Think about it: a mother dog in the wild licks her puppies clean. That includes their vomit. It’s a natural way to keep the den scent-free so predators don’t sniff them out. Your domesticated dog still has that ancient instinct—it’s just applying it to your living room carpet.
And here’s the kicker: puppies often eat their own sick because their digestive systems are still learning the ropes. They might be trying to “re-digest” nutrients that got ejected too soon. Weird? Yes. Efficient? Surprisingly, yes.
The “I Ate Something Bad” Safety Net
Dogs have a superpower humans lack: they can taste and smell things we can’t even imagine. That vomit might not just be a mess—it could be a warning signal. If your dog ate something toxic, throwing up is the body’s emergency brake. Eating it again might seem insane, but in the wild, it prevents leaving a poison trail for others.
Imagine you accidentally ate a rotten berry. Your body says, “Nope,” and you barf. A wild dog would then eat that barf to keep the den clean—and to avoid attracting bigger predators. Your sofa is now the den. Gross, but logical.
