I don't think lab, but thanx for the info about waiting untill he is 6 months of age. I never knew that before but now that you mention it, it does make since. I do think that he may have a little bit of pit in him. I think they are pritty much the most popular breed in america and they are ALWAYS in the pound when I stop by. I also think that what ever his parents are, they may have been bred on perpose because of his docked and he was brought in alone and the workers told me that the person who brought him in seemed to know the exact age so they think that maybe they just told them he was a stray so they wouldn't have to pay a fee. Saints really arn't that popular around here but there are some around... It's just so hard to tell what he has in him because some dogs that are mixed, you can't even see some of the breeds that are in them
