ok here it goes, i had adopted an 11 mths old dog from the pound, he was abused and neglected. to me he seems a little bit on the skinny side. but not much. hes already 52 lbs..now my question is, is it too late for him to develop properly? i mean, i am still feeding him puppy food. he is now 12 mths old. should i start with adult food? or can i keep giving him puppy food. will the nutrients in puppy food restore what he had been missing out on???? meaning, will his bones get bigger etc..
