Dog Stomach Problems: What to Do When Your Pup Has an Upset Tummy

Dog stomach problems usually show up in the form of vomiting or diarrhea—and let’s be honest, it rarely happens outside where it’s easy to clean up. Nope, it’s usually on the bedroom carpet… or even worse, your bed!

But don’t panic—many tummy troubles are mild and clear up with a bit of rest and TLC. Here’s what you need to know to help your pup feel better fast.

Identifying The Causes

One of the most common reasons for an upset stomach is a classic garbage raid—dogs can’t resist a tempting (but gross) snack.

Other times, it might be thanks to a well-meaning family member who shared some table scraps that didn’t sit well.

Of course, the most concerning cause is when your dog eats something toxic. If that’s even a remote possibility, skip straight to calling your vet.

If the upset is due to garbage or food sensitivity, symptoms usually pass within 24 hours. But if it lasts longer—or your dog has a fever—you should definitely call the vet.

Fasting For Dog Stomach Problems

If vomiting is the main issue, one of the best things you can do is:

Give your dog’s digestive system a break.

That means skipping a meal or two. Don’t worry—this short fast won’t harm your dog. In fact, it often helps calm things down.

Water should still be available, but only in small amounts. Letting your dog gulp water can trigger more vomiting or nausea, so offer just a few sips at a time throughout the day.

Reintroducing Food After A Fast

Once your dog is no longer vomiting and seems more like her usual self, it’s time to offer small amounts of bland food throughout the day.

Start with things like:

Boiled hamburger (drained)
Poached chicken
Cottage cheese
All mixed with a bit of plain rice or cooked potato.

Keep the portions very small at first. If your dog keeps the food down and seems interested in more, you can gradually increase the portion size and frequency.

When the Problem is Diarrhea Instead

If your dog has diarrhea instead of vomiting, you can still do a short fast—but hydration becomes even more important.

If she’s reluctant to drink, spike her water with a little dog-safe broth to encourage her to take in more fluids.

Dehydration is the biggest concern with diarrhea, so keep a close eye on her water intake.
