On the opposite end of the spectrum, pumpkin can also help with constipation in dogs. The Merck Veterinary Manual states that adding 1-to-4 tablespoons of pumpkin per meal to the diet of a dog suffering from constipation can help ease mild constipation. It is important to make sure that dogs are well hydrated any time you increase the fiber content of their food, as dehydration can make constipation worse.
It is also imperative to find out why your dog is constipated. Consult with your veterinarian to make sure your dog doesn’t have an enlarged prostate, foreign material or bones in the colon, or another issue that could be an emergency if it isn’t dealt with properly.
Pumpkin is a useful and affordable way to help battle your dog’s diarrhea. If your dog is suffering from diarrhea or constipation, a tablespoon of pumpkin can ease his distress. Talk to your veterinarian if pumpkin does not help resolve your dog’s diarrhea and see if there are other supplements or medications you can try instead.
