Im alil concerned after reading as Dexter is about to be 6 months and just weights 35 pounds, we live in Belize CA so our dog food choices are limited, rite now he is on Purina Puppy chow complete he eats 2 cups twice a day with a snack most afternoon something healthy like a carrot or frozen cube steak.. new doberman owner so would gladly accept any tips, a friend of mine (he has 2 pitbulls) suggested i give him some vitamins named Bullymax, I'm hesitant as the name in itself doesn't sound all that convincing almost sounds like steroids.
