Have fun with your new puppy. I had a boxer/lab mix that grew to 80lbs! He was a male too. Please have your new pup neutered. It does prevent a lot of problems. He was quite a dog. We had a summer home in NH on an island. The kids used to play hide and seek after dark, and we used to fight to see would have "King'. He had the nose of the lab I think. Good luck .
