I got a question...I am fostering a bullie puppy as of Saturday 4/16...it came to me with science diet puppy food...should I switch it? And if yes...what should I switch it to? My Cocker Spaniel is on Wellness Dog Food and he looks incredible now after being on it. He used to be on Purina One and his coat was just awful and thin. Would Wellness be good for a Bulldog puppy? I saw that Royal Canine has a Bulldog formula, but it is for adults. I would appreciate any help.
