So I've been seeing a lot High drive medium drive low drive. What exactly does it mean? How do you tell what level of drive your puppy has? My puppy was a rescue from a local humane society so he does have a pedigree and its really hard to tell anything about him other than the fact that yes he is a German shepherd. I don't really care if he a purebred or not but i would like to know as much as i can about him

he is my baby after all haha.
