In this guide, we will discuss why do dogs eat their puppies in detail and how to prevent this habit among mother dogs. 

Quick Summary

The main reasons why dogs may eat their puppies: accidental ingestion, hunger or malnutrition, inability to identify or recognize their puppies, suffering from mastitis, stress, inexperienced motherhood, or mercy killing.

It is not a common or normal behavior for dogs to eat their puppies, and it is important for pet owners to take care of their pregnant dogs to prevent this from happening.

It is not an inherited trait for female dogs to eat their puppies, but certain breeds, such as Staffordshire Bull Terriers, may have a higher likelihood of exhibiting this behavior. It is important to create a stress-free and clean nursing environment for the mother dog and to observe her behavior closely after giving birth.

Here are some of the most common and saddest reasons why dogs choose to eat their puppies

Accidentally Eating the Puppy

A mother dog may accidentally eat her puppy. 

However, how does that even happen? After giving birth, it cleans the pups and removes the birthing sac. During this process, it bites and eats the umbilical cord and the placenta and she may accidentally kill the puppies.

If there are stillborn pups (born dead), it may eat them too. The dog has natural instincts to identify stillborn pups. Accordingly, she either buries the stillborn puppies or eats them during the clean-up after the birthing process. 

It happens accidentally when the mother cannot feel the heartbeat of the newborn. 

Hunger or Malnutrition

Hunger and malnutrition can cause dogs to eat the puppies but it is a rare behavior. 

The mother is more hungry than usual because it lactates milk to feed her puppies. Therefore, it needs more calorie intake than usual.

Technically, a mother dog needs a 25% increase in its diet per puppy.

For example, if there are seven puppies, the mother dog needs a 175% increase in its diet. 

Initially, when the mother dog feels hungry, it will check for food.

Eventually, if she is unable to find any food, it may result in the dog eating the puppies. This is where its natural wild animal instinctive behavior kicks in if it doesn’t get sufficient nourishment. 

As a pet owner, it is your responsibility to identify how much food and nutrition it needs and make the accommodations. 

Doesn’t Identify the Puppy

Female dogs don’t always recognize their young puppies. 

It happens because she doesn’t give birth naturally, as it happens by Cesarean sections (C-sections). In such instances, the mother does not release the typical motherly hormones, and thus, she will not be able to recognize her puppies. 

Hormones such as Oxytocin are the key for dogs to identify their puppies from their point of view, and their natural predatory instincts kick in.

Suffering From Mastitis

Mastitis is an infection caused in the breast tissue after the birth. As a result, the dog’s teats can turn red and swollen. What happens when your dog suffers from Mastitis? It begins to feel significant pain while nursing puppies. 

How does the dog exhibit behaviors during this stage? It will lash out at the puppies, exhibit aggressive behavior, avoid feeding, reject the puppies. In cases of severe conditions, it could potentially eat her puppies.

It’s a serious issue, but you can consult your vet for solutions. As a short-term solution, as a pet owner, you can feed all the puppies using bottled milk formula. But if the Mother is comfortable with nursing, it is best to let her do it!

Giving birth is a stressful process as not all pregnancies are easygoing, especially for first-time mothers. New mothers are new to the lifecycle. Therefore, it can result in stress issues. 

How does your dog behave during stress? It looks tired and scared. As a result, it begins to bite its puppies, growl, and bark. 

Here are some ways you can help your dog to overcome stress:

  • Supply the dog with its preferred and nutritious food. 
  • Show your love as a pet owner.
  • Show sufficient attention.
  • Ensure to keep the male dog away.
  • Never separate the mother and puppies (It can cause anger and make them aggressive).
  • Provide a calm and peaceful environment for nursing.

Ensure to overcome your mother dog’s stress issues to avoid aggressive behavior which may result in her eating her puppies. 

Inexperienced Motherhood

A common fact is that female dogs shouldn’t get pregnant during the first heat cycle. Because it is too young at this stage giving rise to inexperienced motherhood. 

If dogs get pregnant at a younger age or face motherhood for the first time, new mothers may not know how to deal with the pups.

Also, being a mother at a young age is not healthy for a dog. 

Dogs face inexperienced motherhood in puppy mills, too. The owners are concerned about multiplying the offspring and not concerned about the health of the mother. In that case, the Mother may eat its own offspring. 

All you can do is consult a vet for advice and take care of both the mother and its puppies from leading to extreme cases. If you have dogs that give birth at a very young age, you must ensure it doesn’t eat its young puppies. 

Mercy Killing

What’s mercy killing? It’s when a mother kills a pup if it is deformed, ill or weak. 

Indeed, when the pup is not born strong or healthy, the mother dog may eat that specific pup. What type of diseases can unhealthy puppies have? It may have respiratory problems, health complications, and infections.

How can you identify sick puppies in the litter? The unhealthy puppy will not spend time with other puppies in the group, lacks the strength to eat, and is very inactive.

The Mother senses these issues quickly and quite early on.

Before the disease gets spread to other pups in the litter, the Mother is left with two decisions:

  • Eat the unhealthy puppy.
  • Nurse that specific pup to make it healthy.

Eventually, the dog decides from the above choices. In cases of mercy killing, the main intention of the mothers is to safeguard the remaining puppies and consider the fact that the pup will not be able to look after itself as it grows weak or unhealthy.
