All feed is the high energy dogs all look good and stay healthy. When I raise puppies I'll feed the diamond puppy for the first year and they will stay fat as hogs! I have tried other brands and they will keep your dogs alive but to me they just don't look as good as they do with the diamond dog food.
I like the Diamond puppy food Harley, but it is 30% protein. Protein is good, but have you ever seen what excess protein does to a puppies joints? This is the only thing that worries me about the Diamond Puppy food.
