This is a guide dog carrying armrests. It and the service dog are both a kind of working dog. It should be noted it was added to emoji in 2019, and most platforms and operating systems may not yet support its display.
Guide dogs🦮 are allowed to go where other animals are not, boarding airplanes, for example, and trains.
If your dog is right-pawed and the swirl goes anti-clockwise, then your dog is more likely to be calm, confident and self-assured exactly the traits that a guide dog🦮 needs.
