Does anyone have ant experience with this breed? I understand they make great protection dogs, smaller than and not as aggressive as a German Shepard. They are supposedly high energy and train very easy. They, along with the Belgian Malinois are being used a lot in police work in place of the German Shepard so they must have something going ffor them.
I lost my old German Shepard after 14 years and am looking to replace him with another dog that will serve as both a pet and protection dog………..one that leaves his mark on the butt of an intruder when I am not home.

Give me your experience with them.
