Mashable reported the dog’s name is Hank and is a support animal for an interior designer who founded Ace of Hearts Dog Rescue. Due to an illness, the dog can only move with the aid of the cart in the picture.

The dog and his owner sat in the first row of first class and reports say he spent most of the flight lying on the ground and didn’t make a noise during the flight.
