Looks like a normal chubby fuzzy yellow Labrador Puppy with me, with nothing mixed in him. He has the head of a Lab (a little blocky since he is male), the body of a Lab, the otter tail of a Lab, the coloring of a yellow Lab, the ears of a Lab, the big webbed paws of a Lab, etc.

Just because Labradors have *some* white on them does not mean they are mixed, Labradors can have some white on them when there are glitches in their genetic make-up.

If he would happen to have anything mixed in him it would be Golden Retriever, which might explain for his slightly shaggy fur.
