Did you even read the article? There is so much mis info in that..
They are not Staffies, and that white dog is NOT a Bully Kutta. And I doubt that the brown dog is a ridgeback-bully.
Dude probably says that they are those dogs because Pits are outlawed in the UK, correct?
So, surprise a dog aggressive breed that probably doesn't have the training nor has Ben acclimated to being with other dogs causes havoc and attacks and mauls another dog.
Good point, the white dog looks more like a Dogo Argentino than a Bully Kutta:


And there's nothing ridge back about the brown one, it's a "pitbull" type dog and he's mislabelling them so he doesn't go to jail as these breeds are banned.
He's lucky the day they snapped they snapped on an innocent Beagle, his daughter could have been the victim and in the video he clearly has no control over them and he gave up and walked away.
