You are not permitted to ask for papers if restaraunt or museum or park it's not allowed form of discrimination. If someone says they are the service dog they are permitted in. However, there are papers and documentation on all service dogs or confort dogs that have been through intense training for blind and some disabled. You may call the park and ask them if your permitted in with a service dog. They can not refuse.clearufication if service dog yes, if my family dog no.call them ask.
There is no official service dog documentation.
