Thank you. GE is the most athletic then PB, Little Secret, then SuperStar. Even though GE is very athletic, at times when he just wanders around he looks a bit clumsy. But once he works, he just snap and go all out. He has wind for days and a crazy mentality so he never tire out or stop. PB is a total package, he is always in control, very intelligent, and when he grab on to something, you either have to pry his mouth open or choke him out of it. That dog could keep his mouth shut. Little Secret is as athletic as PB but she can't control her movement.(very intense) And run hot. We looked at her and she passed all her test. She's got mouth, very skilled defensive game bitch who will barely get touch for the first 30 minutes. Then she'll slow down and run hot and be the down dog but always holding onto something. We decided not to campaign her and keep her as a brood bitch because she's too valuable. As for SuperStar, he is the least athletic out of them but for his size(26lb)condition, i doubt any little dog could stand a chance against him. He's a smart defensive dog with mouth and who'll barnstrom and punish his opponent until he gets tire and by the time he's through, their mouth and nose are pretty much smashed already. And unlike his sister, he's got natural wind. He is also game to the bone if he has to go the distance.
