Dear Sir, Recently my son was attacked by a dog in his friends garden. (They had recently purchased the dog second hand) my son and their son were left alone in their garden with the dog. My son underwent two operations and will live the rest of his life with both physical and mental scars. He wakes up screaming thinking the dog is ripping his arm off. The police are reluctant to push a case due to the dog/children being unsupervised, as the dog was destroyed. I need to raise awareness so dog owners realise you can never trust a dog 100%. We need responsible dog owners and If it had been supervised my son may have been bitten but not to the extent it was. Angela Kennedy
