PHOENIX -- Arizona Gov. Jan Brewer has signed into law legislation that adds miniature horses to the state's definition of a service animal.
The bill Brewer signed Friday allows individuals with disabilities to enter businesses with trained service dogs or miniature horses.
The federal Americans with Disabilities Act regulates service animal requirements in public places in Arizona. The federal law already recognizes miniature horses.
The new Arizona law does not recognize other species of service animals. Supporters say the law ensures people don't go into public places with rats, snakes or other trained animals.
Miniature horses range in height from 24 inches to 34 inches measured to the shoulders. They generally weigh between 70 and 100 pounds.
The service animal bill is HB2401
