Fangless

A beautiful 2-3 year old white Alaskan Husky has a real bad habit of biting people. For a long period of time, the dog's owner tried and tried various things to get him to stop. She hired dog trainers, dog behavioral trainers, specialty trainers, etc. Nothing seemed to work. The dog maintained his biting habit. As a last resort, the owner took him to a veterinary tooth specialist who cut off the two fangs in the dog's mouth (these quickly puncture skin) and filed the rest of his teeth down so that when he tries to bite, he can't do any damage. After all this, the dog still has the bad habit. Do you think this is cruel by going to the extreme when all else has failed?
