While websites such as United States Service Dog Registry Service Dog Registration of America offer free service dog registry, a certificate is not a requirement under Federal law and therefore ordering a certificate is an elective and paid service provided by a private company. There is no universally recognized service dog certificate or certification as of 2015. As per the Americans with Disabilities Act, a service animal owner has the right to be taken at his word without providing documentation.
As it is unlawful to demand proof of an animal’s licensing, training or certification to work as a service dog, there is a provision to ask two questions of the person accompanied by the service animal: whether the animal is required due to a disability and what task the animal performs. A public entity does not have the right to ask about the specific nature of the disability of a person with a service dog.
A large number of companies employ service dog certification schemes, and charge a varying fee amount to provide a certificate for the animal. Some such companies include the Service Animal Registry of America, Service Dog Certification of America, American Service Dogs and the United Service Animal Registry.
