No flames here -
While I know some dogs are cleaner than a few humans I encountered while at the World - service dog or not - I wondered about the health inspector issues after I saw the dog in the woman's lap while she was eating at Main Street Bakery.
As a service dog user who has an invisible disability, I encourage all of you to be a little more open minded. Like I said before, there are many different kinds of disabilities to which service dogs help with and they come in all shapes, sizes, and breeds. I know at LEAST 10 people who use small breed dogs for their service dog. There are Bichons, Chihuahuas, Malti-poos, Min-Pins, Yorkies, the list goes on of dogs I know that are used as service dogs in one facet or another. I also know of a very specific Italian Greyhound who does his work by sitting on the lap of his handler. He needs to be close to her so he can effectively alert his handler to her condition. That's his job. So in a restaurant or not he needs to be close to her to do his job.
Now as service dog handlers, we all keep our dogs in very tip-top condition so it is quite possible that a service dog could be cleaner than a child. Children are allowed without any problems, right? I happen to have two children as well, but have high standards for them as well, but kids are usually harder to control than dogs are.
There are very clear circumstances where a service dog can be asked to leave and can even call the police to assist if needed. If the dog is unclean, barks more than once (once could be an alert), causes a disturbance, or anything of that nature. So if you feel that a dog is actually causing a disturbance, tell management. But don't talk nasty about it behind people's backs. Do something about it. Otherwise, ignore that there is a dog there and try to be polite.
It is not required by law for a service dog to be identified by a vest or anything else. As long as the dog is behaving appropriately there is nothing that a business can ask for as proof other than verbal assurance that the dog is a service dog, the dog helps with your disability, and they can ask what specific things the dog does for your disability, but they cannot ask what your disability is, for ID cards, or certification. So just because you do not see something on the dog does not mean the dog is a pet dog. It is possible that because of the heat there, the handler chose not to vest the dog that day.
Hope that helps you all.
