ADA is the BIG GUNS when it comes down to Americans with Disabilities Act, When it comes to service dogs they do not play well with any business or person telling you can not bring your service dog in....Tell your landlord that you are turning them in to ADA, you may have to tell them what it is.
Here in New Mexico it's wide open on having service dog. Here you can train your own dog....NM also uses the Americans with Disabilities Act as the Law.....Some states are somewhat different, but can not undo Fed law.
If it were me, I would not do a damn thing on Sat. other than tell them your are going to turn them in to the ADA!!! If they don't know about the ADA and service dogs, they will shit there pants when they find out. If you have a letter for the dog from your Doctor, it's an Rx.
A restraunt here in town would not let a Nam vet in with his dog. He just call the police, not only did he and the dog go in the restraunt, but the cop wrote them a ticket. Owner of restraunt told the cop that the dog was not coming in. Wrong thing to say.......
Call ADA they should have an office in your state or your state my enforce the ADA law. "They're charging me for the dog." Tell that to the ADA or you state.
