Jasper is a 70lb black lab that is full GO.  From a puppy this dog has been the easiest handling dog as he wants to please and is on a mission to retrieve.  He is very much ball driven, which means his reward is action he never needed praise to take a command.  Take a look at his pedigree and you'll see he comes from a long line of field champion dogs.  It's hard to surpass the bloodlines in this one.
