Two Pit Bulls recently attacked an Urban Search and Rescue K-9 in NC. The K-9 later succumbed to the injuries. These PB's accessed the K-9 over a 5' chain link fence while running at large from another neighborhood. The loss of the USAR K-9 while tragic on many levels would have been nothing compared to the loss of a human life. Side note: The neighborhood where the K-9 lived has 20 children under 12 years of age. The owner of the PBs is in trouble, as are local authorities. Reportedly these PBs had attacked three times previously and no action had been taken to prevent a re-occurrence. All "wild animals" don't live in the woods. Be prepared to deal with these type problems, both mentally and physically, if you could be faced with this situation.
