In my opinion, the root cause of most of these cases seems to be the worrying trend towards owning these dogs as accessories, and as weapons. Because of the demand for certain types of dogs for such purposes – primarily on inner-city housing estates – there has been a huge increase in dog breeding for undeclared profit. As a result, we are seeing a lot of puppies who are diseased due to poor breeding. The number of dogs being dumped is at an all-time high, and Battersea Dogs' Home can no longer take in Staff-type dogs. The problem is seriously out of control.
Fortunately, in our more rural area, things haven't reached this pitch, but there's still a huge problem of irresponsible breeding of Staffordshire and other bull terrier dogs.
