A father has described the moment his 6 year old daughter was attacked by a Staffordshire bull terrier. He said the attack was something he and his family would never forget. The owner of the dog has admitted in court that the animal was dangerously out of control. Do we need to ban more breeds of dog? Should there be tighter controls on who can own which breed of dog? Should all dogs be muzzled in public? Do we need tougher laws on dangerous dogs?
