If you are looking for grips, stability, work ethic, athletic ability, drive, structure and energy, this is the litter. Both Mac and Chaos have huge grips, and are very forward in the protection, regardless of the pressure being put on them. Very confident dogs, socially and environmentally. Both of them jump maximum on the FR hurdle, quite a feat for Chaos considering her smaller size. And their pups inherited these traits. Medium sized, with a few larger ones, very handler oriented with a lot of energy and go, go, go when outside working, but they can come into the house and turn it right off, settling down for a nap or to play with a toy.
