i've seen documents of fighting dogs. And everyone almost uses pitbull in america because they are much more easily available than in other countrys and ofcourse damn athletic. And all the owners explained the same reasons as E-kul... the look, the feeling of being powerfull and feared etc, a macho thing. And they are used all over the world too because they are very agile specimens of dogs. Big dogs are useless in dog fights, they prefer small, agile and strong,- that's pitbull. More for the money
But the dogs didn't ask that kind of attention. Man made the image because it fitted to their own world views of power and show off and insecurity... and sickness.
The dogs who are attacking people on the streets, every single time their owners get in the video tape by the newsreporter the owner has allways been some weird looking anti social #### who hates everyone and is insecure, and definetely doesn't take good care of the dog and gets self esteem through the dogs fearfull acts.
