Hello all, I recently got a 13 month old razors edge male. He's very playful and active, my little shadow lol. Anyway, he just a tad bite under weight and was being fed diamond adult. I feed my dogs Kirkland and I am wondering 1. Is Kirkland a good brand (I know its the diamond equivalent) 2. Should I feed him the puppy formula for a little while? 3. I used 2 give my dogs raw beef marrow bones but have read that knuckles are better, which do you all prefer/suggest?
