It's hard to say if that pup is a full blood or not. I've seen 5mo olds that had that look. Different bloodlines can look differently at that age. My reservations are this... no long guard hairs visible, I wouldn't expect a lot of them since he is in a hotter climate and only 5 mo but he should have some. Also he does look smaller than you would expect at 5 mo. but it's difficult to say with nothing to compare him with for size. Things that look correct.... Head shape is correct, ear set is down where it should be in the last two pictures (the profile and the one to the left of that), mouth shape is correct. The only thing that concerns me about wether he is a full blood or not is the coat, and being from a hot climate you can expect to see that this time of year..Jackie
