Disability rights for users of assistance animals, Mass. Office on Disability.
Provides an outline of the definitions, laws, rights, responsibilities and "relevant processes for service animals and emotional support animals" in places of public accommodation, housing, transport and employment. Persons with disabilities have the right to be accompanied by a service animal wherever the person is allowed to go. Must be under the handler’s control at all times. In most cases this involves use of a harness or leash.  In housing, persons with disabilities have a right to reasonable accommodations, including the right to keep an assistance animal.

Only dogs and miniature horses can be service animals. If the animal is not a dog or miniature horse, it can only be an emotional support animal or pet.

There are two standard questions that someone can ask a dog owner:

  1. Is the dog a service animal required because of a disability?
  2. What work or task has the dog been trained to perform?

The law requires staff to take the individual at their word.

For more information on the types of questions a person can and cannot ask, see the section titled "Identifying the type of animal".

Certification and registration

"Assistance animal owners in Massachusetts are not required to possess any certification or identification." However, "[a]ll dogs, whether pets or assistance animals, need to be registered with their town/city, but there is no official registry of assistance animals."
