There are some 53 MILLION dogs in the US.
Bully breeds make up 30-40% of those dogs. So, 21.2 MILLION on the high end.
There were 42 dog bite fatalities in the US last year. 27 of them "pit bulls".
So, you had a 1.27 * 10^-6 chance of getting killed by any particular "pit bull" last year.
Even if my numbers are off by an order of magnitude..... yeah......
Same question to you , have you ever been around one of these dogs and if so were you attacked, or are you just posting stats off the web ? Again reread my post and enlighten yourself, before you judge...
