The Bureau of Dog Law Enforcement within the Department of Agriculture oversees the Dangerous Dog Registry and Enforcement. Each county in PA should have their own dog warden. They are tasked with investigating any claims of dog attacks, identifying if any of those dogs may be dangerous, and if so, bringing charges against the dog owner. When a dog is deemed dangerous by a Magisterial District Judge, dog wardens oversee the registration of the dog to the Dangerous Dog Registry, and inspect to make sure the Dangerous Dog owners follow the statute.
In 2017, PA Dog Wardens recorded over 1,400 dog bites. This does not include police reports or other animal control officers so there were probably more dog bites than the above number in Pennsylvania.
