Do not give your dog the whole can of pumpkin at one time.
Pumpkin is a natural and inexpensive food that can help your dog recover from diarrhea. Canned pumpkin without any additives or spices will firm up your dog's stool.
How to use pumpkin to treat dog diarrhea
Purchase plain canned pumpkin from a grocery store. Do not get pumpkin pie filling or anything with spices.
Serve the canned pumpkin to your dog with meals. Add one tablespoon of canned pumpkin to her regular dog food if she's a fifty pound dog and one teaspoon if she's a small dog, such as a chihuahua.
Plain boiled rice is another option for a dog with an upset digestive tract. You can mix the canned pumpkin in with the rice.
Continue the pumpkin regimen every day until you notice a firmer stool.
Contact your vet if your dog still has digestive problems after a week of eating canned pumpkin.
