I have always used the alpha role with my dogs and always will. It works and has never harmed my dogs in any way. All have been happy and healthy. Not going to stop what works now. I know it works and, as I said, mother DOGS do it to their pups to show them they are not in charge or have done wrong. Ear biting works. Taking on an alpha role works. I have used both on: beagles, mutts, bassets, dobies, rotties, chis, Am Staffs, my wolf hybrid. I also use dominant roles with Danes.
