The miniature horse is not included in the definition of service animal, which is limited to dogs. However, the new ADA regulations contain a specific provision which covers miniature horses.  Businesses must make reasonable modifications in policies, practices, or procedures to permit the use of a miniature horse by an individual with a disability if the miniature horse has been individually trained to do work or perform tasks for the benefit of the individual with a disability.  

Factors to assist in determining whether miniature horses can be accommodated are whether:

• the miniature horse is housebroken
• the miniature horse is under the owner’s control
• the facility can accommodate the miniature horse’s type, size, and weight
• the miniature horse’s presence will not compromise legitimate safety requirements necessary for the safe operation of the facility
