When we brought Emma home the breeder had her on Royal Canin food for large breed dogs 5 month to 15 months. Since she was eating this we just have left her on it. But while reading the forum I have realized her Food is wayyy important. I have asked for advice on an existing thread and no one answered me. Anyway, should she be on age appropriate food? Is Royal Canin good for her? If I have to ween her another food, how do you do it so her tummy won't get out of whack? Thanks.
