The Scottish Society for the Prevention of Cruelty to Animals is extremely concerned about the situation that is arising. Pit bull terriers and rottweilers are very numerous in many tenement properties and in some multi-storey flats. Tenants are terrified to go into some lifts, and parents do not like to send their children into the parks, where these animals are let loose. I understand that Strathclyde police officers have been injured because drug dealers are using these dogs as a front line of defence. Surely the Government should introduce legislation to outlaw breeds that are dangerous and have aggression bred into them.
