Thomas Newell, a personal injury attorney who concentrates in dog bites, said the reports to state dog wardens are only the tip of the iceberg. Many dog attacks are investigated by police or local authorities. Pennsylvania does not require police to report dog bite complaints to the state Bureau of Dog Law Enforcement.
Newell said that the stringent requirements for keeping dangerous dogs, plus the penalties if a registered dangerous dog ever attacks again, deter almost all owners from seeking to have animals placed on the registry.
