It helped Cody. she had many many bouts with gastritis, colitis, pancreatitis, etc and I used Prozyme with her for years on her food. If they don't eat their food right away, it'll turn to absolute MUSH though!
She did have firm poos once I got her on a food she wasn't allergic to AND used Prozyme... if you get it online, in the larger bottles, it's LOTS cheaper than from the vet!
