Well, if your vet said that it'd be okay to feed him lamb and rice dog food, then any kind of lamb and rice brand would be okay for him I think.

There were a couple threads a week or so ago about different dog foods. I learned that the kind with meat as the first ingredient are the best - and at my supermarket that's only Iams or Purina One. So if your mom won't go to a petstore to get Jasper's food, then those would be my reccomendations.

But I think that some lamb and rice brands might have other kinds of meat in there too - so if he's really sensitive you may have no chioice but to get a special brand from the pet store.
