The dog is neighing

A small, white, fluffy dog with a round, groomed coat is suspended horizontally on a black railing, its front paws gripping the top rail and its hind legs dangling. The dog repeatedly opens its mouth wide in a yawn or bark, then closes it, while its head bobs slightly up and down in a rhythmic motion. The setting appears to be an indoor space with a large window in the background showing a building outside.
