A service/assistance/emotional support dog is specifically trained and has the abilities to help individuals who have disabilities  that prevent or impede them from
carrying out daily tasks.

Desirable character traits in the service dog typically include good temperament or psychological make-up (including biddability and trainability) and good health.
Service dogs are often trained and bred by service dog organizations or by their owners. Labrador Retrievers, German Shepherds, and Golden Retrievers are the
most common breeds used as service dogs, however any breed or mix of breed is capable of being a service dog. When looking for a service dog candidate it is
very important to know as much as possible about the ancestry of the dog however it does not guarantee good health nor bad health or good or bad temperament
for the prospect, Service dogs are indeed very gifted canines some seem to be born with the innate ability to excel in the work they are asked to
perform.  Therapy dogs are usually not regarded as service dogs and by definition should not be considered as such. Therapy dogs do not give assistance or
support to their owners but do give comfort to the elderly and to those that are hospital bound.

Where Service Dogs are allowed
"Under the ADA, State and local governments, businesses, and nonprofit organizations that serve the public generally must allow service animals to accompany
people with disabilities in all areas of the facility where the public is normally allowed to go. Service dog handlers should take into account when deciding if a certain
environment/place is a safe place to bring their service dog, if it is unsafe for the dog to be present the owner should make alternate arrangements, possibly
bringing a friend or family member who cann assist them.

Service Dog Etiquette
The health and safety of the owner may depend on the dog's ability to focus and resist distraction. Many service dogs are trained to avoid distraction when wearing
working. Service Dog owners expect to be asked for permission before another individual interacts with the dog. It is advised not to pet a service dog unless having
asked the owner permission. Distracting a service dog is considered disruptive

Who can train a Service Dog

Disabled owners of service dogs are protected under the Americans with Disabilities Act of 1990, which generally gives those with disabilities  the right to be
accompanied by their service dog/animal anywhere the general public is allowed. Additional federal laws protect people with disabilities partnered with service
animals, as well as other types of assistance animals, from discrimination in housing (the Fair Housing Amendments Act[and on aircraft (the Air Carrier Access Act .
Actually, the Air Carrier Access Act does not define "service animal" and it is a misconception that the ACAA provides a broader definition of the term over the ADA.
Under the ADA, businesses are permitted to deny access to service dogs that are not behaving properly. They may also be excluded if the presence of the animal
constitutes a fundamental alteration of the business or poses a direct threat. Persons with service dogs are not required to pay any additional fees on account of
the service dog, though the owner is responsible for any damages caused by the dog.

Service dogs should wear special vests and /or have ID tags, but they are not a requirement of the ADA. The ADA does not require that the dogs wear vests or
have ID tags but it makes it easier for the owner to have full access without incidence.
Public access rights of owners of service dogs vary according to country and region.
