Leash

A leash, also known as a lead, lead line, or tether is a rope or similar material used to control an animal by attaching it to a collar, harness, or halter. In British English, a leash is typically used for larger animals that may be dangerous or aggressive, while a lead is more commonly used when walking a dog.

Leashes take many forms; for example:

There are also bicycle dog leashes, especially designed for people who enjoy taking their pet on a ride with the bike. The leash is an aluminum tube with a plastic coated cable which runs down through the tube. It extends out of the tube end a couple of feet to allow for ease of movement for the dog. One end connects to the bike and the other to the dog's collar. This keeps them safely away from the bike. While bicycle leashes might be suitable for some dogs, they aren't a good idea for all breeds. There are numerous safety considerations before attempting to bike with a dog.

Cat leashes and harnesses are also available on the market and are convenient for people who are not comfortable letting their pet free.

Many cities have passed legislation that requires dogs to be on leash in public areas; in some areas, cats are also required to be restrained (under control) on a leash, in a kennel, or in a cat-proof yard or house.

Purposes of a leash include: preventing animals from frightening or biting people or other animals, defecating and urinating in inappropriate places, endangering traffic, digging up lawns, causing other damage, getting lost, and getting away from owners. Leashes also provide a clear method of communication and ensure control during training of dogs.

In the United States, leash laws are different within each state. While some states do not have statewide leash laws and give localities power to make leash law, there are some other states in which leash laws apply statewide.

States that do not have statewide leash laws are Alabama, Alaska, Arizona, Arkansas, California, Colorado, Florida, Georgia, Hawaii, Idaho, Iowa, Kansas, Maryland, Massachusetts, Minnesota, Mississippi, Montana, Nevada, New Jersey, New Mexico, North Dakota, Oklahoma, Oregon, Rhode Island, South Carolina, South Dakota, Texas, Utah, Vermont, Virginia, Washington, and Wyoming.
