A letter from your doctor does NOT make your dog a service dog or grant you permission to have your dog with you in all place. A letter from your doctor makes your dog an ESA. ESAs are allowed in no pet housing and on airplanes.

Now....How do you get a PSD?

To have a PSD, 3 things MUST be true:

1) You must have a life limiting disability.
2) Your dog MUST be task trained to do something to mitigate your disability. **has great resource on how to start and a list of tasks.
3) Your dog MUST be trained to behave in public.

As to training...

ANYONE can train your dog. You can train your dog if you know what you are doing. In the US, service dogs are not certified or registered, so there is really no such thing as a certified service dog. You can buy "certification" on line for several hundred dollars, but its not worth the paper its written on and does not make your dog a service dog.

I invite you to come over to ** There are many PSD handlers who can support you and help you do this LEGALLY!
