Border Collie tries to climb tree

Jack is a two and half year old border collie with unlimited energy. When he isn't running around the farm, checking in on the other animals or playing fetch with anyone he can get to play, he likes to climb trees. There were no birds or squirrels in the tree when this video was filmed, but that doesn't mean there wasn't one a few weeks or months ago and Jack is now on a mission to climb up there and check things out for himself.
