A psychiatric service dog is a specific type of service dog trained to assist their handler with a psychiatric disability, such as post-traumatic stress disorder or schizophrenia. Although assistance dogs have traditionally helped people with disabilities such as blindness or more recently deafness or mobility disabilities, there is a wide range of other disabilities that an assistance dog may be able to help with as well, including psychiatric disabilities
Like all assistance dogs, a psychiatric service dog is individually trained to do work or perform tasks that mitigate their handler’s disability. Training to mitigate a psychiatric disability may include providing environmental assessment (in such cases as paranoia or hallucinations), signaling behaviors (such as interrupting repetitive or injurious behaviors), reminding the handler to take medication, retrieving objects, guiding the handler from stressful situations, or acting as a brace if the handler becomes dizzy.
Psychiatric service dogs may be of any breed or size suitable for public work. Many psychiatric service dogs are trained by the person who will become the handler—usually with the help of a professional trainer. Others are trained by assistance or service dog programs. Assistance dog organizations are increasingly recognizing the need for dogs to help individuals with psychiatric disabilities, and there are even organizations dedicated specifically to supporting psychiatric service dog handlers. Service dogs, including psychiatric service dogs, are allowed to accompany their handler in any location that is normally accessible to the public whether or not health codes or business policy normally would allow a dog to enter, provided the dog behaves properly and does not interfere with normal operations (e.g. barking, biting, defecating, or obstructing other people) or pose a direct threat to the safety of others.
