Hi, I'd like to help you with your question.
Psychiatric Service Dogs are a relatively new concept. They have not been used frequently in the psychology field yet so information available is limited. But from what information is out there, it seems that any mental health disability that severely limits your day to day ability to function qualifies you for a service dog. Here is a link to a site that offers further information on psychiatrist service dogs:
They mention that they do not train or provide dogs for you so you would need to use your own pet and have them go through the training.
Your service dog can be trained to provide deep pressure stimulation. However, tactile stimulation is recommended for anxiety patients over deep pressure stimulation. Tactile stimulation is when the nerves under the skin are activated through touch. They are responsible for the sensations of texture, temperature and other senses.Tactile stimulation helps deal with the depersonalization symptoms of anxiety by distracting your senses from the panic feelings to a calmer, more focused and comforting sensation. The dog can also be taught to lean against their owner to help with the symptoms of dizziness and unsteadiness common with anxiety.
Contact the Psychiatric Service dog association for more information on how to train your dog to perform these services and what is offered in your state. You may also want to speak to your doctor about this type of assistance as you may need proof that you qualify for such a service.
