Why Do Dogs Eat Their Puppies? (& How to Stop It)


Giving birth to young ones is a wonderful experience for both humans and pets. Dogs will give birth to puppies, and they will show maternal love and behavior. There are certain behaviors that put puppies in danger. Dogs eating puppies is one of the behaviors that they may display. So, Why do dogs eat their puppies? In this article, we explain the reasons that make dogs eat their puppies.

The following are seven reasons that make dogs eat their puppies;

1. Does Not Recognize Their Puppies 

If a mother dog does not recognize her puppies, it may lead her to kill them and eat them. This is more likely to happen if puppies are delivered by caesarean section.

2. Suffering from Mastitis

When a mother dog suffers from mastitis, it makes the teats painful to touch, making nursing very difficult. 

If the puppy attempts to feed, the mother may lash out and injure or kill it, therefore eating it as a result.

3. Hunger and Malnutrition

Eating puppies is a problem when dogs are hungry because they lactate milk, which passes the needed nutrition to their puppies. Therefore, they will require enough food to lactate them and replenish lost energy during birth.

Therefore, if dogs don’t get food nearby, they start to look for food, and their puppies will be the only option. Hunger will eventually kick in their canine instincts, and they may eat their puppies without fail.

4. Stress

The main reason for stress that leads dogs to eat their puppies is busyness and noise around the birthing area. 

If there are people constantly coming and going or other animals harassing her, a mother dog may flip out and start eating puppies out of stress.

5. It Is Mercy Killing 

Another reason dogs eat their puppies is mercy killing. It happens when there is a weak pup that most likely won’t survive in the litter; these could be sick, deformed, injured, or naturally weak. 

The mother dogs may prioritize healthy puppies over wasting resources on weak ones. This may result in mother dogs eating their weak and ill puppies to keep others safe.

6. As Result of Mistake 

Dogs may accidentally kill their puppies, especially if it is their first birth. Dogs will accidentally eat their puppies, thinking that the puppy is stillborn and eating its body. 

Also, they can eat them along with the placenta that contains pups, not knowing they are still inside the placenta.

7. They May Be Inexperienced or Young

Dogs that are bred too young may not know how to deal with puppies. This is because they are still young and not prepared to deal with maternal responsibilities, hence abandoning them and, as a result, eating them.

Note that a mother dog eating her dead puppy is not a common occurrence. Therefore, a dog eats a dead puppy because the puppy may be stillborn, have developed a genetic condition, or the mother dog may have had a miscarriage.

5 Reasons Why a Dog Kills Her Puppies 

In some cases, a dog may exhibit aggression towards her puppies and potentially kill them. This can be a result of the following five reasons;

1. Disease or Illness 

This is the most common reason why dogs kill their puppies. For instance, if a puppy is born with a deformity or disease, the mother dog may kill the weak or sickly one and focus her attention on the healthy ones.

2. Lack of Maternal Instinct

Some dogs may lack maternal instinct and proper care of their puppies due to neglect, lack of socialization, or genetics. 

Therefore, without maternal instinct, a dog may kill her puppies out of negligence or because the dog does not know how to care for them.

Out of fear, a dog may kill her puppies. The mother dog may feel threatened by her children and lash out in hostility. 

In addition, if a dog feels scared or intimidated by her puppies, she may kill them in an attempt to protect herself. 

4. Competition for Resources 

This is another reason that makes a dog kill her puppies. 

This occurs if a mother dog feels she does not have enough food or water to care for her puppies, and she ends up killing them to prevent them from competing with her for limited resources.

5. Stress or Anxiety
