Hi,
I'm not sure - but our Jack Russell Terrier, Agnes, has been having a real tough time with diarrhea - throwing up -. Since she will be 17 on Dec 3rd we thought this would probably end it for her.
Then I went on line and read that regular old canned pumpkin - NOT the kind that has spices in it for pie making. Has made her almost 100% well again. It is amazing. When we started with it I would put 1 tablespoon in her food 3 times a day, (These were small meals.)
In a few days she was up and running. I still put about 1 tablespoon in her dinner.
Good luck!
