Work in hidden protection.
No great mind is needed to teach a dog just to bite. It's important that the dog should be managed even in independent work. An uncontrollable dog, that was taught only to bite, at the moment when it's needed is in its kennel as a rule, as the owner isn't sure of it. One can be deprived of the dog if it bites somebody. So use of the dog's teeth is an extreme measure.
Very nice work - I had Bouviers years ago and miss them. Where is this dog from?
