  Pumpkin (plain, no spices) can be used to help with diarrhea or constipation.  It is not a preventative, and I wouldn't feed it unless needed. There are other things that make better treats.   
Also, if diarrhea or constipation lasts more than a day, and if you see any blood, I would contact a vet.
