I see your point - it's a fuzzy line. IMO - all dogs are "emotional support" so, if you have a well trained well behaved dog - well, shouldn't it qualify?
I'm involved in a rescue for Australian Shepherds - I seriously like those buttheads. We recently took in a dog that was ...supposedly - an emotional support dog for an austistic child. It had a harness and a badge stating this. It was very hyper, untrained and not well socialized. The gist of it was the parents got it as a puppy from a "breeder" who said it would be a good "service dog". They registered it with some sort of internet agency - no formal training protocal or anything not to mention it was a PUPPY. Well they moved to CA, left the dog behind for a neighbor to care for and place. Nice dog, nice temperment - just needed training. But service dog? Give me a break. My own well behaved dogs (2 out of 4) would have been better qualified. Why can't I take them place eh?
I am not saying that you can't take them places.
I am saying that I, as a business owner, shouldn't be forced by the Government through the ADA be forced to allow pets in my place of business if I don't want them there.
I don't care if it's a restaurant, hotel, grocery store, or coffee shop. If I want to allow pets, I should be able to. If I don't want to allow pets, I should be able to ban them.
As I said, I understand dogs for the deaf, blind, seizure prone, even autistics. Those are not pets. They are working animals. They are trained for a specific function. But those pets that are used to make a person feel good?
I remember seeing an interview of a woman who had a miniature pony that she claimed was her support animal. She let it live in her house with her. Should a place of business be required to let a damned horse in because it made this woman feel good?
