What Science Is Teaching Us About Puppy Resuscitation

Sometimes responsible breeding means being willing to reconsider what we thought we knew.

Anyone who has spent enough years in a whelping box understands that not every puppy arrives ready to take on the world. Most do, of course, but occasionally a newborn enters the world without the vigorous movement, strong cry, or immediate breathing we hope to see. Those are the moments when preparation, knowledge, and the ability to respond calmly become particularly important.

For generations, breeders have shared techniques for helping struggling newborns. Some were learned from veterinarians, others from mentors, and many were passed along because they appeared to work. As with so much in animal husbandry, experience became our teacher.

But experience, valuable as it is, does not always tell us why something works, whether a different approach might work better, or whether some of our familiar practices carry risks we did not fully understand.

Recently, I have been following the educational work of Dr. Emmanuel Fontaine, DVM, whose articles examine canine reproduction, neonatal care, and the science behind successful breeding. His discussion of the updated neonatal resuscitation guidelines is particularly worthwhile for anyone who breeds dogs.

What caught my attention was not simply the information itself, but the willingness to acknowledge that some longstanding recommendations have changed.

That is something I believe all breeders, regardless of how many years we have been involved, should be willing to consider.

The First Breath Matters

In August 2025, the RECOVER Initiative published evidence- and consensus-based guidelines specifically addressing resuscitation of newborn puppies and kittens.

Unlike adult dogs, newborn puppies are undergoing a remarkable physiological transition. Until birth, oxygen reaches them through the placenta. After delivery, their lungs must expand and assume responsibility for oxygen exchange while their circulation adapts to life outside the uterus.

When that transition does not happen normally, restoring effective breathing becomes the immediate priority.

One important change in current guidance concerns the familiar practice of suctioning every newborn puppy’s mouth and nose.

Many breeders were taught to reach immediately for a bulb syringe, assuming that removing fluid must come before breathing can begin. We now understand that routine suctioning is unnecessary for vigorous newborns and can delay more important interventions.

For a healthy puppy that is moving, breathing, and responding normally, simply drying the puppy and allowing the dam to provide appropriate maternal care may be all that is necessary.

A struggling puppy, however, requires a different response.

Learning to Recognize a Puppy That Needs Help

One of the most useful concepts in Dr. Fontaine’s discussion is the importance of assessing the newborn before deciding what intervention is necessary.

Rather than treating every puppy identically, we should learn to recognize the difference between a vigorous newborn and one whose transition to independent breathing is compromised.

A vigorous puppy generally demonstrates active movement, good muscle tone, regular breathing, and a response to handling or stimulation. A puppy that is limp, gasping, not breathing, or showing poor responsiveness needs immediate attention.

Color can provide additional information, although it should not be considered in isolation. This is particularly worth remembering with Staffords, where pigmentation can make visual assessment more difficult.

Current guidelines also emphasize evaluating heart rate when a newborn is compromised, something that may require equipment and veterinary training.

The important lesson is that resuscitation should be guided by what the puppy is actually doing, rather than simply following a familiar routine with every delivery.

Warmth, Stimulation, and Breathing Support

One of the simplest tools in the whelping room remains one of the most important: a clean, warm towel.

For a newborn requiring assistance, promptly drying and gently but briskly rubbing the body can stimulate breathing while helping prevent heat loss.

Temperature management matters because newborn puppies have very limited ability to regulate their own body temperature. A chilled puppy is already at a physiological disadvantage.

However, stimulation must never become a reason to delay necessary breathing support.

The 2025 RECOVER guidelines recommend beginning assisted positive-pressure ventilation as early as possible for puppies that are gasping or not breathing. When indicated, this should ideally be delivered using a properly fitted neonatal mask and resuscitation bag, with the goal of beginning within the first minute after birth.

This is an important distinction. A puppy that is not breathing effectively needs air reaching its lungs, not prolonged rubbing while we hope for a response.

For breeders, the practical lesson is to establish an emergency plan with their veterinarian before a litter is due, including training in the correct use of neonatal resuscitation equipment.

These are techniques worth learning before they are needed.

Some Familiar Practices Deserve Retirement

Perhaps one of the more significant recommendations concerns the practice of swinging newborn puppies to remove fluid from their airways.

This method has been taught and practiced for years, often with the sincere belief that centrifugal force helps clear fluid from the respiratory tract.

The updated RECOVER guidelines recommend against it.

Swinging a newborn can cause injury, and it is not an appropriate substitute for proper airway assessment and respiratory support.

Likewise, routine deep suctioning is no longer considered appropriate. Gentle suction may still be indicated when a non-vigorous puppy has excessive fluid obstructing the upper airway, but it should be followed promptly by necessary breathing support.

This is where science becomes especially valuable. It allows us to distinguish between something we have always done and something we can demonstrate is beneficial.

The two are not necessarily the same.

Resuscitation Is Not Simply CPR

Another distinction worth understanding is that newborn resuscitation is not identical to cardiopulmonary resuscitation in an adult dog.

In a newborn whose heart is still beating but whose breathing is inadequate, the initial emphasis is on establishing effective ventilation.

Chest compressions are reserved for specific circumstances, including an absent heartbeat or a critically low heart rate that does not improve with appropriate ventilation and oxygen support.

The recommended techniques, timing, and compression-to-ventilation ratios also differ from those used in adult canine CPR.

These are not procedures breeders should improvise from memory or attempt to learn for the first time during an emergency. They deserve proper instruction, suitable equipment, and a veterinary emergency plan.

A written protocol in the whelping room is useful, but it is no substitute for hands-on preparation.

Experience and Education Should Work Together

I have always believed that breeding dogs responsibly involves considerably more than choosing a sire and dam, studying pedigrees, or evaluating the resulting puppies.

It also means accepting responsibility for the lives we bring into the world, including preparing for situations we sincerely hope never occur.

Experienced breeders possess something that cannot be learned entirely from textbooks. Years of observation teach us to recognize subtle changes in behavior, maternal instincts, puppy vigor, and the progression of a normal or difficult delivery.

That experience matters.

But there is a difference between respecting experience and becoming unwilling to question it.

When better evidence becomes available, we should be curious enough to examine it and responsible enough to change our practices when warranted.

Dr. Fontaine’s educational work is a useful reminder that learning does not end when we become experienced. In many ways, experience should make us more interested in understanding the science behind what we observe.

The whelping box has taught many of us remarkable lessons over the years. Veterinary research gives us an opportunity to understand those lessons more completely.

And if updating one familiar practice offers a newborn puppy a better chance of survival, surely that is reason enough to keep learning.
