what i also noticed one time and I realized it again with that butt picture of ziris lol is seems like Dobermans have two different shape marking on their butt...either its a circle shape...or some kind of boxier shape with some edges....has anyone else noticed that?
When duchess was at dog training I noticed Duchess has the boxier shape tan marking on her butt...but some of her brothers had really defined oval or circle shapes...lol
