Pony training is a BDSM activity in which a dominant "trains" a submissive to be used as a pony in what is known as "pony play." This can involve making the submissive look like a pony through the use of hoods, bits, harnesses, saddles, bridles, and hoof boots. The pony may be made to perform for their master or to pull a cart. For some people, realistic sex toys, like a horse dildo, can be part of the fantasy as well.
