3 Pa. Stat. § 459-704
If the identity of the owner of the dog or dogs has been established under section 701 or 701.1, the secretary may notify the owner or keeper of such dog or dogs to immediately kill it or them. It shall be unlawful and a violation of this act for the owner or keeper, after notification by the secretary, to allow to leave or to remove such dog or dogs from the premises, while they are alive, except to a State dog warden or to a veterinarian or animal shelter for euthanasia purposes. The killing of such dog or dogs does not remove the liability of the owner for damages caused by the dog or dogs. Upon failure, however, of such owner to comply with such order within a period of ten days, the secretary may authorize the killing of such dog or dogs wherever found. In addition, upon failure of such owner or keeper to comply with such order within a period of ten days, the owner or keeper shall, upon summary conviction, be sentenced to pay a fine of not less than $100 and not more than $500.
