First, this site is addicting. Okay, here is my question. I have a 8 month old Chi. At least I think he is 8 month. Well, the orginal owner was feeding him food that wasn't good for him. I have the dog now on Royal Canin. Is there something else I can feed him to fat him up..well at least put somemore meat on. I know Chi's are pretty slim, but you can kind of see Chi Chi spinal. I also let him free feed.
