First there should be exceptions to when the dog IS allowed to threaten or bite, which would be considered provocation... those would include: a.) Legitimate self defense; b.) Defense of territory; c.) Defense of pack — human family, other home pets, and such; d.) Establishment of a reasonable pack order within the home; e.) Mouthing (which is not the same as being
aggressive); f.) While being trained during lessons, and in the midst of long term maintenance training, to teach a dog to contain it's
drives and aggression; g.) For legitimate police work — if a police force obtains ownership and control of the dog, then the court order should be rescinded and the dog be given a fresh start; h.) Legitimate
hunting purposes (such as duck
hunting).
Despite the fact that Great Danes were bred as
hunting dogs, they don't generally show a high prey
drive, and they aren't prone to an
aggressive disposition.
