Canned pure pumpkin is great when need the help settle their stomach. I think a few weeks ago there was a thread going around and some posters had pics of their dogs playing with gourds and pumpkins. Good point about seeds....not sure on that.
Those lil pumpkins are pie pumkins. Pumkins are fine in moderation, most dogs won't eat a whole one. My dogs had a blast playing, rolling the pumkins around. They chewed, shredded destroyed them more than ate them.
