ADA & State Service Dog Laws

This page provides general information. Always consult official sources.

ADA Overview

The ADA requires that service animals be under the handler’s control at all times, typically using a harness, leash, or tether, unless using these devices would interfere with the animal’s work or the person’s disability. Service animals must be housebroken, and the handler is responsible for their care and supervision.

• Businesses may ask only two questions about a service animal.
  • Is the animal a service animal required because of a disability?
  • What work or task has the animal been trained to perform? 
• No documentation or vest is required under federal law.
• Service animals must be under control and housebroken.
