The term 'dog restraint' can refer to two different items: a LEASH and a chokechain. A LEASH is a long cord or strap that attaches to a dog's collar and is held by the owner, allowing them to control the dog's movements. A chokechain is a metal chain with two loops that fits around a dog's neck and tightens when pulled, allowing the owner to control the dog's behavior. Both of these items are used to restrain dogs and keep them under control.
