Dogs adopting their new owners [View all]

Maybe two weeks ago, I saw a YouTube video about a shelter that would gather people who wanted to adopt a dog into a room where they would release one dog at a time, and let the dogs pick someone to adopt them. I'm a bit of a sucker for dog adoption videos anyway, and it was quite touching to see the emotional responses when a dog chose someone.

That was the first time I had seen a video like that, but curiously, since then I've seen at least a dozen. It seemed like such a sudden fad that I started to suspect that they might be AI, but if so, it's pretty convincing. Does anyone know if that's been a "thing" for a while, or is it as sudden as it seems to me?
