Disclosed is an assembly or system and apparatus for applying pulsing electromagnetic field (PEMF) coils to the underside of an equine hoof. The PEMF coil is encased in an elastomer structure to form a “puck” that will protect the coils from moisture, dirt and damage from rough use. The coil, and preferably a puck containing the coil may suitably be placed on, in or under an elastomeric orthotic pad that is disposed in a suitable equine boot.
