In early 2013 my dachshund, Rudi, was attacked and nearly killed by a neighborhood dog, with no provocation, while being walked along a local trail. Rudi required emergency surgery to repair a bite wound to his thoracic cavity. The vet bill was in excess of $600. I have heard since of other dogs in our neighborhood attacked and seriously injured by this dog. Nevertheless the dog continues to be walked on a loose leash and without a muzzle. My attempt to have the dog declared dangerous was not taken seriously by local authorities despite my warning that a child could be this dog’s next victim. Any dog that has bitten and seriously injured a person or other animal must be deemed dangerous whether they've ever shown vicious propensity or not, and steps must be taken to prevent them from attacking again.
