My dog is on expensive z/d for loose stools. Can I switch his food?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Male | neutered | 2 years and 7 months old | 65 lbs

Hello- Chester has been on prescription dry dog food (z/d) for approximately 8 months. He was prescribed this after bouts of loose stool. (First we had him on this yellow powder med and it worked but once he was off that the firm stool eent back to mush) I did have him on the vegan natural balance formula before switching to the z/d. As this is very expensive, I am wondering if it would be okay to try him on a new food. Was thinking the Rachel ray zero grain dry food. Thoughts?

Hello, sorry to hear about Chester's GI issues. It sounds like your veterinarian may be treating him for inflammatory bowel disease which seems to respond to a hydrolyzed protein limited ingredient diet and potentially antibiotics if the power he was taking was Tylan Powder. You can theoretically try another brand of hydrolyzed protein limited ingredient diet and see if his stools maintain its form, however, the risk is that Chester may develop loose stools again. I would buy a small bag of the new dog food you wish to try so that if his stools become abnormal on this diet you don't have to waste a lot of food or money. Hope this helps and best of luck.
