I've heard complaints that some dogs get fat on Black Hawk. We're using it for treats at the moment and my dog loves it. But she's not particularily fussy.
I also feed my own home made wet food that contains mince cooked with veg (carrot and sweet potato), brown rice, bran, oats and sometimes I add some calcium powder which one of my vets says is not needed since she gets dry as well.
I think the note on the black hawk just says to feed more of it to puppies or pregnant or lactating bitches.
Evil hound says it's time for a walk.
