Hill's Prescription Diet Gastrointestinal Biome with Chicken

My dog seems to have an allergy, but unfortunately, it’s not possible to tell from the declaration of this food exactly which proteins are included… so for us, the search is really just beginning. He came to me with constant diarrhea, and even after 6 weeks, this food didn’t help—in fact, it actually made his terrible gas even worse. After just a few days on a different vegan food (since now we have to figure out which proteins he can safely tolerate…), the problems disappeared.

Two years ago they were €58 for 10kg. They've gone up by €20, so it's really expensive now, even though they work well. Making homemade ones would save a lot and probably be better quality. I think this will be the last time I order.
