I love pitbulls but sadly they are banned in the UK and BSL is making lives of anyone who owns a dog that is the same size as a pit a complete misery. Dogs are taken based on their looks and measurements and are confined to sparse kennels until their court date (which could take weeks) and the outcome of court could go two ways. The dog is released back to its owner but has to be neutered, tattoo's and muzzled at all times, the alternative is that the dog is put to sleep. Most of these dogs have done nothing wrong except look 'pit type'. I have owned Staffordshire Bull Terriers for 20 years and cannot fault them, they have been great with all people and children and of the 4 I have owned one hated other dogs.
Any dog can be aggressive - deed not breed!
