From time to time our furry friends get diarrhea...it happens. Be prepared. Always have a can of 100% pumpkin in the pantry. As long as your dog is not running a fever or vomiting, for those occasional bouts of the runny stuff, give 'em a tablespoon. (for small dogs, a couple tablespoons for a bigger dog) You don't have to mix it with anything...my doggies ♥ it! (Make sure you don't buy the pumpkin that's got all the stuff in it for a pie...just plain pumpkin puree) I don't know what's in it that works, but it WORKS!!! My Mags had some really bad diarrhea from an antibiotic she was taking, just one tablespoon of pumpkin and it was gone!
