Bullcrap. Dogo Argentinos are were bred for HUNTING, MILITARY USE, AND POLICE USE. They are NOT for "pets." That's why they're banned in the UK, punishable by 6 months in jail or a 5,000 British pound fine. Thank you, Wikipedia. Also note that they're banned in Aurora, Colorado and are notorious for their aggressive temperament, just like one of the typical Pit Bull breeds. Hell, they even look EXACTLY LIKE pit bull, but if you want to act like a freakin' deluded smarty pants, then go ahead. They should be banned like any OTHER pit bull and I don't give a damn about their exact lineage. They're NOT PETS.
You're obviously overwhelmingly biased towards certain breeds of dogs. Have you considered that you might be missing some information? Since you've proven you can research on the internet "wikepedia" I highly recommend you do a search for pitbull placebo pdf. Might enlighten you to the real story behind "vicious" breeds.
