I have a Lab Mix,What's the mix?

He's 5 & only weighs 60 lbs.He doesn't have web feet,He has a flesh colored nose,his underbelly is pink & very soft so is his hair.He can scale rocks & the sides of hills like a billy goat.He looks almost pure Lab but he has a bushy tail? Here's a 10 second video of him.a href="http://www.youtube.com/watch?v=GY8bTY9wJfs" rel="nofollow"http://www.youtube.com/watch?v=GY8bTY9wJ…/a
