Good idea and in the UK, shoot the owners as the kind of dog is only kept by the retards that the UK is breeding quicker than the dogs. The dog we are talking about here at the moment is the American-interbred thing that grows to 9 stone, interbred to be vicious and a potential threat and killer by nature.
On the forums, folk are posting a person could do this and do that, split its legs, spray it, choke it or hit it with half a brick, should any of the victims be strong enough or happen to be carrying such objects?
As a young child, I had half my face torn out by a small dog, missing my eye by a gnats whisker. Never made me frightened of dogs, but on some days the scars could still just be seen when I was 50 years of age.
My BIL was a Police Officer in charge of the Police dogs. Big guy and tough with it, having been in the boxing ring with some household names. One dark evening he was attacked by a huge guard dog while patrolling a building site and ended up splitting the dog's legs open. He left it there and did not report it, as he did not want the grief and paperwork.
Seems obvious that 99.9% of the public in the UK would not stand a chance in hell against a creature that has no place existing here, a Frankenstein monster bred for lifes knuckle draggers.
