An embodiment of the disclosed equine support boot comprises a base portion, at least one upper strap, and a v-shaped sling strap attached to a top section of the base portion, the sling strap being configured to pull the fetlock joint towards the attachment point to apply an upward force on the leg thus decreasing tensile stress in a localized area. In this embodiment, the disclosed equine support boot represents an improvement over known equine support boots because in known boots, sling straps rap horizontally around the horse's leg and thus do not provide an upward vertical force on the fetlock joint of the horse's leg. The use of a v-shaped sling strap in embodiments of the disclosed boot enables the straps themselves to apply an upward force toward the attachment point of the v-shaped strap when the boot is mounted on the horse's leg.
