Tethering law

A state or local law that limits how and how long a dog may be tied or chained outdoors, to prevent neglect and injury.

Also called: anti-tethering law, anti-chaining law, dog chaining law, tie-out law, tethering ordinance, unattended tethering, chain law

A tethering law limits the practice of tying a dog outdoors with a chain, rope or cable. Rules vary, but common ones set a maximum number of hours per day, ban tethering at night or in extreme weather, require a tether of a minimum length and a lightweight design, and some ban choke or pinch collars for tethering. Some places ban unattended tethering altogether. Many US states and a larger number of cities have such laws.

The rules aim to prevent neglect, injury from tangling and aggression linked to isolation. Many animal welfare and veterinary groups discourage keeping a dog on a tether as its main way of living.

A tether is different from a leash law, which governs control in public. A fenced yard or a safe dog crate or pen, when used properly, are common alternatives. Ask local animal control for the exact rules.
