Here's an article about a celebrity with a fake service dog. It seems the only reason his dog is wearing a service dog vest is so the dog can fly in the cabin of the plane with him. I wish airlines would crack down on this kind of thing.
See the photos of him carrying the dog through the airport? That is a dead giveaway that it's not even a real service dog. A real service dog would be walking through the airport, heeling nicely.
What's wrong with people pretending their dogs are service dogs when they're not? Well, besides the fact that it's dishonest, unethical, and illegal, it ends up making things harder for people with real service dogs. The public gets used to seeing all these fake service dogs and suspects that real service dogs are also pretend service dogs. They get tired of dealing with ill-behaved pets and just want dogs to stay out of public places altogether. I wish airlines and other businesses would start excising their rights and not allowing people to bring in fake service dogs.
