Dog owners in Pennsylvania are required to maintain control of their animals at all times, meaning that they must use leashes, collars or other devices to prevent them from straying when in public. Some dog owners disregard leash laws and refuse to restrain their pets. Unfortunately, unrestrained pets sometimes attack people – including small children. When such attacks occur, they can be terribly frightening, physically damaging and painful. According to state law, when a dog bites or attacks someone, its owner is liable for any damages.dog bite attorney pennsylvania
