Why not leave the dog at home if you know you’re going to a restaurant?
I’m not sure what you mean; it was a service dog.
I do not know the particulars of this vet’s need for a service dog, but I will hold up an example of a service dog for an person prone to epileptic episodes. The dog remains with them at all times to provide support. This comes in two broad forms.
One is a pre-episode response where the dog will warn the person and they can find a location where they can sit and not be at risk for falling and possible injury.
Second, is during an episode, the animal is trained to protect the person while during a epileptic episode. I have observed the particular animal guarding their owner.
Understand that since an seizure can strike at any moment, the presence of the dog to protect the individual needs to be maintained at all times. Even when they go to a restaurant.
Registered service animals, seeing eye dogs, etc., are permitted access to public spaces by federal law (Americans with Disabilities Act). Access by screaming psycho b****es (of the non-canine variety) can and should be revocable as soon as they open their mouth.
back to lurking school for you!
