Hank, our 13week old, weighs only 15lbs, and everything I read says he should be around 26lbs. We are feeding him Life’s Abundance All Stages after our breeder suggested it. He was eating it wet ok but recently won’t eat much more than 2 cups a day. Any suggestions on food or weight? Our last boxer was 70lbs and would eat anything but he was a rescue at 1yr so new to boxer puppies. Vet is not concerned yet, but I am.
