Knockoffs and Forgeries
It's illegal to take most dogs on public transportation or in taxis. The one exception to this is helper dogs. If you're blind or otherwise need a dog to help you around town, you can take it anywhere you want. You can identify worker dogs by their orange jackets emblazoned with 'Helper Dog' embroidered across the side. So of course a cottage industry of people making and selling fake helper dog jackets has popped up. Yesterday I saw a Chihuahua straining at the end of its leash wearing a helper jacket, and the owner didn't even bother wearing sunglasses to pretend to be blind. Not that it'd matter -- no one in their right mind would believe this dog was offering humanity any kind of help. The guy would have been better off just putting the dog in his pocket to take it on the train or in taxis than getting it a fake helper jacket.
