Personal Information: Client's Name. To qualify for an emotional support animal in California, you need an ESA letter from a California-licensed mental health professional.Three templates for service dog letters from healthcare professionals, covering the types of letters service dog users may legally need. We may ask you (1) whether the dog is a service dog required because of a disability, and (2) what work or task the dog has been trained to perform. Service dogs are a great way to help someone struggling with PTSD. Service dogs can negate some of the worst side effects of PTSD. The issued ESA letter must include their license number, the effective date, their jurisdiction, and the type of professional license. If you have an ESA, you will need to request a reasonable accommodation in order to keep the ESA with you. Looking to qualify for a California PSD letter in California, Utah, Oregon, or Indiana?
