Dog labor stages follow a predictable pattern: a long, quiet first stage lasting 12 to 24 hours, a second stage of visible pushing and puppy delivery, and a third stage where the placenta passes after each puppy [1]. Knowing the expected timeline for each stage helps you tell normal progress from a stall that needs veterinary help.

Quick Answer

Stage one labor lasts 12 to 24 hours and has no visible abdominal pushing, only restlessness, panting, nesting, and a drop in body temperature [1][2].
Stage two begins when you see strong abdominal efforts, and each puppy should arrive within 1 to 2 hours of hard pushing [1].
Puppies are normally born 30 to 60 minutes apart, and the whole delivery is ideally finished in about 7 to 9 hours [1].
Stage three is the passing of a placenta, which can happen right after each puppy or with several puppies delivered back to back [1].
Call your veterinarian if stage one runs past 24 hours, if a puppy is stuck in the canal for more than 15 to 20 minutes of hard straining, or if more than 2 hours pass between puppies with active contractions [1].

What Are the Dog Labor Stages?

Labor in dogs is divided into three stages. Stage one is the preparation phase, when the uterus contracts and the cervix opens but you cannot see pushing [1]. Stage two is active delivery, marked by visible abdominal efforts that push each puppy out [1]. Stage three is the delivery of the placenta, which may follow each puppy or come in a batch after several puppies [1].

These stages overlap. A dog can deliver two puppies, then pass two placentas, then rest before the next puppy. That is normal. What matters is the pattern of progress over time, not a rigid sequence.

Dog Labor Timeline: What to Expect Hour by Hour

The table below shows typical timing for a normal whelping. Individual dogs vary, and first-time mothers often take longer than experienced ones.

Stage	Typical duration	What you will see	What you should do
Stage one	12 to 24 hours [1]	Restlessness, panting, nesting, hiding, refusing food, temperature drop in the last 24 hours [1][2]	Set up the whelping box, keep the room quiet, take the rectal temperature twice daily
Stage two, early	First 1 to 2 hours of pushing [1]	Strong abdominal contractions, clear or blood-tinged discharge, water breaking	Watch closely, stay calm, do not interrupt unless she strains hard with no puppy
Stage two, active	Puppies every 30 to 60 minutes [1]	Each puppy delivered with several hard pushes, mother licking and cleaning	Dry the puppy if the mother does not, keep the box warm
Stage two, total	Ideally about 7 to 9 hours, can run 1 to more than 24 hours [1]	Pauses between puppies, sometimes 30 to 60 minutes of rest	Offer water, let her rest, note the time of each birth
Stage three	Minutes after each puppy [1]	Placenta passed, mother may eat it	Count placentas, save any that do not pass for the vet

A normal stage two has shorter intervals between puppies, usually 30 to 60 minutes, and shorter total delivery times [1]. Long gaps with no contractions are more concerning than long gaps with visible effort.

Signs of Dog in Labor Stage One

Stage one is the hardest stage to recognize because there is no pushing. The uterus is contracting and the cervix is dilating, but the effort is internal [1]. Owners often describe their dog as "not herself" for most of a day.

Watch for these signs:

Restlessness and pacing that does not settle
Panting, shivering, or seeking out dark, quiet places
Nesting behavior, scratching at bedding or digging in corners
Refusing food in the last day before labor
A drop in rectal temperature during the final 24 hours [2]
Clear, serous, or slightly bloody vaginal discharge [1]

A body temperature below a set threshold can predict that parturition is within 24 hours, with moderate sensitivity and specificity [2]. Your veterinarian can explain how to track this at home and what value matters for your dog.

If your dog has a history of artificial insemination or timed breeding, you may already have a due date. See Canine Artificial Insemination: Techniques and Timing for how breeding timing affects the expected whelping window.

Stage 2 Dog Labor: Pushing and Delivery

Stage two starts the moment you see real abdominal effort. The dog will lie down, often on her side, and contract her belly muscles in a visible wave. Each puppy is delivered by a combination of uterine contractions and these abdominal pushes [1].

Here is what to do during stage two:

Stay quiet and let her work. Most dogs deliver without help.
Time each puppy. Note the clock when hard pushing starts and when the puppy arrives.
Break the sac if it is still covering the puppy's face and the mother has not done it within a few seconds.
Clear the airway by wiping the nose and mouth with a clean towel.
Rub the puppy briskly with a towel if the mother is not licking it.
Place the puppy at a teat once the mother is settled, or keep it warm in a separate box if she is still delivering.
Log the time, sex, and any notes about the birth.

Most puppies are born head first, but breech (tail first) deliveries are also normal. A puppy that appears in the canal and then disappears back inside between contractions is not necessarily stuck. Give her time to push again.

The entire delivery can take 1 to more than 24 hours, but normal labor is associated with shorter total delivery time and shorter intervals between neonates [1]. If your dog is pushing hard for more than 1 to 2 hours with no puppy, that is a stall [1].

Stage 3 Dog Labor: Placentas and Afterbirth

Stage three is the delivery of the placenta. It usually follows each puppy within a few minutes, but it can also come after two or three puppies in a row [1]. The placenta looks like a dark red, liver-like mass attached to the umbilical cord.

Count every placenta. The number of placentas should match the number of puppies. A retained placenta can cause infection or metritis, so tell your veterinarian if you are unsure whether all have passed.

Some mothers eat the placenta. This is normal behavior and generally not harmful, though it can cause a bout of diarrhea. If you prefer, remove it quickly and dispose of it.

After the last puppy, the mother should settle, nurse, and rest. Her discharge may be clear, serous, bloody, or green (uteroverdin) [1]. Green discharge is normal during delivery but should not continue for days afterward.

When Labor Stalls: Signs Something Is Wrong

Dystocia means difficult or prolonged labor. The longer it lasts, the more risk to the puppies and the mother. One study of placentas from emergency cesarean sections found that each additional hour of dystocia was associated with increased severity of placental congestion, and there were trends toward more necrosis and mineralization [3]. In plain terms, time matters.

Call your veterinarian immediately if you see any of these:

Stage one lasting more than 24 hours with no puppy [1]
Hard straining for more than 1 to 2 hours with no puppy delivered [1]
More than 2 hours between puppies with strong contractions [1]
A puppy visible in the vulva for more than 15 to 20 minutes without progress
Green discharge before the first puppy is born
Bright red bleeding that soaks bedding
A puppy stuck halfway out
The mother becomes weak, collapses, or has a seizure
Temperature above 103°F or below 99°F
No puppy after 24 hours of stage one signs

If your dog has a history of cesarean section, a very large litter, or a single large puppy, your veterinarian may recommend a scheduled surgery instead of waiting for natural labor. Discuss this before the due date.

Common Mistakes Owners Make During Whelping

Even experienced breeders make these errors. Avoid them if you can.

Interrupting too soon. A dog that rests for 30 minutes between puppies is not necessarily in trouble. Give her space.
Missing the temperature drop. Checking rectal temperature twice daily in the last week gives you a real signal that labor is close [2].
Not counting placentas. A retained placenta is easy to miss and can cause problems days later.
Keeping the room too cold. Newborn puppies cannot regulate their own temperature. Chill is a leading cause of neonatal death.
Handling puppies too much. Let the mother clean and stimulate them when she is able. Step in only when she is busy with the next puppy.
Waiting too long to call. A stalled labor is an emergency. It is better to call and be told to wait than to wait and lose puppies.
Forgetting the mother's needs. Offer water and a light meal between puppies. She is working hard.

Supplies and Setup That Matter for Health

Set up the whelping area at least a week before the due date. A quiet, warm, draft-free room works best.

Your supply list:

Whelping box with low sides and clean bedding
Digital rectal thermometer and water-based lubricant
Clean towels, plenty of them
Bulb syringe or aspirator for clearing airways
Dental floss or sterile clamps for umbilical cords
Iodine for dipping cords
Heating pad or heat lamp with a safe, covered setup
Kitchen scale that measures in grams
Notebook or phone app for logging times and weights
Trash bag for soiled bedding and placentas
Phone number for your veterinarian and the nearest emergency clinic

Weigh each puppy at birth and again at 24 hours. Birth weight and early weight changes are important prognostic factors in dog neonatology, and they are influenced by breed, sex, and maternal factors [4]. A puppy that loses more than a small amount of weight in the first day needs veterinary attention.

Limitations and When to Contact a Veterinarian

Every whelping is different. The timelines here describe typical patterns, but your dog's individual case needs a veterinarian's assessment. No article can replace an exam.

Call now (emergency):

Hard straining for more than 1 to 2 hours with no puppy [1]
More than 2 hours between puppies with active contractions [1]
Green discharge before the first puppy
Heavy bleeding, collapse, seizure, or unresponsiveness
A puppy stuck in the birth canal
Stage one lasting more than 24 hours [1]

Call the same day:

You are unsure whether all placentas passed
The mother has a fever, foul-smelling discharge, or seems painful
A puppy is not nursing, is cold, or is crying constantly
A puppy has lost weight since birth [4]
The mother is not producing milk or is ignoring the puppies

Routine visit:

A postpartum checkup for the mother within 24 to 48 hours
Puppy wellness exams in the first week
Any questions about breeding timing or future litters

Frequently Asked Questions

How long does dog labor last from the first contraction?

Stage one alone lasts 12 to 24 hours, and the full delivery can run from 1 to more than 24 hours [1]. Most normal deliveries finish in about 7 to 9 hours, with puppies arriving every 30 to 60 minutes [1]. If your dog has been in stage one for more than a day with no puppy, call your veterinarian.

How do I know my dog is in stage one labor?

Stage one looks like restlessness, panting, nesting, and hiding, with no visible pushing [1]. A drop in rectal temperature during the last day is a useful signal that labor is close [2]. If you are unsure, your veterinarian can examine her and confirm whether the cervix is dilating.

Can a dog rest between puppies without something being wrong?

Yes. Pauses between puppies are normal, and some mothers rest for a while before the next delivery [1]. What matters is whether she is having strong contractions during the pause. If she is pushing hard with no puppy for more than 1 to 2 hours, that is not a normal rest [1].

What does green discharge during labor mean?

Green discharge comes from uteroverdin, a pigment released by the placenta, and it is normal during delivery [1]. Green discharge before the first puppy is born is a warning sign and needs a call to your veterinarian. Green discharge that continues for days after whelping also needs attention.

Should I let my dog eat the placenta?

Many dogs eat the placenta, and it is generally not harmful. The bigger concern is counting them, because a retained placenta can cause infection. If you are not sure how many passed, tell your veterinarian so they can check.
