How Long Can A Dog Go Without Pooping?

Pooping is as natural for your dog to do as it is for you. It’s the way of our bodies to get rid of everything that it can’t use or get nutritional value from. That’s why we shouldn’t go too much without it. But sometimes our bodies just don’t want to do it, and the same goes for canines. In those moments, a dog owner may wonder: How long can a dog go without pooping? We did some research on it, and here’s what we got.

How long can a dog go without pooping?

Dogs can go for about 48 hours without pooping. However, if your dog didn’t poop for longer than those 48 hours — take him to the vet immediately!

More than 48 hours without pooping could be a sign of different gastrointestinal diseases that your pet may have.

Why is my dog not pooping?

There are different reasons as to why your dog might isn’t pooping. Normal and healthy dogs will poop 1-3 times a day. That mainly depends on the amount of food that your dog consumes and the type of food that he eats.

Other factors will also play a role in how much your dog poops. These include stress, mineral intake, exercise and how much he sleeps.

If your dog doesn’t eat enough, doesn’t get any exercise, and is basically being neglected and living an unhealthy life — it’s pretty clear that his digestive system won’t work properly and that he won’t poop as often as he should.

Another reason why dog don’t poop is constipation. While constipation is pretty rare in dogs, it can still happen.

However, in some cases constipation can also be a sign of an underlying disease or food sensitivity. Like we already stated — if your dog didn’t poop for more than 48 hours, visit a vet immediately.
