Newborn puppies need three things first: clear breathing, steady warmth, and prompt access to their mother’s colostrum. As each puppy is born, clear membranes from the face, gently clear only visible fluid, dry and stimulate with a warm towel, check breathing and movement, then keep the puppy warm while you examine it and supervise nursing. Contact a veterinarian promptly if a puppy is cold, weak, breathing abnormally, bleeding, unable to nurse, or has an obvious physical abnormality.
The first 24 hours matter because puppies are vulnerable and their ability to absorb protective antibodies from colostrum declines rapidly. This guide explains what to do, what to monitor, and when home care is not enough.

Prepare a clean, dry whelping area where the mother and litter can stay together, plus dry towels, a digital gram scale, a thermometer, and your veterinarian’s contact information. Ask your veterinarian in advance how to reach urgent or after-hours care, and seek guidance on cord care and feeding if you may need to assist.
Use a controlled warm area and dry bedding. Newborn puppies cannot regulate their body temperature effectively, so they need a warm environment; however, there is no single room temperature established here for every litter. Keep any external heat carefully monitored, give puppies a way to move away from direct heat, and watch for signs that they are too hot as well as too cold. A veterinarian can advise on the setup for your room, litter, and circumstances. Merck Veterinary Manual guidance on neonatal care and the AKC’s responsible breeding guide both emphasize warmth and careful attention to newborns.

Have a notebook or phone note ready to record each puppy’s arrival, sex, weight, nursing, vigor, and any concerns. If you are not confident about a step—especially tube feeding, resuscitation, or ligating a cord—ask a veterinary professional to demonstrate it rather than improvising.
What do I do immediately after a puppy is born?
Work through the same short sequence for every puppy: uncover the face, check breathing, dry and stimulate, maintain warmth, then assess and record the puppy once stable. If the mother is still delivering, keep the puppy warm and under supervision while allowing her to continue safely.
- Remove membranes from the face. If the birth sac covers the puppy’s nose or mouth, clear it promptly so the face is uncovered.
- Clear only visible airway fluid, gently. Wipe away fluid you can see around the mouth or nose. Do not swing a puppy to clear fluid: the Merck Veterinary Manual warns that swinging can cause concussion or cerebral hemorrhage.
- Dry and stimulate. Rub the puppy with a warm, dry towel, using gentle, purposeful strokes. This helps dry the puppy and stimulate it.
- Check breathing and vigor. Look for breathing and movement, and note whether the puppy responds and appears able to suckle. If breathing is abnormal or the puppy remains weak or unresponsive, contact a veterinarian urgently.
- Keep the puppy warm. Use dry bedding and carefully monitored warmth while the mother delivers the rest of the litter. Avoid direct, uncontrolled heat that could burn or overheat a puppy.
- Once stable, examine and weigh it. Record the puppy’s sex, weight, and initial vigor, then check its anatomy and reflexes as described below.
- Return a vigorous puppy to the mother and supervise nursing. Make sure each puppy finds a teat and begins nursing promptly.
These steps are immediate stabilization, not a substitute for veterinary resuscitation. Professional newborn resuscitation can involve airway management, oxygen or ventilation when indicated, heart-rate assessment, and temperature control. At home, focus on clearing visible obstruction gently, drying and stimulating, warmth, and urgent veterinary contact; do not improvise drug doses or advanced procedures. See the RECOVER newborn resuscitation guidelines and the veterinary review on neonatal resuscitation.
How do I keep newborn puppies warm without overheating them?
Keep puppies dry in a warm, controlled environment, use external heat cautiously, and monitor the puppies rather than relying on a rigid room-temperature target. Newborns have limited ability to regulate body temperature, but too much or poorly controlled heat can also cause harm.
Use clean, dry bedding and check the puppies frequently. Make sure heat is not applied directly in a way that could burn them, and arrange the area so the litter is not trapped against a heat source. Reassess any puppy that feels cold, is unusually weak, separates from the litter, or does not nurse; a cold or weak newborn needs prompt veterinary advice, not simply more heat and waiting.

Do not assume one temperature suits every whelping area or litter. The evidence here does not establish a universal home-room temperature. Ask your veterinarian for a temperature and heating plan appropriate to your setup, and use a thermometer to monitor the environment as advised. The AKC’s breeder guidance states that a newborn puppy cannot control its body temperature and must be kept warm; Merck’s neonatal care guidance likewise treats temperature management as a core part of care.

Encourage nursing as soon as a puppy is stable and ensure every puppy gets colostrum as early as possible, within the first 24 hours. Colostrum is important because it supplies antibodies that help provide passive immunity, and the window for absorbing them is short.
Supervise each puppy’s first efforts: check that it can find a teat, latch, and nurse. A puppy’s presence beside the mother does not by itself confirm that it has fed. Note which puppies nurse and whether any repeatedly miss out or appear too weak to latch. The UC Davis-authored review says adequate colostrum ingestion must occur promptly—within 24 hours postpartum—for puppies and kittens to acquire passive immunity. Merck reports that intestinal absorption of IgG generally ceases by 24 hours after parturition. Read the review on neonatal resuscitation and early care and Merck’s guidance for newborn puppies and kittens.
If a puppy is not nursing, seek veterinary advice promptly. Do not force-feed or give medication that has not been prescribed. A veterinarian can assess why nursing is failing and advise on a safe feeding plan, including whether supplemental feeding is needed.
How should I examine each puppy during the first day?
Once a puppy is stable and warm, make a brief, gentle check of its mouth, reflexes, body, breathing, and elimination openings, and record its weight and vigor. The purpose is to notice problems early, not to diagnose them at home.

- Mouth: Look for an obvious cleft palate or other visible abnormality.
- Suckle reflex: Note whether the puppy appears able to suckle.
- Limbs and coat: Check for obvious limb abnormalities and assess the coat and overall appearance.
- Breathing and mucous membranes: Observe breathing and the appearance of the visible mucous membranes; abnormal breathing or cyanosis requires urgent veterinary care.
- Abdomen and heart sounds: These are part of a newborn examination. If you are not trained to assess them, have a veterinarian examine the puppy rather than trying to interpret findings yourself.
- Anus and urethra: Confirm that the anus and urethral opening appear patent, or open, and seek veterinary help if anatomy looks abnormal.
- Umbilicus: Check for bleeding, redness, swelling, or discharge.
- Weight and vigor: Weigh the puppy on a gram scale and record the result, along with its activity and nursing behavior.
Arrange veterinary assessment for abnormalities or uncertainty. Merck’s neonatal care guidance recommends examining newborns for issues including cleft palate, patent urethra and anus, reflexes, breathing, heart sounds, abdomen, and umbilicus. A home check helps you notice and report concerns; it does not replace a veterinary examination.
How do I care for the umbilical cord?
Follow veterinary guidance for cord care, including how to ligate, trim, and disinfect the stump. RECOVER recommendations describe ligating and trimming the cord to about 1 cm and disinfecting it with 2% tincture of iodine.
Because a newborn is delicate and cord technique matters, ask your veterinarian to show you what to do if you have not been instructed. Afterward, observe the stump: a normal stump is dry, without surrounding redness. Bleeding, redness, swelling, or discharge should prompt veterinary advice. See the RECOVER newborn resuscitation recommendations and Merck’s newborn care guidance.
What should I monitor throughout the first 24 hours?
Keep a simple record for every puppy, and recheck the litter frequently. Track weight, nursing, warmth, vocalization, activity, and elimination so you can spot a change or identify a puppy that is missing out.
| Record | What to note | Why it matters |
|---|---|---|
| Identity | Sex and a way to distinguish each puppy in your notes | Helps match weights and observations to the correct puppy. |
| Weight | Initial weight and subsequent readings | Provides a concrete way to follow each puppy’s condition; ask your veterinarian how often to weigh and what changes warrant a call. |
| Nursing | Whether the puppy finds a teat and nurses | Helps confirm that each puppy has access to colostrum. |
| Warmth and activity | Whether the puppy is warm, active, and responsive | Coldness, isolation, or persistent weakness can signal trouble. |
| Vocalization and elimination | Notable changes or concerns | Completes the first-day picture to share with your veterinarian. |
| Umbilicus | Dryness, bleeding, redness, swelling, or discharge | Makes it easier to notice a problem at the cord site. |
A puppy that is quiet only while asleep and nurses normally is reassuring. A puppy that is cold, isolated, weak, or not nursing is not simply a puppy to watch and hope will improve; contact a veterinarian promptly. A written log also helps you explain the sequence of events and changes accurately if you call for advice.

What if a newborn puppy will not nurse?
Contact a veterinarian promptly rather than waiting through the first day or forcing a feed. Failure to nurse can put the puppy at risk of missing time-sensitive colostrum, and the reason for the problem needs assessment.
Veterinary guidance supports supplemental milk by bottle or tube when nursing fails, but the method should be chosen with professional advice. Tube feeding carries aspiration risk and should be taught by a veterinary professional; do not attempt it from written instructions alone. Do not force a bottle feed, use unprescribed medication, or assume that a puppy that is too weak to latch can be safely fed without help.
If the mother rejects a puppy or the litter is orphaned, the puppy may need an alternative milk source and a plan for warmth, feeding, and close monitoring. Ask a veterinarian to guide that plan. The Merck Veterinary Manual and AKC breeder guidance discuss supplemental care; this is not a situation for guesswork about feeding technique or quantities.

Call promptly for coldness, persistent weakness, abnormal breathing, cyanosis, bleeding, failure to nurse, or abnormal anatomy. Do not wait for the end of the first 24 hours when a puppy is showing a serious sign.
- Cold or persistently weak: A puppy remains cold, isolated, or weak despite being kept dry and warm.
- Breathing concerns: Breathing is abnormal, or the puppy is not breathing normally after immediate gentle clearing, drying, and stimulation.
- Cyanosis: The puppy’s visible tissues look bluish or otherwise suggest inadequate oxygenation.
- Bleeding or cord concerns: The umbilical stump bleeds, becomes red or swollen, or has discharge.
- Feeding failure: The puppy will not nurse, cannot latch, or is too weak to feed.
- Possible anatomical abnormality: You see a cleft palate, an apparently closed or abnormal anus or urethral opening, or another concerning body or limb abnormality.
Newborns can deteriorate quickly, and a home caregiver cannot provide all parts of professional neonatal resuscitation. Merck reports a neonatal mortality range of 9%–26%, with the highest mortality occurring in the first week. That figure is a reported range, not a prediction for an individual litter; it underscores why close observation and early veterinary involvement matter. See Merck’s neonatal care guidance and the RECOVER guidelines.

What does a practical first-day routine look like?
For each puppy, stabilize first, then examine and document, then supervise feeding and keep monitoring. Repeat the checks frequently throughout the first day rather than treating the birth examination as the final check.
- At birth: Uncover the face, gently clear visible fluid, dry and stimulate, check breathing and movement, and keep the puppy warm.
- When stable: Record sex, weight, and vigor; inspect the mouth, limbs, openings, breathing, and umbilicus; note the suckle reflex.
- Before returning to the litter: Follow veterinary instructions for cord care and check for bleeding or other problems.
- At the mother: Supervise nursing and confirm each puppy can access a teat and feed.
- During the day: Recheck warmth, activity, nursing, vocalization, elimination, weight as advised, and cord appearance. Update the log.
- At any red flag: Call a veterinarian promptly; do not wait for a routine check or attempt advanced resuscitation or tube feeding without training.
The first day is not a reason to separate a stable puppy unnecessarily from its mother. It is a period for repeated, calm observation and quick action when a puppy is not breathing, warming, or feeding normally.
Frequently Asked Questions
How serious is the first week for newborn puppies?
Merck reports neonatal mortality of 9%–26%, with the highest mortality in the first week. That broad reported range does not predict what will happen to a particular litter, but it is one reason close observation and prompt veterinary care matter.
Can a puppy still benefit from colostrum if it nurses after the first day?
A puppy may still nurse, but the opportunity to absorb colostrum antibodies is time-sensitive: Merck says intestinal IgG absorption generally ceases by 24 hours after parturition. Do not delay seeking veterinary advice for a puppy that has not nursed.
Is tube-feeding a newborn puppy something I can learn from a video?
Tube feeding can cause aspiration if performed incorrectly, so a veterinary professional should assess the puppy and teach the technique directly when it is appropriate. Do not attempt it based only on a video or written directions.
Does every newborn puppy need the same room temperature?
The sources cited here do not set one universal home-room temperature for every litter. Ask your veterinarian for a plan for your specific whelping area, and monitor the puppies carefully to avoid both chilling and overheating.
