When it comes to the mental or emotional issues, there are 2 different animals out there called as ESA (Emotional Support Animal) and PSD (Psychiatric Service Dog). This is because these 2 dogs will do 2 different things, so based on that it is classified. But, you doctor only decide whether you need to ESA or PSD. At the same time, you can able to use anyone of these dogs, if your state allowed those dogs in the public places. Therefore, at first, you need to check for this factor from local and state laws. However, there is no need of any special training to keep on the outside.
Your disability should be provable through your doctor if you want to use a service god. In addition to that, you also need to get proof for your ESA or PSD dog is properly trained. If you have proof for these factors, then you can carry the ESA or PSD dog along with you anywhere. In order to take a dog to you, you no need to keep a piece of paper to prove you’re disabled mentally. Your mental professional only can say whether you’re qualified to get a service dog letter or not. But, your dog also should qualify for the treatment.
