The GMP has helped my dog with the occasional diarrhea. She seemed sad and not very active, which I just thought was because she was over her puppy years. Managing other issues, my Internal Medicine Specialist Vet suggested this and believe it or not, my dog was not over her puppy years yet. She is happy again, she's active, she plays a lot. Stools have improved. I can't be more thankful. We're on this for the long run.
