Psychiatric: A Medical Alert Assistance Dog specially trained to enable individuals with psychiatric disabilities to lead more independent lives by performing tasks that the person otherwise could not do or would have extreme difficulty doing for him/herself. Handlers for these dogs are generally under medical care or have been diagnosed with a psychological condition with the most common diagnosis being: Post-Traumatic Stress Disorder (PTSD), Traumatic Brain Injury (TBI) or various personality disorders. These dogs are trained to perform tasks such as search specific rooms before their handler enters, interrupt nightmares, alert their handler to someone approaching from behind, detect changes in their handler’s cortisol levels and physically interrupt disruptive episodes.
