The list is endless. We are now seeing flock protection breeds like the Caucasian Shepherd and the Central Asian Shepherd where I live - they make an XL look like a staffie. The issue is two fold - dealers (for that's what they are) who don't give a toss, and customers who don't care enough for their dogs to learn how to be a responsible owner. Ban the XL, they go for a Presa or a Cane Corso, or an Akita, Ridgeback...Yep. Ban the Staff/Bully/Mastiff breeds and crosses all you want, all the way to French boxers and bulldogs, you'll just have people on here giving out about GSDs and Labs in a couple of years demanding they be banned as well.
