Note 5 — Penal Law
Reading edition
If a dog runs out threatening to bite a passer-by, and the latter kills it, he is required to pay the value of the dog. If a dog bites a passer-by, the latter may kill the dog and need not pay a fine. If the dog bites him, and he does not kill it, he may demand a payment from the owner. It was a provision of primitive Roman law that “If an injury were done by a slave, the person injured had the right to exact vengeance against the slave personally, thus injuring the master’s property; and the master or owner was consequently allowed to prevent this vengeance by making compensation for the injury done.”5
