Well bred little guy you have there. Half brother to 4 time World Champion rope horse! In all honesty, Blue Boy Doc breeding is pretty normal up here. Greg lost him just last winter and until then he was still covering mares at 29.
The Bugs alive breeding is running blood. A bunch of the barrel horses go back to this. Smarty Glo was a pretty good little horse if I remember correctly. And of course lots of Doc Bar and King breeding.
Once he builds up some muscle he should somewhat resemble a tank.
