actually, if he is mix, as it appears he is, he can show more of the retriver body (which he does) we had a dog once that was Shepard/chow/lab mix, and the only thing chow on her was her tounge. she had this short hair coat, very thin body, and had silver markings on her black coat (I miss that dog).....I would help you out if I could, but as I said, I can not have pets here, and even if I could, if he is that active, I do not have room for him
