What device uses a leather strap to restrict the movement of a leg?

A hobble is specifically designed to restrict the movement of a horse's leg by using a leather or synthetic strap. This device is often used to prevent a horse from kicking or to limit its mobility while still allowing it to move at a walking pace. Hobbles are typically applied to the lower leg and fastened around the pasterns, thereby creating a constraint without causing excessive pain or injury.

In contrast, a cross tie is used to secure a horse's head and keep it stationary, while a nose lead is a device used to guide or lead a horse through its nose. A lip twitch, on the other hand, is applied to the upper lip to distract or calm the horse during procedures like veterinary exams or treatments. Each of these tools serves a different purpose, but the hobble is distinct in its specific function of restricting leg movement.
