lamb can be hard on some dogs, chester cant have it now he gets diarrhea, how long was he like this at the breeder and did all the dogs have it. Its best to keep them on the same food for a bit and then do a slow change over but sound like he is having problems already. I would make sure hs stays hydrated and keep some nutrical on hand in case he gets low blood sugar, I would probably do bland food, what did the vet say |
