It is a pet owner’s and a dog breeder’s worst nightmare: a mother killing her puppies. Whether the killing is purposeful or accidental, the sight of the dead puppy is enough to cause shock and disbelief.

This behavior is, unfortunately, not uncommon in the canine world. It actually has a name: *’’infanticide”* But why would a mother dog kill a puppy? There are many reasons, and not all of them are to be condemned.

Is She Actually Killing Them?

First of all, it is important to recognize that the mother dog may not necessarily be killing the puppies. Unless you actually see her killing them or acting in an abnormal way, it would be unjust to assume she is doing it. If you find a puppy dead in the morning, many things could have gone wrong.

Normal Puppy and Mother Interaction

Puppies normally nurse and spend 90% of their time sleeping during their first week. During the first week, the mother should exhibit a lively interest in her puppies. She will stimulate them to eliminate by licking their bottoms and ingesting their waste.

One Way to Help

If the dog had a large litter, you can help by getting a cotton ball, wetting it with warm water, and gently passing it on the pup’s bottom after they nurse, mimicking a mother’s tongue.

Do not use anything other than a cotton ball and be very gentle. Never rub.

Questions to Ask

Is the puppy’s room temperature ideal? It should be around 85 degrees for their first days and never less than 70°F. This means you will have to use a heat lamp, and possibly, a heating pad.
Are the puppies actively nursing?
Are they sleeping close to each other?
Is there a puppy staying away from the others and crying more? These may be signs of puppies not thriving as they should.
What Causes Death

There are many medical conditions that can cause puppies to die. Puppy fading syndrome can cause puppies to die from when they are born up until they are 9 weeks old. According to Hilltop Veterinary Hospital, the syndrome might be caused by:

Puppies being too hot or too cold
Mother’s neglect of the puppies by refusing to lie next to them and nurse them
Physical defects of the puppy
Infections
If you notice anything of concern, take your dog and litter to your veterinarian.

Preventing Death

Puppies are very vulnerable as newborns. To keep them safe and healthy, your best bet would be to watch the litter closely for the first few weeks and look for puppies nursing and acting normally.

Also, watch the mother’s interactions and take note if there are any abnormal behaviors. Sleep near the litter for the first few days. This way if you hear any muffled cries, you can go to the rescue.

In general, you should always take the mother, along with her puppies, to see a vet 24 hours after giving birth to ensure there are no retained placentas and that the puppies are in good health.

Why Would She Do It?

When it comes to finding dead puppies, there are some signs of mother intervention that cannot be mistaken. Disappeared or dead puppies with bite marks, missing their head, and with other significant injuries may be safely assumed to have been killed by their mother.

Accidental Killing

Dogs may at times accidentally kill their puppies by crushing them or smothering them. Not all have the instinct to nose the puppies to the center of the whelping box for safety.

Smothering, crushing, and laying down on the puppies can be prevented by installing railings that help prevent the dogs from accidentally lying on a puppy that may have slipped behind her.

Killing Sick Puppies

Other times, when puppies act sickly or when they have something wrong (which we as owners may not be able to tell), mothers may purposely kill them so they can focus on the healthier ones.

It may start with the mother pushing the puppy away from her. At times, the mother may even eat the puppy. This is not cruelty. It is natural selection and part of the dog’s evolutionary process. If one puppy is sick, it may attract unwanted predators.

Inexperienced or Unstable Mothers

The mother dog may have been bred too young — dogs should never be bred on their first heat — or she may simply not be a stable mother.

In these cases, the mother should be spayed and never be allowed to breed again. As the puppies grow, the mother dog may growl and snap at the puppies that require discipline, but in the first week, puppies are defenseless creatures that depend totally on their mom.

Normally, the mother will bond strongly with them during this time thanks to the “bonding hormone,”oxytocin. When that doesn’t happen, trouble arises.

Stress

Some dogs may kill their puppies if they feel stressed from not having a quiet secluded place for the litter to live. There may be too many people coming to see the litter or the litter may be too big for the dog to handle.

The dam’s stress levels may cause her to do the unthinkable. According to Nicholas Dodman in an article for Petplace, a Rottweiler mother killed her pups after being returned to her from a tail docking. She may have assumed the puppies had been damaged or contaminated in some way, and therefore, their destruction was a way of putting them ‘’out of their misery.”

Lack of Recognition

Some dogs, especially new mothers, might not recognize their offspring as their own. This is especially true for dogs who had a cesarean section. New puppies sound like some prey animals (e.g. rodents.) Some dogs with a rodent-killing heritage might mistake them for prey and might be compelled to eat them.

Problems With Nursing

There is a condition that makes it very painful for a mother to nurse her young (mastitis) The pain might be enough to for her to reject the litter.

Make sure you do your research before breeding your dog, have the mother and litter seen by the vet in the first 24 hrs, and monitor both the mother and the litter carefully for the first few weeks. This should help prevent problems with infanticide.
