Why Do Dogs Eat Their Puppies? The Real Truth


Are you wondering why dogs eat their puppies?

It’s not something extremely common, but it happens.

Having a newly-born litter of puppies around you can be an exciting event. These little fur balls are so tiny and adorable! But, sadly not all of them grow into adults.

There are many reasons why new-born puppies die, like respiratory problems, mastitis, circulation problems, infections, etc.

But sometimes, it’s the mother who herself kills her newborn puppies.

Let’s talk about this in more detail.

Doggy Cannibalism!?

Let’s talk about cannibalism for a hot minute, shall we?

Cannibalism is when one animal eats another one that belongs to the same species.

Now, cannibalism is very rare when it comes to dogs. It’s even more uncommon in the litter is that is birthed in a house environment rather than that in a kennel which is loud.

Puppy cannibalism may occur exactly at birth or maybe after a few days or weeks. It’s not specific to any breeds as such, female dogs of any pure or mixed breeds can eat their own puppies.

That being said, it may/may not be something that’s inherited. Also, may / may not happen again from one litter to another.

Why Does This Happen!?

Let’s talk in detail about why dogs eat their puppies. It’s a sad thing, but there are quite a few reasons something so tragic happens.

Let’s talk about all the reasons this happens.

1.It’s The Hormones

Sometimes dogs, too need to have C-sections to have puppies. And some dogs who give birth this way are less likely to recognize their little fur balls since the mother’s body doesn’t really release the hormones she should have while giving birth naturally.

So, what does it mean?

Well, since she doesn’t recognize the puppies to be her own, their high-pitched noises and erratic movements can annoy her. She may not let them feed at all.

But, the worst part of all…

The erratic movements can activate her predator instinct, and she ends up killing (and eating) these tiny, helpless babies.

But, there’s another side to this cannibalistic story.

Sometimes, even after natural birth, the hormones kick in after a lag. And before they kick in, the mother can actually just kill off her entire litter. This is especially true for inexperienced mothers.

2. Stressed Out

The mother can end up killing her litter if she’s really stressed.

Yes, you read that right.

Some dogs do the unthinkable to their own puppies if they feel that they don’t have a quiet, secluded place for their litter to live or if they feel that their litter is too big for them to take care of.

And this stress can cause the deaths of the innocent pups.

3. Putting Them Out Of Their Misery

Sometimes you may scream murder without knowing the whole story.

Dogs sometimes kill the sick pups that have something wrong with them (which you might not be able to tell!) so they can focus all their energy on to their healthy offspring.

You must be thinking this is cruel. But it’s not.

I’ll tell you why…

This is simply a part of the dog’s natural selection, which is a part of the dog’s process of natural selection. The sick puppy may attract predators and cost the mother the entire litter.

4. A New Mom

Another problem could be that the female dog was bred too young. That’s exactly why no breeding should happen during the mother’s first heat. Or else, she may not be a stable mom after all.

In cases like this, the mother must be immediately spayed so that she isn’t allowed to have more puppies again.

It is natural for the mother to growl or snap at her puppies ( the notorious ones that need some discipline!), but it shouldn’t happen in week 1 when the puppies are totally defenceless and depend on their mom for everything.

5. Mastitis: Painful Nursing

A pup’s main source of nutrition is it’s mother’s milk.

Mastitis is an infection that makes nursing for the new mother very painful. In fact, the pain is so bad that the dog can actually reject her entire litter.

The Normal Behaviour

First off, you shouldn’t be really accusing if you haven’t seen it happen with your own two eyes. There are many other factors that could have lead to the death of the pups.

Normal Mother-Puppy Interaction

Puppies spend a great amount of time sleeping during week 1 as they cuddle around with their mother. During this week, the mom should be lively interested in her fur balls.

She normally stimulates the little ones to, um, eliminate by licking on their tiny bottoms. And it’s perfectly normal for her to ingest their waste.

No cannibalism happening here, folks!

The Red Flags

● The ideal temperature must be about 85°F degrees during their first days. It should never be less than about 70°F.
Use a heat lamp or heating pad if it’s not around 85°F.
● Some puppies don’t nurse. You need to make sure that all of them must be fed.
● Newborns must sleep close to each other.
● If there’s a puppy that’s acting odd, like, staying away or isolated from others, crying etc. This is a warning sign of something wrong.

Natural Causes of Death

There are several natural as well as medical issues that may have a hand in the pup’s demise.

There’s a thing called Puppy Fading Syndrome which can cause pups to pass away.

This can kill them up to the age of 9 weeks old.

You should keep an eye on the following:

● Pups being either too hot or too cold
● Mom neglecting the pups by refusing to lay next or nurse them
● Physical defects in the pup
● Any Infections

When you notice anything that raises a red flag, you must take your dog and the pups to the veterinarian immediately!

What Can You Do To Prevent The Deaths?

Newborn pups are really vulnerable. In order to keep these furballs healthy and safe, you should watch the babies very closely during the critical period, ie, their first few weeks of life and make sure that the pups are acting and nursing normally.

Talking about observations…

You should also observe the mum’s interactions with her litter and look for any abnormal behaviors. Another thing that’ll help would be you sleeping near the litter for a few days so that if you get to hear muffled cries, you’re there to rescue the baby.

Also, you should take the mum and the pups to go see a veterinary doctor about 24 hours after the birth so as to make sure that there aren’t any retained placentas. Also, to ensure that the puppies are in good health.

Final Thoughts

Cannibalism in dogs in uncommon, but it doesn’t mean that it won’t happen. The new mother usually eats her own puppy if she doesn’t recognize it as her own as a prediction instinct.

Don’t accuse the mom of killing her babies until you’re sure! There are many other natural reasons why the pups die a few weeks after their birth…

Here are a few reasons why it happens:

● An inexperienced mom may kill off her litter as she’s unstable
● The mother may not recognize the pups as her own
● Mothers also tend to kill the pups that are sick or have something ’off’ about them
● Stress could be another factor that could lead to this murder

    My maltipoo just had a single puppy. This isn’t her first litter, more like her 4th. I heard it cry and I checked on her and thought she was cleaning it..until I seen she had punctured its’ neck and heard her crunching Its’ tiny leg. I was mortified and upset. I don’t know exactly how to feel about this or what to do, if anything. Any advice?

  2. Dave Martin says

    I’ve experienced mom eating pups on 2 occasions. My conclusion was that moms mineral levels had been depleted during the whelping process and she simply sacrificed a pup, possibly a sick one, to save her self and the littler. The second time I attributed it to her being overjealous with the umbilical cord remenant and chewing off a back leg. She was an excellent mom otherwise. Your thoughts on this. TIA

  6. Ezrah Moncada says

    Well, Grace I think you should… like, maybe take all pups [or only one] to the vet. He/she will make sure that the baby[s] are healthy. After the vet, if you see the mother trying to eat one or all of the babies, discipline her.
