I think they also have Wellness CORE (grain free), regular and fish varieties (I know Petco does, but I think Petsmart does, too). Their fish canned variety is practically the only commercial food that doesn't have something B shouldn't eat.
I'm sure they also have freeze dried treats, especially liver. And bully sticks (overpriced). That's about all I can find for treats for Bales, but he doesn't get any grains or poultry.

Whoops, sorry if my post wasn't relevant.
