I've been feeding my 6 month old corgi Purina Puppy Chow and he loves it. But I feed my 3 year old corgi Purina Dog Chow and she is very, very slow to get it down...I don't think she likes the taste of it. (She'd rather have the puppy chow but my vet said no to that.) I add a little beef broth to make it more appealing but she still doesn't want it. I'd like to buy her food that actually tastes good and is good for her. Any suggestions?
