As of 2018, about twenty-three (23) states have laws that limit or otherwise control how owners can tether their dogs. Tethering or chaining a dog under most state laws means that a person ties a dog with a rope or line to a stationary object. While the laws themselves vary from state to state, they do have several consistent features. Some laws that address tethering allow a dog to be tethered for a reasonable period of time. Other states include tethering as part of their anti-cruelty chapters. Indiana defines “neglect” as restraining an animal for more than a brief period in a manner that endangers the animal's life or health by the use of a rope, chain, or tether. Some states specify the manner in which a dog must be tethered or chained (i.e., that a tether must be at least 6 feet long or at least 3 times the length of the dog as measured from the tip of its nose to the base of its tail).
