| Seriously? Find a new trainer! Good heavens, I can't believe that in this day and age "trainers" are telling people to roll a dog. I'd seek out one who knows dobermans and can actually help you. The sex of a doberman really doesn't matter in the whole scheme of things. A female could behave exactly the same way and give you just as much of a hastle.
Stop rolling that poor boy and start calling around to different clubs to find yourself a good trainer who knows the breed. (sorry if this post seems blunt)
