People training quadripeds to walk on hind legs (You Tube question)

Lately, I’ve seen some You Tube videos of people, who mostly appear to be from China, who film their pets with clothing and walking on two legs. Most of them are monkeys, but there are videos of dogs and cats doing the same thing.

Does anyone know why they do this? Among other things, it’s not natural to the animal, especially if they are expected to ALWAYS walk in this manner.

Fashion of the day. People do stoooopid things in the name of looking cool. Makes me sick.
