I just got back his dna results and we knew two of the breeds to be in the mix, the third is quite the surprise. Reading up on all the traits of the three breeds makes me realize he is the combo of all three. I'm posting his 'lineage' pic so as not to spoil the big surprise (well, at least to my friends and neighbors who all took a guess at his breeding) it's a surprise.
Must be a shadow but there's no beard. He has a very labby face and body but he's tall and long. He'll fetch the ball like a lab but then keep it like a shepherd , all at rocket speed like a borzoi. I love my mutt.
