Dobermans are notorious for that crap too. My 4 year old male Dobie is quite overbearing and pushy.Even if you succeed, you will have to endure and survive the ritual challenges of the next-in-line alphas. We raise Lhasa Apsos, which have a high incidence of alpha traits because they were bred to be autonomous temple watchdogs. These little suckers are always challenging us for dominance.
