Diet change and Puppy has runny stools
I picked up Saxon two weeks ago from the breeder .Over the last week i slowly changed his diet from Purina Puppy Chow ,which the breeder gave him,to Victor all life stages and puppy. Since yesterday he is on all Victor and now has runny stools. He is happy ,active and no problems otherwise. Do I change him back to puppy chow ? He was eating 2 1/2 cups puppy chow and now eats 2 1/2 cups Victor. Is it maybe too much Victor since it is a better food?
