I would still try it, personally. Do you know what ingredients he was sensitive to perhaps? I would just switch reaaallly slowly at first and watch for any signs that he isn’t tolerating it. Some companies will send samples of their food to you to try, so you don’t have to commit to a bag.
Finding multiple foods for him is a good idea in case there are ever formulation changes or recalls.
Some people switch cold turkey, but with his digestion issues imo a slower transition may be better for him. You could also look at adding probiotics/enymes to ease the transition, especially when you start out.
Ughhh I hate when vets do that! It’s like being sprayed with perfume at the mall. I’m actually in school for veterinary assisting and in our text book it has a chart for various diseases/conditions (ex: kidney failure, pancreatitis) and under recommended diet, every single one has some variation of Hills. Like no guidelines or anything about why to feed certain foods. The chart lasts like 5 pages. It’s insane.
