Our dogs used to be on a dog food that receives mediocre reviews, but they did really well on it. After some research, I decided to put them on food with much better ratings, but my collie just isn't doing well on them. A couple of high quality foods gave her terrible digestive problems and, whilst that aspect is sorted now, she has started developing skin problems, which she never had in the past. I don't know if it's related to the food, but it seems odd.
Is it possible that some dogs do better on food that is apparently not as superior as some??
Thanks for any thoughts!
