The problem of dogs biting people and fighting other dogs is getting worse. Every year, the NHS dog bite figures increase; court cases for dangerous dogs are at an all-time high; the government is still failing to tackle the issue of “status dogs”; postal and other delivery workers and assistance dog users are demanding protection; and behaviourists’ case-loads are full of biters and fighters. Whatever happened to man’s best friend? No sensible person wants their dog to bite them or anybody else, or to fight with other dogs, so why is it happening on an unprecedented scale?
