Puppy Preventive Care Schedule: Vaccinations, Deworming, and Wellness Exams

This article provides a month-by-month preventive care schedule for puppies from 6 weeks to 16 weeks of age and beyond. It covers core vaccinations, deworming protocols, heartworm prevention, and routine wellness examinations. The information is intended for new puppy owners who need a clear timeline for veterinary visits and health maintenance decisions. All recommendations are based on general veterinary guidelines. Individual protocols may vary by region, breed, and local disease prevalence. Always consult your veterinarian for a personalized schedule.

At a Glance: Puppy Preventive Care Timeline

The table below summarizes the typical schedule for core vaccinations, deworming, heartworm prevention, and wellness exams from 6 to 16 weeks of age. This is a general framework. Your veterinarian will adjust timing based on your puppy's specific needs and local risk factors.

Core Vaccinations: What They Protect Against

Core vaccines are recommended for all puppies regardless of lifestyle or geographic location. The American Veterinary Medical Association (AVMA) provides resources for pet owners on vaccine recommendations, which are based on current scientific evidence and disease risk assessment. The Merck Veterinary Manual also outlines standard vaccination protocols for dogs.

Distemper, Hepatitis, Parainfluenza, and Parvovirus (DHPP)

The DHPP combination vaccine protects against four serious viral diseases. Canine distemper virus attacks the respiratory, gastrointestinal, and nervous systems. Canine adenovirus type 1 causes infectious hepatitis, which affects the liver. Parainfluenza virus contributes to kennel cough complex. Canine parvovirus type 2 causes severe hemorrhagic gastroenteritis and is highly contagious, especially in young puppies.

Puppies receive their first DHPP dose at 6 to 8 weeks of age. Maternal antibodies from the mother's colostrum can interfere with vaccine response, so a series of boosters is necessary. The second dose is given at 10 to 12 weeks, and the third at 14 to 16 weeks. Some protocols include a fourth dose at 16 to 20 weeks for high-risk environments. The World Organisation for Animal Health (WOAH) provides international standards for vaccine efficacy and disease control.

Rabies Vaccination

Rabies is a fatal zoonotic disease that affects the central nervous system. Rabies vaccination is required by law in most jurisdictions. The first rabies vaccine is typically given at 12 to 16 weeks of age, depending on local regulations. A booster is given one year later, then every one to three years based on the vaccine type and local laws. The AVMA provides guidance on rabies vaccination schedules and legal requirements.

Non-Core Vaccinations

Non-core vaccines are recommended based on geographic location, lifestyle, and exposure risk. These may include leptospirosis, Bordetella bronchiseptica (kennel cough), canine influenza, and Lyme disease. Your veterinarian will assess your puppy's risk factors and recommend appropriate non-core vaccines. The Merck Veterinary Manual describes the indications and efficacy of these vaccines.

Deworming Schedule: Intestinal Parasite Control

Puppies are commonly infected with intestinal parasites such as roundworms (Toxocara canis) and hookworms (Ancylostoma caninum). These parasites can cause poor growth, diarrhea, anemia, and in severe cases, death. Some parasites are zoonotic, meaning they can be transmitted to humans, particularly children.

Initial Deworming Protocol

Puppies should receive their first deworming treatment at 2 to 3 weeks of age, before the first vaccination visit. Many breeders and shelters administer this initial treatment. The second deworming occurs at 5 to 6 weeks, and the third at 8 to 9 weeks. A fourth treatment at 12 weeks is common. The exact schedule depends on the product used and local parasite prevalence.

Fecal Examination

A fecal flotation test should be performed at each wellness visit to identify parasite eggs. This test allows your veterinarian to prescribe the most effective deworming medication for the specific parasites present. Some parasites, such as Giardia and coccidia, require different treatments than roundworms and hookworms. The Merck Veterinary Manual provides detailed information on parasite identification and treatment.

Ongoing Parasite Prevention

After the initial deworming series, most puppies transition to monthly heartworm prevention products that also control intestinal parasites. Many heartworm preventives contain medications that treat roundworms, hookworms, and whipworms. Your veterinarian will recommend a product based on your puppy's needs and local parasite risks.

Heartworm Prevention: Timing and Compliance

Heartworm disease is caused by Dirofilaria immitis, a parasitic worm transmitted by mosquitoes. The disease affects the heart, lungs, and blood vessels, and can be fatal if untreated. Prevention is far safer and more cost-effective than treatment.

When to Start Prevention

Heartworm prevention should begin as early as 6 to 8 weeks of age, depending on the product. Some products are labeled for use from 6 weeks, while others require the puppy to be 8 weeks or older. Your veterinarian will select an appropriate product and provide the first dose during the initial wellness visit.

Year-Round Prevention

The AVMA recommends year-round heartworm prevention for all dogs, even in colder climates where mosquitoes are less active. This is because mosquitoes can survive indoors and during mild winter periods. Consistent monthly administration is critical for effectiveness. Missing a dose can leave your puppy vulnerable to infection.

Testing Requirements

Puppies should be tested for heartworm infection before starting prevention if they are over 6 months of age. For puppies starting prevention at 6 to 8 weeks, the initial test is not required because the infection cannot be detected until at least 6 months after transmission. However, a test is recommended at 6 to 12 months of age to confirm the prevention program is working.

Wellness Examinations: What to Expect

A wellness examination is a comprehensive physical assessment performed by a veterinarian. These exams are essential for monitoring growth, detecting early signs of disease, and establishing a baseline for your puppy's health.

Components of a Wellness Exam

A thorough wellness exam includes the following components:

• Weight and body condition score assessment
• Temperature, pulse, and respiration rate
• Eye examination for discharge, redness, or abnormalities
• Ear examination for infection, mites, or debris
• Oral examination for dental development and gum health
• Heart and lung auscultation for murmurs or abnormal sounds
• Abdominal palpation for organ size and discomfort
• Skin and coat evaluation for parasites, lesions, or dryness
• Musculoskeletal assessment for joint health and gait
• Neurological evaluation for reflexes and coordination

Frequency of Exams

Puppies require more frequent wellness exams than adult dogs due to their rapid growth and vaccination schedule. The typical schedule includes exams at 6 to 8 weeks, 10 to 12 weeks, 14 to 16 weeks, and 16 to 20 weeks. After the initial series, annual wellness exams are recommended for adult dogs.

What to Bring to the Visit

Bring any medical records from the breeder or shelter, including vaccination history, deworming dates, and any previous test results. Also bring a fresh fecal sample (less than 12 hours old) for parasite testing. Write down any questions or concerns you have about your puppy's behavior, diet, or health.

Records and Measurements: Tracking Your Puppy's Health

Maintaining accurate health records is essential for monitoring your puppy's progress and ensuring timely preventive care. Records also provide valuable information for future veterinary visits and for breeders if applicable.

What to Record

Keep a log of the following information:

• Vaccination dates and types (including lot numbers if available)
• Deworming dates and products used
• Heartworm prevention dates and product names
• Wellness exam dates and findings
• Weight at each visit
• Fecal test results
• Any medications or supplements given
• Any health concerns or observations

How to Organize Records

Use a dedicated notebook, a digital spreadsheet, or a pet health app to organize your records. Many veterinary clinics provide a vaccination card or online portal where you can access your puppy's records. Keep copies of all records in a safe place, and bring them to each veterinary visit.

Using Records for Decision Making

Review your records regularly to ensure you are staying on schedule. If you miss a vaccination or deworming dose, contact your veterinarian for guidance on how to proceed. Records also help your veterinarian identify patterns, such as recurring ear infections or weight fluctuations, that may require further investigation.

Common Failure Patterns in Puppy Preventive Care

Despite best intentions, many puppy owners encounter challenges that disrupt the preventive care schedule. Recognizing these common failure patterns can help you avoid them.

Missed Vaccination Doses

Missing a vaccination dose is one of the most common failures. If a dose is delayed by more than a few days, the puppy may not be fully protected. In some cases, the series may need to be restarted. Contact your veterinarian immediately if you miss a scheduled vaccination.

Inconsistent Deworming

Some owners stop deworming after the initial series, thinking the puppy is parasite-free. However, puppies can be reinfected from the environment or from their mother. Continue deworming as recommended by your veterinarian, typically through monthly heartworm prevention that includes intestinal parasite control.

Skipping Wellness Exams

Wellness exams are sometimes skipped because the puppy appears healthy. However, many health problems are not visible to the untrained eye. A veterinarian can detect early signs of disease, such as heart murmurs, dental problems, or joint issues, before they become serious.

Delaying Heartworm Prevention

Some owners delay starting heartworm prevention or stop during winter months. This leaves the puppy vulnerable to infection. Heartworm disease is expensive and dangerous to treat, and prevention is simple and affordable. Administer prevention year-round as directed.

Not Following Up on Test Results

Fecal tests and other diagnostic tests may reveal issues that require treatment. If you do not follow up on abnormal results, your puppy may suffer from untreated infections or conditions. Always discuss test results with your veterinarian and complete any recommended treatments.

Welfare and Safety Context

Preventive care is about preventing disease and ensuring your puppy's overall welfare and safety. The World Organisation for Animal Health (WOAH) emphasizes the importance of animal health and welfare in its international standards.

Pain and Stress Reduction

Vaccinations and blood draws can cause temporary discomfort. Your veterinarian can use techniques to minimize pain and stress, such as gentle handling, distraction, and topical anesthetics. Discuss any concerns you have about your puppy's comfort during visits.

Zoonotic Disease Prevention

Some diseases that affect puppies can also be transmitted to humans. Roundworms and hookworms are zoonotic parasites that can cause serious illness in children. Rabies is a fatal zoonotic disease. By following the preventive care schedule, you protect both your puppy and your family.

Socialization and Behavior

Wellness exams provide an opportunity for your puppy to have positive experiences with veterinary staff. Early socialization to handling, restraint, and the clinic environment can reduce fear and anxiety during future visits. Ask your veterinarian for tips on making visits less stressful.

Environmental Safety

Keep your puppy away from areas where unvaccinated dogs may have been, such as dog parks, pet stores, and boarding facilities, until the vaccination series is complete. Parvovirus can survive in the environment for months and is resistant to many disinfectants. Your veterinarian can advise you on safe socialization activities.

Limitations of the Preventive Care Schedule

While the schedule outlined in this article is based on standard veterinary guidelines, it has limitations that you should understand.

Individual Variation

Every puppy is different. Breed, size, health status, and maternal antibody levels can affect vaccine response and timing. Some puppies may require additional doses or different intervals. Your veterinarian will tailor the schedule to your puppy's specific needs.

Regional Differences

Disease prevalence varies by geographic location. For example, leptospirosis is more common in certain regions, and heartworm risk is higher in areas with warm, humid climates. Your veterinarian will recommend vaccines and preventives based on local disease patterns.

Product Differences

Different vaccines and deworming products have different labeling and dosing requirements. Some products are approved for use at different ages or intervals. Always follow the product label and your veterinarian's instructions.

Legal Requirements

Rabies vaccination laws vary by state, county, and municipality. Some areas require annual rabies vaccination, while others allow three-year vaccines. Check with your local animal control or health department for specific requirements.

Owner Compliance

The effectiveness of any preventive care schedule depends on owner compliance. Missing doses, delaying visits, or stopping prevention early can leave your puppy unprotected. Set reminders and prioritize your puppy's health.

Professional Escalation Criteria

Knowing when to seek veterinary care beyond routine wellness exams is critical for your puppy's health. The following situations warrant immediate veterinary attention.

Emergency Signs

Seek emergency veterinary care if your puppy shows any of the following signs:

• Difficulty breathing or choking
• Unconsciousness or collapse
• Seizures or tremors
• Severe bleeding that does not stop
• Suspected poisoning or ingestion of a foreign object
• Trauma such as being hit by a car or falling from a height
• Inability to urinate or defecate
• Severe vomiting or diarrhea, especially with blood
• Signs of bloat (distended abdomen, unproductive retching, restlessness)

Urgent but Non-Emergency Signs

Contact your veterinarian within 24 hours if your puppy shows any of the following signs:

• Lethargy or decreased appetite for more than 24 hours
• Mild vomiting or diarrhea lasting more than 24 hours
• Coughing, sneezing, or nasal discharge
• Limping or favoring a limb
• Red, swollen, or discharging eyes or ears
• Skin rashes, lumps, or hair loss
• Excessive scratching or licking
• Changes in urination or defecation habits
• Weight loss or poor growth

Vaccine Reaction Signs

Vaccine reactions are rare but can occur. Mild reactions include lethargy, mild fever, and soreness at the injection site. These usually resolve within 24 to 48 hours. Severe reactions include facial swelling, hives, difficulty breathing, vomiting, or collapse. Seek immediate veterinary care if you observe any severe reaction.

When to Call Your Veterinarian

If you are unsure whether your puppy's symptoms require veterinary attention, call your veterinarian for advice. Describe the symptoms, when they started, and any relevant history. Your veterinarian can help you decide whether to schedule an appointment or seek emergency care.

Practical Decision Framework for Puppy Preventive Care: Risk Assessment and Schedule Customization

Every puppy presents a unique combination of risk factors that influence the timing and selection of preventive care interventions. A standardized schedule provides a useful starting point, but effective preventive care requires a systematic decision framework that accounts for individual variation. This section provides a practical method for assessing your puppy's specific risk profile, customizing the preventive care schedule accordingly, and documenting the rationale for each decision.

Risk Factor Assessment Matrix

The first step in customizing your puppy's preventive care schedule is to evaluate the following risk factors. Each factor influences one or more components of the preventive care plan.

Maternal Antibody Interference Risk

Maternal antibodies passed through colostrum provide passive immunity during the first weeks of life. These antibodies also interfere with vaccine response. The duration of maternal antibody persistence varies among puppies. According to a review published in Veterinary Microbiology, maternal antibodies can persist for up to 16 weeks in some puppies, which is why a series of vaccine doses is necessary to ensure protection after antibodies wane. Puppies from well-vaccinated mothers or those that nursed adequately may have higher maternal antibody levels that persist longer. Puppies from unknown backgrounds, orphaned puppies, or those with poor colostrum intake may have lower maternal antibodies and may respond to vaccination earlier.

To assess this risk, ask your breeder or shelter about the mother's vaccination history and the puppy's nursing history. If this information is unavailable, assume higher maternal antibody interference and follow the standard three-dose series with a possible fourth dose at 16 to 20 weeks.

Environmental Exposure Risk

The puppy's living environment and planned activities determine exposure risk to infectious diseases. High-risk environments include areas with high dog density, known parvovirus outbreaks, boarding facilities, dog parks, training classes, and homes with unvaccinated dogs. Low-risk environments include homes with no other dogs, limited outdoor access, and no contact with unfamiliar dogs.

For high-risk environments, your veterinarian may recommend starting the DHPP series at 6 weeks, using a four-dose protocol (6, 10, 14, and 16 to 20 weeks), and administering the rabies vaccine at the earliest legal age. For low-risk environments, the standard three-dose protocol may be sufficient.

Geographic Disease Prevalence

Disease prevalence varies significantly by region. Your veterinarian has access to local disease surveillance data. Key regional considerations include:

• Leptospirosis: More common in areas with standing water, rodent populations, and warm climates. Consider vaccination if your puppy will have access to ponds, streams, or areas with wildlife.
• Lyme disease: Endemic in the northeastern, mid-Atlantic, and upper midwestern United States. Consider vaccination if you live in or travel to these areas.
• Heartworm: Risk is highest in warm, humid climates with mosquito populations. Year-round prevention is recommended everywhere, but the specific product and timing may vary.
• Parvovirus: Outbreaks occur in all regions but are more common in areas with high dog populations and inadequate vaccination coverage.

Breed and Size Considerations

Breed and size influence vaccine dosing, deworming protocols, and wellness exam frequency. Large and giant breed puppies have different growth rates and may be at higher risk for orthopedic problems. Some breeds are more sensitive to vaccine reactions. Brachycephalic breeds (flat-faced dogs) may have higher anesthetic risks if sedation is needed for procedures.

Your veterinarian may adjust the timing of spay or neuter based on breed and size. For large and giant breeds, delaying spay or neuter until after growth plate closure (12 to 18 months) may reduce the risk of orthopedic disease. Discuss this with your veterinarian during the 14 to 16 week wellness exam.

Lifestyle and Travel Plans

If you plan to travel with your puppy, board them, attend dog shows or training classes, or visit areas with different disease prevalence, additional vaccinations may be needed. Kennel cough (Bordetella) and canine influenza vaccines are often required by boarding facilities. Lyme disease vaccination may be needed if traveling to endemic areas.

Decision Points for Schedule Customization

Using the risk factor assessment, you and your veterinarian can make informed decisions at each preventive care milestone. The following decision points occur at each wellness exam.

6 to 8 Week Visit Decision Points

• Determine if the first DHPP dose should be given at 6 weeks or 8 weeks based on maternal antibody risk and environmental exposure.
• Select the deworming product based on fecal test results. If no fecal test is performed, use a broad-spectrum product that covers roundworms and hookworms.
• Decide whether to start heartworm prevention at 6 weeks or wait until 8 weeks based on product labeling and mosquito season.
• Assess the need for non-core vaccines based on geographic risk. Leptospirosis vaccination may be started at 8 weeks if indicated.
• Schedule the next visit and confirm the interval (typically 3 to 4 weeks).

10 to 12 Week Visit Decision Points

• Administer the second DHPP dose. If the first dose was given at 6 weeks, the second dose should be at 10 weeks. If the first dose was at 8 weeks, the second dose is at 12 weeks.
• Review fecal test results and adjust deworming if specific parasites are identified. Some parasites, such as Giardia or coccidia, require different medications.
• Assess the puppy's response to heartworm prevention. If the puppy vomited or had diarrhea after the first dose, discuss alternative products.
• Evaluate growth and body condition. Adjust feeding recommendations if the puppy is underweight or overweight.
• Discuss socialization plans and safe activities until the vaccination series is complete.

14 to 16 Week Visit Decision Points

• Administer the third DHPP dose. If a fourth dose is indicated (high-risk environment or known maternal antibody interference), schedule it for 16 to 20 weeks.
• Administer the first rabies vaccine if the puppy meets the minimum age requirement (typically 12 to 16 weeks, varies by state law).
• Review the heartworm prevention schedule and confirm compliance. If the puppy missed a dose, discuss how to proceed.
• Discuss spay or neuter timing based on breed, size, and lifestyle.
• Plan for the next wellness exam. If no fourth vaccine dose is needed, schedule the next exam at 6 to 12 months of age.

16 to 20 Week Visit (If Applicable)

• Administer the fourth DHPP dose if indicated.
• Perform a heartworm test if the puppy is over 6 months of age.
• Discuss transition to adult preventive care schedule, including annual wellness exams and booster vaccinations.

Record System for Preventive Care Decisions

A structured record system helps you track decisions, document rationale, and identify patterns over time. Use the following template to record information at each visit.

Puppy Preventive Care Decision Record

For each entry, include the following details:

• Vaccine product name and lot number (for traceability in case of adverse events)
• Deworming product name, dose, and route of administration
• Heartworm prevention product name, dose, and date given
• Fecal test results (positive or negative, and which parasites were identified)
• Any adverse reactions observed
• Rationale for any deviations from the standard schedule (e.g., "Delayed rabies vaccine due to state law requiring 16 weeks minimum age")

Store this record in a secure location, such as a dedicated notebook or a digital file. Bring a copy to each veterinary visit. If you switch veterinary clinics, provide the complete record to the new veterinarian.

Troubleshooting Common Decision Challenges

Even with a systematic framework, challenges arise. The following troubleshooting guide addresses common situations.

Challenge: Puppy Missed a Vaccine Dose by More Than 2 Weeks

If a vaccine dose is delayed by more than 2 weeks, the puppy may not be fully protected. Contact your veterinarian immediately. In most cases, the veterinarian will recommend giving the missed dose as soon as possible and then continuing the series at the standard interval. If the delay is significant (more than 4 weeks), the series may need to be restarted. Do not assume that a single dose provides adequate protection. The Merck Veterinary Manual states that the vaccine series must be completed according to the labeled interval to ensure immunity.

Challenge: Puppy Had a Vaccine Reaction

Mild vaccine reactions (lethargy, mild fever, soreness at injection site) are common and usually resolve within 24 to 48 hours. Monitor your puppy closely. If the reaction is severe (facial swelling, hives, difficulty breathing, vomiting, collapse), seek emergency veterinary care immediately. For future vaccinations, your veterinarian may pre-medicate with an antihistamine or use a different vaccine product. Document the reaction in your record system and discuss it at the next visit.

Challenge: Fecal Test Shows Parasites Not Covered by Current Deworming

If the fecal test identifies parasites such as Giardia, coccidia, or tapeworms, the standard deworming product may not be effective. Your veterinarian will prescribe a specific medication for the identified parasite. Complete the full course of treatment and repeat the fecal test as recommended to confirm the infection is cleared. Update your record system with the new medication and follow-up test results.

Challenge: Puppy Missed a Heartworm Prevention Dose

If you miss a heartworm prevention dose by less than 2 weeks, give the missed dose immediately and continue the monthly schedule. If the dose is missed by more than 2 weeks, contact your veterinarian. The puppy may need to be tested for heartworm infection before resuming prevention. Do not give a double dose to catch up. Set reminders on your phone or calendar to prevent future missed doses.

Challenge: Puppy Has a Health Condition That Affects Vaccine Timing

If your puppy has a health condition such as a fever, infection, or chronic illness, your veterinarian may delay vaccination until the puppy is healthy. Discuss the specific condition with your veterinarian and follow their recommendations. Document the reason for the delay in your record system. Once the puppy recovers, resume the vaccine series as directed.

Challenge: Moving to a Different Geographic Region

If you move to a different region with different disease prevalence, your puppy may need additional vaccinations or preventives. For example, moving from a low-risk area for Lyme disease to a high-risk area may require Lyme vaccination. Moving from a low-heartworm area to a high-heartworm area may require a different prevention product. Schedule a wellness exam with a new veterinarian within 2 weeks of moving to update the preventive care plan.

Comparison of Vaccine Protocols: Three-Dose vs. Four-Dose DHPP Series

The standard DHPP vaccine series consists of three doses given at 3 to 4 week intervals. Some veterinarians recommend a four-dose series for puppies in high-risk environments. The following comparison helps you understand the rationale for each approach.

Three-Dose Protocol

• Doses given at 6 to 8 weeks, 10 to 12 weeks, and 14 to 16 weeks
• Suitable for puppies in low-risk environments with known maternal antibody status
• Provides adequate protection for most puppies
• Fewer veterinary visits and lower cost
• May not provide adequate protection if maternal antibodies persist beyond 14 weeks

Four-Dose Protocol

• Doses given at 6 weeks, 10 weeks, 14 weeks, and 16 to 20 weeks
• Suitable for puppies in high-risk environments, those with unknown maternal antibody status, or those from high-risk breeds (e.g., Rottweilers, Doberman Pinschers, which may have higher maternal antibody persistence)
• Provides additional protection against parvovirus, which is highly contagious and can survive in the environment for months
• More veterinary visits and higher cost
• Recommended by some veterinary specialists for maximum protection

Discuss with your veterinarian which protocol is appropriate for your puppy based on the risk factor assessment.

Professional Escalation Criteria for Decision Framework

If you encounter any of the following situations, escalate to your veterinarian for guidance:

• Uncertainty about maternal antibody status or vaccination history
• Puppy has a known health condition that may affect vaccine response
• Puppy has a history of vaccine reactions
• You are unable to complete the vaccine series within the recommended interval
• Fecal test results show parasites that require specialized treatment
• You are moving to a different geographic region with different disease prevalence
• Puppy has a breed or size that may require adjusted protocols
• You have questions about spay or neuter timing

Your veterinarian has access to the most current evidence and can provide personalized recommendations based on your puppy's specific needs. The AVMA provides resources for pet owners on vaccine recommendations, and the Merck Veterinary Manual offers detailed information on vaccine protocols and disease prevention. Use these resources to inform your discussions with your veterinarian.

Frequently Asked Questions

At what age should my puppy get its first vaccination?

The first core vaccination (DHPP) is typically given at 6 to 8 weeks of age. This timing allows the puppy to receive protection as maternal antibodies begin to wane. Some breeders or shelters may administer the first vaccine earlier, but the standard protocol starts at 6 weeks. Your veterinarian will confirm the appropriate starting age based on your puppy's history and local disease risk.

How many deworming treatments does a puppy need?

Puppies typically need three to four deworming treatments during their first 12 weeks of life. The first treatment is given at 2 to 3 weeks of age, followed by treatments at 5 to 6 weeks, 8 to 9 weeks, and sometimes at 12 weeks. After the initial series, monthly heartworm prevention that includes intestinal parasite control is recommended. Your veterinarian will determine the exact number of treatments based on fecal test results and local parasite prevalence.

Can I take my puppy outside before vaccinations are complete?

You can take your puppy into your own yard if it is safe and free from unvaccinated dogs. However, avoid public areas such as dog parks, pet stores, and sidewalks where unvaccinated dogs may have been. Parvovirus can survive in the environment for months. Your veterinarian can advise you on safe socialization activities, such as puppy classes that require proof of vaccination.

What is the difference between core and non-core vaccines?

Core vaccines are recommended for all puppies regardless of lifestyle or location. They protect against diseases that are widespread, severe, or zoonotic. Core vaccines for dogs include DHPP (distemper, hepatitis, parainfluenza, parvovirus) and rabies. Non-core vaccines are recommended based on geographic location, lifestyle, and exposure risk. Examples include leptospirosis, Bordetella, canine influenza, and Lyme disease. Your veterinarian will assess your puppy's risk factors and recommend appropriate non-core vaccines.

How often should my puppy have a wellness exam?

Puppies require frequent wellness exams during their first few months of life. The typical schedule includes exams at 6 to 8 weeks, 10 to 12 weeks, 14 to 16 weeks, and 16 to 20 weeks. After the initial series, annual wellness exams are recommended for adult dogs. Senior dogs may benefit from exams every six months. Regular exams allow your veterinarian to monitor growth, detect early signs of disease, and adjust the preventive care plan as needed.

When should I start heartworm prevention for my puppy?

Heartworm prevention should begin as early as 6 to 8 weeks of age, depending on the product. Some products are labeled for use from 6 weeks, while others require the puppy to be 8 weeks or older. Your veterinarian will select an appropriate product and provide the first dose during the initial wellness visit. Year-round prevention is recommended by the AVMA, even in colder climates.

What should I do if I miss a vaccination dose?

If you miss a scheduled vaccination dose, contact your veterinarian as soon as possible. Depending on how much time has passed, your veterinarian may recommend giving the missed dose immediately or restarting the series. Delaying a dose can leave your puppy unprotected. Do not attempt to catch up on your own without veterinary guidance.

How can I make veterinary visits less stressful for my puppy?

You can reduce stress by bringing treats and a favorite toy to the visit. Handle your puppy gently and speak in a calm voice. Allow your puppy to explore the exam room before the veterinarian enters. Ask your veterinarian to use gentle handling techniques and to give breaks if needed. Early positive experiences can help your puppy develop a lifelong comfort with veterinary visits.
