I am not a lawyer and this is not legal advice. But if I was an owner of a dog who has ever bitten someone, I would want to be totally familiar with Act 426 of 1988 “Dangerous Animals”.  As I read it, if your dog has bitten someone it is now classified as a  “Dangerous Animal” and can get you convicted of involuntary manslaughter if it then kills someone and up to four years imprisonment if it seriously  injures someone. This law is posted on the Township Website Sheriff’s page and here:
