I’ve never fed Canine Caviar, but know of some people that have, so hopefully they chime in when they see this.
I’d never feed Taste of the Wild as it is a diamond brand.
Natural Balance is A. Owned by Del Monte so that is questionable for sourcing and ingredients, and B. Low in protein for my liking
Timberwolf looks pretty nice, but I’ve never used it, it’s not very available to me, I believe they are severed from Diamond at this point?
Addiction is on the low end of protein I’d feed, but haven’t honestly known of anyone who feeds it.
So, my answer: The two widely available foods (Nat Bal and TotW) I won’t go near, the other three are all a bit less common, so I don’t have a lot of experience there. But there are many other grain frees I do recommend
