It's been the problem here in Bristol for at least 10 years.
If you visit the dogs home you can guarantee to find whole litters of these.
Often they are not identified as Staff crosses to make them more appealing.
My good friends cousin has one that was described as a puppy as a Lab cross. If the Police were very into enforcing the DDA hers would fit into 'Type' quite easily, large muscular and Red and white.
