Here is a video that shows that Pit Bulls do not have the strongest bit and you will notice that the pit bull does not hang on any longer than the other two breeds tested. http://www.youtube.com/watch?v=R7jhrxy0HKs&eurl=http://www.rottweiler.net/forums/general-info/74918-true-bite-strength-rottweilers.html
When you look up specific breed kennels/ breeders you will find there is more kennels/ breeders listed for Pit Bulls than any other breed. To me this shows there are more Pit Bulls owned than any other breed so I would expect to see more attacks by Pit Bulls than any other breed. Just as if there was more Boxers, Dalmatians, Border Collies, etc... owned than any other breed I would expect a higher bite rate from them than any other breed. I believe banning a breed would never lower the dog bite fatalities. The only way to lower dog bite fatalities would be to seriously reduce the number of irresponsible owners and educate the public on dog safety. Or maybe it would just be easier to ban all dogs over 25 lbs and while we're at it outlaw driving since more people die in car accidents than dog bite fatalities (Motor vehicle crashes Deaths per year: 43,200), or how about we ban guns since more people have died by a gun than any dog bite fatalities (Firearms Deaths per year: 1,500), or how about banning fishing, swimming, or taking a bath since more people have died from drowning than any dog bite fatalities (Drowning Deaths per year: 4,000)? Does that seem a little silly to ban all those thing? Well so does banning a breed of dog!
