By that argument we'd be banning German Shepherds, Great Danes, old English sheepdogs.........
Banning XL bullies will mean an increase in those people who currently irresponsibly own them, irresponsibly owning Dobermans, or Rottweilers, or Alsatians.
And yet, we’ve had significant populations of those breeds in the UK for decades without the quantity of deaths and life-changing injuries that are being seen from the recent and numerically insignificant extreme bull breed population.
I don’t think it helps anything to deny that there is an issue. The usual suspects will be along soon though, to say what a wonderful breed they are in the right hands. Perhaps that’s true, but if that’s the case there needs to be a way to restrict them.
