We are new to the site. Just thought I would share some information. My 8 month old French Mastiff had the runs, took her to the vet 3 times and they cold not find anything wrong with her. Someone suggested to me pure pumpkin out of the can, not the pumpkin pie kind just plain old pumpkin. I gave it to her at night and the next morning she had a normal stool, it was so great that it worked so fast. The vet had given her 4 different medicines and nothing seemed to work. There is nothing that can hurt them it has lots of fiber and Vitamin C. Love the site, glad I found it.
