I appreciate the feedback. Spray would probably work in many instances although I believe I would not trust anything less than Bear Spray. Once a pit bull has you in it's grasp I don't believe anything less than a 9mm will fit the bill to stop that attack. I have to modify my statement about "large dogs". I have never read or seen where a lab or Australian shepherd or other such dogs known to be pleasant, attack and injure someone severely. I'm sure it has happened. The facts are, pit bulls, German shepherds, rottweilers and chows are responsible for almost all serious injury and deaths caused by dogs in the US. These animals are born to attack and even when raised by caring owners are known to attack and even kill humans. It is in their genes just as bird dogs are born to point and rat terriers are born to squirrel hunt and sheep dogs herd sheep. I would argue that lions and tigers can be trained not to kill and are used in shows and even kept in homes. If, however, you believe that the natural instinct of lions and tigers can be totally removed by a caring owner, you are putting yourself and others in danger. Just ask Roy Horn. Here are the facts. [In 2010, the combination of pit bulls (22) and rottweilers (4) accounted for 79% of all fatal attacks. In the 6-year period from 2005 to 2010, this same combination accounted for 71% (129) of the total recorded deaths (181).] See that number? 181 deaths. These were mostly children and many were children of the dog owners. Google "dog attacks in the US." These dogs only account for about 5% of the dog population in the US but make up almost 80% of deadly attacks. I have personally known 2 women who had terrible scars on their faces because they were attacked by dogs when children. No, it wasn't beagles or dachshunds...they were pit bulls. The response of the owners in both instances, "They have never done that before." Ask yourself-Why don't the police, rescue and military use pit bulls? One human life, one child is more important than all the pit bulls in the world. I'm sure someone will disagree. Facts are such pesky things.
