It’s one of those things that nobody likes to talk about, but the fact is, mother dogs will occasionally eat their puppies. It’s rare and tragic but unfortunately, it does happen.
There are a few theories as to why this occurs. We’ll explore prominent ones below, as well as discuss strategies for preventing it from happening in the future.
Eating Her Young Doesn’t Make a Dog “Bad”
Before we explore why a dog might eat her young, it’s important to note that animals don’t have the same moral compasses that humans do. They’re just following their instincts, not trying to be monsters.
In some cases, in fact, she might be trying to be a good mom — just in a misguided way.
As a result, you shouldn’t punish a dog that eats her young. By all means, try to stop her from doing it again, but don’t judge her for it. She’s not trying to be evil, and she’s still the same dog you’ve known and loved.
Is It an Inherited Trait?
There doesn’t seem to be any sort of predisposition within certain breeds to eating puppies, with one big exception: Staffordshire Bull Terriers are notorious for killing their puppies. That’s not to say that every Staffordshire Bull Terrier will do it, but you should keep a close eye on yours just in case.
Beyond that, though, there doesn’t seem to be any sort of inherited trait that makes one dog more likely to commit cannibalism than another. Instead, most of the factors seem to be external.
She May Not Recognize Them
Dogs don’t always recognize their puppies as their own. If they don’t realize that the puppies are theirs, then their natural predatory instincts may kick in, with tragic results.
This is especially common in dogs who deliver via Cesarean section. C-sections prevent their bodies from releasing the natural hormones that cause them to recognize their young, and it also prevents them from experiencing the act of birth.
Sometimes, though, the hormones do kick in — there’s just a little bit of a lag. In those cases, preventing the mother from eating the young can make all the difference in the world, as they’ll resume their normal maternal duties as soon as the hormones take effect.
She May Be Inexperienced
Dogs that are bred too young may not know how to deal with puppies. Dogs who are bred during their first heat are especially vulnerable to committing cannibalism.
This is a big problem in puppy mills because the owners care only about maximizing the number of offspring that each female can have. There’s no concern for proper care, and as a result, dogs can be forced into motherhood before they’re ready — and their puppies can pay the price.
Of course, sometimes accidents can happen, even without something as nefarious as a puppy mill involved. If you have a dog that’s giving birth early, you’ll need to be vigilant about stopping her from eating her kids.
It’s just one more reason that spaying and neutering dogs is so important. Doing so can save the lives of countless puppies (in more ways than one).
She May Be Stressed
All animals — including humans — do strange things when they’re under stress. For nursing dogs, this can include killing their puppies.
One of the biggest sources of stress for a new canine mother is a busy birthing area. If there are people constantly coming and going or other animals are harassing her, a mother may flip out and start eating puppies. It’s horribly out of character, but it happens nonetheless.
You should do everything you can to give a new mom a quiet, secluded nursery. Set aside a room of your house or barn, and make it as comfy as possible for her. Be sure to give her plenty of food and water as well, so she doesn’t have to leave her pups to go looking for sustenance.
Of all the reasons that a mom might eat her kids, stress is one of the easiest to avoid — so do your best to avoid it.
She Might Have Made a Mistake
After giving birth, a dog will clean her pups, bite off the umbilical cord, and eat her placenta. Sometimes, she devours more than just the afterbirth, though.
The vast majority of the time, any puppy that gets eaten will have been stillborn.
Most stillborn pups give off certain hormones that alert the mother to that fact, and she’ll usually drag off any puppies that didn’t make it and bury them. If for some reason, she doesn’t recognize those hormones, though, she may eat the body along with the placenta.
The good news is that as long as she only eats the stillborn pups, the mother should still be trustworthy around the rest of her newborns.
She Might Be Committing a Mercy Killing
Not every puppy is born strong with a high chance of survival. Some are weak, scrawny, or otherwise unhealthy.
In the wild, these dogs would have virtually no chance of surviving. As a result, the mother might not want to waste precious resources feeding a dog that won’t make it. Instead of letting the pup wither and die, the mom may just put the runt out of its misery.
This may seem barbaric, but it’s the best way to ensure that the rest of the group survives. It’s a behavior that serves the animals well from a Darwinian perspective.
Of course, advances in veterinary care have made it possible for many of these weak puppies to survive and thrive — but most dogs don’t keep up with advances in veterinary care. It’s up to you, then, to rescue the puppy and try to save them before their mom finishes them off.
Be on the lookout for any pups that aren’t nursing or that have wandered off away from the rest of the litter. Also, if the dog is clearly sick or deformed, the mother may not let it nurse. In these cases, you’ll have to take on the mantle of motherhood yourself.
She May Have Mastitis
Mastitis is a painful infection of the breast tissue that sometimes occurs after birth. The dog’s teats can become red, swollen, and painful to the touch. This makes nursing excruciating.
However, the puppies don’t realize that — all they know is that they’re hungry and the teats are where the milk is. If they’re too eager to latch on, they may hurt their mother, causing her to lash out and potentially kill them.
She may also reject and abandon her puppies. This can be just as fatal as being attacked, and in some cases, the mom will come back to eat the young that didn’t make it.
Fortunately, mastitis is treatable, so as long as you get your dog prompt medical care, it shouldn’t be fatal to the puppies. You may need to bottle feed them until the mom’s ready to take over again, though.
Not All Dogs Make Good Mothers
The simple fact is that not every dog is cut out for motherhood. Some dogs are naturally unstable for one reason or another, and they shouldn’t be allowed to have puppies.
If a dog has already killed or eaten one of her puppies, you should take the rest away from her, as they’re all at risk. Also, that dog should be fixed as soon as possible, as it’s incredibly likely that she’ll repeat her murderous behavior with future litters.
One Big Myth and Other Things to Keep in Mind
One myth about newborn dogs is that the mother will reject her young if the scent of a human gets on them. That’s almost certainly not the case, especially if the mother is accustomed to being around people.
In fact, it may be essential for you to handle the puppies, especially if any are sick, injured, or not feeding. You may need to keep them alive until the mother can resume caring for them again.
However, it’s possible for you to introduce infection into the puppies by handling them, and that may cause the mother to eat them. You may carry diseases like parvo on your clothing or shoes, which can then infect the pups. Wear clean clothes, especially if you’ve interacted with other dogs recently.
Also, you may notice the mother growling or snapping at her puppies. This is perfectly normal, as she’s disciplining them the same way any mother would. This discipline shouldn’t happen within the first week of their lives, though, so you may need to intervene if she’s showing aggression too soon.
One other thing to be aware of is that while most doggie mothers won’t eat their puppies, it doesn’t mean that other dogs won’t. Many dogs will happily eat another pooch’s young, as it gives their own offspring an advantage. That’s why you shouldn’t let any dog other than the mother around the new litter.
Most Dogs Make Excellent Mothers
As long as your dog is mature, healthy, and otherwise well-behaved, you shouldn’t have to worry about her eating her puppies. It’s a rare behavior, and there are usually clear underlying causes behind it.
Canine cannibalism is an unfortunate thing, but it does happen. Fortunately, you’re not likely to experience it, and if you do, there are things you can do to make sure it never happens again.
