+3 taste of the wild high prairie, nothing but. I don't have a Pitt but I do have a 110# Doberman than is super active and super healthy. He has no health issues what so ever. He chases my 2 year old blue heeler around like he's still a puppy. Did I mention he's 13? For all the non dog minded people reading average lifespan is 8 to 10. His coat is shinny and he passes up treats for taste of the wild.
