Keeping a dangerous dog

In plain English

If someone owns a dog that has already bitten a person or another animal before (without being provoked), and that dog bites someone again, the owner can be charged with a crime. How serious the charge is depends on how badly the person was hurt — ranging from a misdemeanor up to a felony if someone dies. A dog involved in such biting can be taken away and put down, but the owner can go to court to try to stop that. If the person who got bitten was in the middle of doing something illegal at the time, the dog owner is not in trouble and the dog does not get put down — though this does not apply if the only thing the person was doing wrong was simple trespassing, or if the trespasser was under 12 years old.

Penalties named in this law
