My 1 1/2 year german shephard puppy eats his dry dog food, only when I mix cooked hamburger into it... Do you think it may be the brand (Pro Plan Adult) that he does not like? I've tried some other brands and it doesn't set well with his system. Do you think I should try some other brands as well?
Sure why not. Or you can just continue with the hamburger. Good luck, vetcare
