Abstract: An equine safety sling for supporting a horse or other animal during transportation includes first and second outer straps, each outer strap having a front and rear end, thereby providing four ends; a front inner strap that connects the outer straps so that the device supports the animal behind the front legs of the animal; a rear inner strap that connects the outer straps so that the device supports the animal in front of the rear legs of the animal; and a main loop at each of the four ends of the outer straps, adapted so that the device can be retained utilizing the main loops so as to secure the animal in place. A sliding pin bracket may retain the sling to the inside of a trailer and allow the horse to be quickly released.
