Would be hard to eradicate the problem gene now because pits owners often let their dogs out to roam or the pits defy enclosures and leashes and cross breed at will - thats why deaths are often attributed by “pit mix.” Some don’t look much like pits but they have the instinct.
And then pit apologists selectively breed some pits to look like Rotties. There was a news story about a “service dog” rottweiller that went crazy on a bus and maimed some people. A closer look at the story revealed the “rottie” was an adult 40 lb dog. So the rottie coloration was used to pass off the pit bull and of course the “service dog” story was yet another lie.
Many medium to large breeds have a history of trouble. But there’s a particular problem with the American Pit that’s occasionally devastating, but hardly quantified.
Just having a hard time with the blanket condemnation of American terriers. And I’m saying this knowing what’s required to keep and maintain an aggressive canine.
