A service is simply a transaction where no actual physical products are transferred between the seller and the buyer. The seller typically agrees to perform a service and the buyer agrees to pay for the service. The buyer’s willingness to complete the transaction demonstrates the value of these services to society. Public services are usually those which society as a whole typically pays for anyway.

Under the law a service animal may be any pet that is allowed access to the premises of a covered entity. Covered entities normally include nursing homes, hospitals, nursing schools, and hospices. There are, however, other types of services which are not allowed access to the premises by animals. These types of service animals may be covered entities themselves or ancillary members of their staff.

When service animals must be allowed entry into the covered entity premises it is called a restricted entry facility. Service animals must be able to meet the requirements of the facility and they must also be physically capable of performing the expected tasks. Examples of the services which are often restricted are rabbits, ferrets, birds, and guinea pigs. A physically impaired animal will need to have a special carrier or wheelchair to allow them easy access into and out of the facility.

Another type of service animal is a confidential service animal. Confidential service animals are allowed to enter and stay on the premises but are not allowed to interact with other people. This means that if a dog is left unattended on the premises a handler may be unable to retrieve it if it becomes lost. The handler would likely need to surrender the dog to the facility for adoption if it became too difficult for him/her to take care of the dog.

Emotional support animals are usually allowed to enter homes and perform tasks which are necessary to the well-being of the person who has them. An example of an emotional support animal would be a dog who has been trained to provide companionship, such as a blind dog who can keep watch over its master at night or a dog who is trained to assist a person with mobility problems. This type of animal may also be called a service animal. Other types of emotional support animals are registered therapy animals, assistance animals, service dogs, and veterinary pets.

There are many reasons why a person would require the services of service animals. For example, a blind person may require assistance getting in and out of a car, or a sick person may need to be lifted into bed or to sit on a couch. In some cases a handler may be allergic to his/her own medicine. Also, service animals are often needed by those with mental disabilities who need help performing simple tasks such as picking up small objects, or helping a handler to move furniture. Finally, service animals are sometimes needed to protect the handler from potentially dangerous situations, such as with a blind person who needs to use a cane to retrieve something.
