Horse tack - online puzzles

Tack is a piece of equipment or accessory equipped on horses in the course of their use as domesticated animals. Saddles, stirrups, bridles, halters, reins, bits, harnesses, martingales, and breastplates are all forms of horse tack. Equipping a horse is often referred to as tacking up. A room to store such equipment, usually near or in a stable, is a tack room.
