Safe to share · Dogs · full breakdown on the linked food page
Safe and useful — plain canned pumpkin helps both constipation and mild diarrhoea. Not pumpkin pie filling (has sugar/spice).
Short answer
Yes. Plain canned pumpkin is safe and can help with both constipation and mild diarrhea in dogs. It must be 100% pumpkin, not pumpkin pie filling, which contains sugar and spices that can upset your dog's stomach. Feed only small amounts mixed into regular food, and call your vet or the ASPCA Poison Control line at 888-426-4435 if symptoms worsen or don't improve within a day.
