If you look at past history these things usually, but not always , follow the latest craze for hard men dogs. Years ago it was Alsatians, then Dobermans, rotties, and the list goes on. You get the dicks who in breed the dogs to sell for profit, and they then sell them to more dicks who have no clue on how to look after the latest hard man accessory. The dog goes on to attack some one and the poor bloody animal gets put down. Then the dick gets another dog and the cycle begins again. Put the dick heads down instead.
