My son had his dog, of questionable parentage, checked by a company that checks dog DNA. She looks a lot like a yellow lab but then not. Hair is much thicker, white blaze, head a little wider. Just several things that don't line up with a lab. The data came back that she is 1/2 golden retriever, 1/4 bull mastiff, and 1/4 some kind of terrier. I don't have a clue what kind of dog she is and don't know if that company took my son for a ride or not. It really doesn't matter though because she has been a great dog. I have always had more trouble with pure bred dogs than mixes.
