two weeks. A kitchen scale that measures in grams provides accurate readings. Record each puppy's weight in a notebook. Healthy puppies should gain weight steadily, typically 5 to 10 percent of their birth weight daily. A puppy that fails to gain weight or loses weight requires veterinary evaluation.

Other signs of a healthy puppy include:

• Steady weight gain
• Active and vocal
• Warm to the touch
• Nursing vigorously
• Pink mucous membranes

Signs of a sick puppy include:

• Weight loss or failure to gain weight
• Weakness or lethargy
• Excessive crying
• Cold to the touch
• Blue or pale mucous membranes
• Diarrhea or vomiting

Temperature Regulation

Newborn puppies cannot regulate their body temperature for the first two weeks of life. They rely on the dam and the environment for warmth. The whelping area should be maintained at 75 to 80 degrees Fahrenheit (24 to 27 degrees Celsius) for the first week. A heat lamp or heating pad placed under one side of the box provides a warm zone. Puppies should be able to move away from the heat source if they become too warm.

Hypothermia is a common cause of puppy death. Signs include cold skin, lethargy, and failure to nurse. If a puppy feels cold, warm it gradually by placing it against the dam's belly or using a warm water bottle wrapped in a towel. Do not use a microwave to warm puppies, as this can cause burns.

Umbilical Cord Care

The umbilical stump should be kept clean and dry. Apply iodine or chlorhexidine solution to the stump at birth and again daily for the first few days. The stump typically dries and falls off within 3 to 5 days. Signs of infection include redness, swelling, discharge, or a foul odor. An infected umbilical stump requires veterinary attention.

Common Failure Patterns in Pregnant Dog Care

Despite careful management, problems can arise during pregnancy, whelping, and the postnatal period. Recognizing common failure patterns helps breeders take corrective action quickly.

Failure Pattern 1: Inadequate Nutrition During Pregnancy

Some breeders continue feeding adult maintenance food throughout pregnancy, failing to increase energy and nutrient intake during the last three weeks. This can result in low birth weight puppies, poor milk production, and weak puppies. The dam may lose body condition and have difficulty lactating.

Prevention: Transition to a high-quality puppy food around week 4 of gestation. Increase meal frequency during the last three weeks. Monitor the dam's body condition and adjust feedings as needed.

Failure Pattern 2: Delayed Veterinary Intervention During Dystocia

Breeders may wait too long to seek veterinary help when labor is not progressing. Prolonged labor can cause fetal distress, stillbirth, and uterine rupture. The dam may become exhausted and unable to deliver remaining puppies.

Prevention: Know the normal timelines for each stage of labor. Contact a veterinarian if the dam strains for more than 2 hours without delivering a puppy, if more than 4 hours pass between puppies, or if the dam shows signs of distress.

Failure Pattern 3: Inadequate Whelping Preparation

Breeders who do not assemble whelping supplies in advance may find themselves unprepared when labor begins. This can lead to unsanitary conditions, delayed intervention, and increased stress for the dam.

Prevention: Assemble the whelping kit and set up the whelping box at least one week before the due date. Have emergency contact numbers readily available.

Failure Pattern 4: Failure to Monitor Puppies Closely

Some breeders do not weigh puppies daily or observe them for signs of illness. Sick puppies can deteriorate rapidly, and early intervention is critical for survival.

Prevention: Weigh puppies at birth and daily for the first two weeks. Observe each puppy for nursing behavior, activity level, and body temperature. Seek veterinary care for any puppy that fails to gain weight or shows signs of illness.

Failure Pattern 5: Over-Supplementation of Calcium

Breeders may add calcium supplements to the dam's diet during pregnancy or lactation, believing this prevents eclampsia. In fact, excessive calcium during pregnancy can disrupt the dam's calcium regulation and increase the risk of eclampsia after birth.

Prevention: Feed a complete and balanced puppy food that meets AAFCO standards. Do not add calcium supplements unless specifically directed by a veterinarian.

Records and Measurements for Pregnant Dog Care

Accurate record-keeping helps breeders track the dam's health, monitor puppy development, and identify problems early. The following records should be maintained.

Breeding and Pregnancy Records

Record the following information:

• Breeding dates and method (natural or artificial insemination)
• Confirmation of pregnancy (veterinary examination, ultrasound, or X-ray)
• Estimated due date (based on 63 days from ovulation)
• Dam's weight at breeding and at weekly intervals during pregnancy
• Dam's body condition score at each check

Whelping Records

During whelping, record:

• Time of onset of stage 1 labor
• Time of onset of stage 2 labor (active straining)
• Time of birth for each puppy
• Sex of each puppy
• Birth weight of each puppy
• Color and markings of each puppy
• Time of delivery of each placenta
• Any complications or interventions

Postnatal Records

After whelping, record:

• Daily weight of each puppy for the first two weeks
• Dam's temperature daily for the first week
• Dam's appetite and water intake
• Dam's behavior and attitude
• Any signs of illness in the dam or puppies
• Veterinary visits and treatments

Welfare and Safety Context for Pregnant Dog Care

The welfare of the dam and her puppies is the primary concern throughout pregnancy, whelping, and the postnatal period. Breeders have a responsibility to provide appropriate care and to seek veterinary assistance when needed. The World Organisation for Animal Health provides standards and guidelines for animal welfare that inform responsible breeding practices.

Stress Reduction

Stress can negatively affect the dam's health and the development of the puppies. Minimize stress by providing a quiet, comfortable environment. Avoid loud noises, excessive handling, and the presence of unfamiliar people or animals. The dam should have a private area where she can rest undisturbed.

Pain Management

Whelping is a painful process. The dam may show signs of pain, such as panting, restlessness, and vocalization. While some discomfort is normal, severe pain requires veterinary evaluation. Do not give the dam any pain medications unless prescribed by a veterinarian, as many human pain relievers are toxic to dogs.

Hygiene and Infection Control

Cleanliness reduces the risk of infection for both the dam and the puppies. The whelping box should be cleaned daily and bedding changed as needed. The dam's mammary glands should be kept clean. Wash hands before handling puppies, especially if other animals are present.

Ethical Considerations

Breeders should only breed dogs that are healthy and free from genetic disorders that could affect the puppies. The dam should be old enough to breed safely but not past her prime reproductive years. Responsible breeders plan for the care of the puppies until they are placed in new homes.

Professional Escalation Criteria: When to Consult a Veterinarian

Breeders should have a low threshold for consulting a veterinarian during pregnancy, whelping, and the postnatal period. The following situations require veterinary attention.

During Pregnancy

• The dam shows signs of illness, such as vomiting, diarrhea, or lethargy
• The dam has a vaginal discharge that is green, yellow, or bloody
• The dam has not gained weight or has lost weight during pregnancy
• The dam is not eating or drinking
• The dam has a temperature above 103 degrees Fahrenheit (39.4 degrees Celsius)
• The dam appears to be in pain

During Whelping

• Stage 1 labor lasts more than 24 hours without progression to stage 2
• The dam strains for more than 2 hours without delivering a puppy
• More than 4 hours pass between puppies
• Green or dark discharge is present without a puppy being delivered within 30 minutes
• The dam appears weak, collapses, or shows signs of severe pain
• A puppy is partially visible but not delivered after 15 minutes of straining
• The dam has not delivered all puppies within 24 hours of the start of stage 2

After Whelping

• The dam has a temperature above 103 degrees Fahrenheit (39.4 degrees Celsius)
• The dam has a foul-smelling vaginal discharge
• The dam is not eating or drinking
• The dam shows signs of eclampsia (muscle tremors, restlessness, stiff gait, seizures)
• The dam has hot, swollen, painful mammary glands
• The dam is not producing milk
• A puppy fails to gain weight or loses weight
• A puppy is weak, lethargic, or cries excessively
• A puppy has diarrhea or vomiting
• A puppy has an infected umbilical stump

Decision Framework for Whelping Intervention: A Structured Approach to Knowing When to Act

Deciding when to intervene during a dog's labor is one of the most challenging aspects of managing a whelping. Breeders often struggle with the balance between allowing normal progress and recognizing when veterinary assistance is needed. A structured decision framework helps remove guesswork and provides clear criteria for action. This framework is based on established veterinary guidelines and should be reviewed with your veterinarian before the due date.

The 2-4-6 Rule for Whelping Progress

The 2-4-6 rule provides a simple memory aid for monitoring labor progression. This framework helps breeders track three critical time points during stage 2 labor.

2 Hours of Active Straining Without a Puppy

Once the dam begins active, visible abdominal contractions (stage 2 labor), she should deliver a puppy within 2 hours. Active straining is distinct from the restlessness and panting of stage 1. If the dam strains forcefully for 2 hours without producing a puppy, this constitutes dystocia (difficult labor) and requires immediate veterinary evaluation. The Merck Veterinary Manual provides reference information on canine dystocia and its management.

4 Hours Between Puppies

After the first puppy is delivered, the interval between subsequent puppies should not exceed 4 hours. While intervals of 30 to 60 minutes are typical, some normal deliveries may have gaps of up to 2 hours. If 4 hours pass without another puppy and the dam has not delivered all placentas, veterinary assessment is needed. This rule applies regardless of whether the dam appears comfortable between contractions.

6 Puppies or 6 Hours Total Active Labor

For small litters (fewer than 6 puppies), the entire stage 2 labor should be complete within 6 hours of the first puppy's birth. For larger litters, the breeder should expect delivery of approximately one puppy per hour on average. If the dam has not completed delivery within 6 hours of active labor onset, or if she appears exhausted, consult a veterinarian.

The Green Discharge Decision Point

Green or dark green vaginal discharge during labor indicates that a placenta has separated from the uterine wall. This discharge is normal when it appears immediately before or after a puppy is delivered. However, if green discharge is present without a puppy being delivered within 30 minutes, this signals that a puppy may be stuck or that the placenta has detached prematurely. This situation requires veterinary attention. The AVMA provides resources for pet owners on recognizing signs of illness and when to seek veterinary care.

The Partially Visible Puppy Protocol

If a puppy is partially visible at the vulva but not delivered after 15 minutes of active straining, intervention is needed. The breeder should not attempt to pull the puppy without veterinary guidance, as improper traction can injure the puppy or the dam. Gently lubricate the area with sterile lubricant if available, and contact the veterinarian immediately. If the puppy's membranes are intact and the head is visible, the breeder may carefully clear the membranes from the nose and mouth while waiting for veterinary assistance.

The Exhaustion Assessment

A dam that appears exhausted, collapses between contractions, or shows signs of shock (pale gums, weak pulse, rapid breathing) requires emergency veterinary care. Exhaustion can prevent the dam from delivering remaining puppies and may indicate underlying problems such as uterine inertia or hemorrhage. Breeders should monitor the dam's energy level throughout labor and provide rest periods between puppies. Offer water between deliveries, but do not force the dam to eat during active labor.

The Placenta Count Verification

After all puppies are delivered, the breeder must count the placentas. The number of placentas should equal the number of puppies. If a placenta is missing, it may be retained in the uterus. Retained placentas can cause metritis (uterine infection) and require veterinary treatment. The dam may pass retained placentas within 24 hours of whelping, but if she develops fever, foul-smelling discharge, or lethargy, veterinary evaluation is needed. The World Organisation for Animal Health provides standards and guidelines for animal welfare that inform responsible breeding practices.

The Post-Whelping Temperature Monitoring Protocol

After whelping, the dam's temperature should be monitored daily for the first week. A normal temperature is 100 to 102.5 degrees Fahrenheit (37.8 to 39.2 degrees Celsius). A temperature above 103 degrees Fahrenheit (39.4 degrees Celsius) may indicate metritis or mastitis and requires veterinary evaluation. A temperature below 99 degrees Fahrenheit (37.2 degrees Celsius) may indicate hypothermia or shock. Record the dam's temperature at the same time each day, preferably in the morning before she eats or becomes active.

The Puppy Vigor Assessment

Each puppy should be assessed for vigor immediately after birth. A vigorous puppy will cry, move actively, and attempt to nurse within 30 minutes. A weak puppy may be quiet, limp, or slow to respond. The APGAR score, adapted from human medicine, can be used to assess puppy vitality. The score evaluates five parameters: heart rate, respiratory effort, muscle tone, reflex irritability, and mucous membrane color. Each parameter is scored 0, 1, or 2, with a maximum score of 10. Puppies with scores below 7 may require resuscitation or veterinary attention. Breeders should discuss the APGAR scoring system with their veterinarian before the due date.

The Weight Gain Threshold

Puppies should gain weight steadily from birth. A puppy that loses weight or fails to gain weight for 24 hours requires veterinary evaluation. The minimum acceptable weight gain is 5 percent of birth weight per day. For example, a 400-gram puppy should gain at least 20 grams daily. Weigh puppies at the same time each day, using the same scale, and record weights in a notebook. If a puppy's weight plateaus or drops, check for nursing difficulties, hypothermia, or illness. The AAHA provides resources for veterinary care standards that inform puppy health monitoring.

The Eclampsia Recognition Checklist

Eclampsia (milk fever) is a life-threatening emergency that requires immediate veterinary treatment. Breeders should recognize the early signs and act quickly. The checklist includes:

• Muscle tremors or twitching, especially around the face and ears
• Restlessness, pacing, or panting
• Stiff gait or difficulty walking
• Drooling or excessive salivation
• Dilated pupils
• Disorientation or confusion
• Seizures or collapse

If any of these signs appear, contact a veterinarian immediately. Do not give oral calcium supplements, as this can worsen the condition. The dam needs intravenous calcium administered by a veterinarian. The Merck Veterinary Manual provides reference information on eclampsia and its treatment.

The Mastitis Detection Protocol

Mastitis (mammary gland infection) can develop rapidly and affect the dam's health and milk production. Breeders should examine the dam's mammary glands daily for the first two weeks after whelping. Signs of mastitis include:

• Hot, swollen, or painful mammary glands
• Redness or discoloration of the skin over the gland
• Hard or firm areas within the gland
• Discharge from the nipple that is bloody, pus-like, or discolored
• Fever, lethargy, or loss of appetite in the dam

If mastitis is suspected, the affected gland should not be used for nursing until evaluated by a veterinarian. Puppies may need supplemental feeding if the dam's milk production is reduced. The AVMA provides resources for pet owners on recognizing signs of illness and when to seek veterinary care.

The Metritis Warning Signs

Metritis (uterine infection) typically occurs within the first week after whelping. Breeders should monitor the dam for:

• Fever above 103 degrees Fahrenheit (39.4 degrees Celsius)
• Foul-smelling vaginal discharge that is brown, green, or bloody
• Lethargy, depression, or loss of appetite
• Neglect of puppies or refusal to nurse
• Decreased milk production

Metritis requires veterinary treatment with antibiotics and supportive care. The dam may need to be separated from puppies temporarily if she is severely ill. Puppies may require supplemental feeding during treatment. The AAHA provides resources for veterinary care standards that inform postnatal health monitoring.

The Puppy Hypothermia Response

Newborn puppies cannot regulate their body temperature for the first two weeks of life. Hypothermia is a common cause of puppy death. If a puppy feels cold to the touch, is lethargic, or fails to nurse, take immediate action:

• Warm the puppy gradually by placing it against the dam's belly
• Use a warm water bottle wrapped in a towel, placed next to the puppy
• Set the whelping box temperature to 85 to 90 degrees Fahrenheit (29 to 32 degrees Celsius) for hypothermic puppies
• Do not use a microwave to warm puppies, as this can cause burns
• Do not feed a cold puppy, as the digestive system may not function properly

Once the puppy is warm and active, offer it to the dam to nurse. If the puppy does not improve within 30 minutes, consult a veterinarian. The World Organisation for Animal Health provides standards and guidelines for animal welfare that inform neonatal care practices.

Frequently Asked Questions

How long is a dog pregnant?

A dog's pregnancy typically lasts between 57 and 65 days from the day of ovulation, with an average of 63 days. The exact duration can vary by breed and individual. Accurate dating based on breeding records and veterinary examination helps predict the due date.

What should I feed my pregnant dog?

During the first four weeks of pregnancy, feed a high-quality adult maintenance diet. Around week 4, gradually transition to a high-quality puppy food that is energy-dense and contains higher levels of protein, fat, calcium, and phosphorus. Continue feeding puppy food through lactation. Offer smaller, more frequent meals during the last three weeks of pregnancy.

How do I know when my dog is in labor?

Signs of stage 1 labor include restlessness, panting, shivering, nesting behavior, and refusal of food. The dam may seek seclusion and appear anxious. Stage 1 typically lasts 6 to 12 hours. Stage 2 labor begins with strong abdominal contractions that result in the delivery of puppies.

What supplies do I need for whelping?

Essential supplies include a whelping box with clean bedding, clean towels, dental floss or thread for tying umbilical cords, sterile scissors, iodine or chlorhexidine solution, a bulb syringe, a heating pad or heat lamp, a kitchen scale, a notebook for records, and emergency contact numbers for the veterinarian.

When should I call the veterinarian during whelping?

Call the veterinarian if the dam has been in stage 1 labor for more than 24 hours, strains for more than 2 hours without delivering a puppy, has more than 4 hours between puppies, has green discharge without a puppy, appears weak or in severe pain, or has not delivered all puppies within 24 hours of the start of stage 2.

How do I care for newborn puppies?

Ensure each puppy is breathing and nursing within 2 hours of birth. Weigh puppies at birth and daily for the first two weeks. Keep the whelping area warm (75 to 80 degrees Fahrenheit). Clean the umbilical stump with iodine or chlorhexidine. Monitor puppies for weight gain, activity, and signs of illness.

What is eclampsia in dogs?

Eclampsia, also called milk fever, is a life-threatening condition caused by low blood calcium in lactating dogs. Signs include muscle tremors, restlessness, panting, stiff gait, and seizures. Eclampsia requires immediate veterinary treatment. Do not give oral calcium supplements without veterinary guidance.

How long should puppies nurse?

Puppies should nurse exclusively for the first 3 to 4 weeks of life. Weaning typically begins around 3 to 4 weeks of age, when puppies can start eating soft food mixed with puppy formula or water. Complete weaning usually occurs by 6 to 8 weeks of age. The dam should have access to food and water throughout the nursing period.
