There haven't been any pet dogs in North Korea in decades. They were all eaten several famines ago, except for a tiny number that belong to the ruling class.

The book The Aquariums of Pyongyang (2000) talks about a man who escaped from an NK work camp to rural China. At one point, he's hiding and watching a farmhouse. He sees a plate of meat on the ground and thinks, "Someone forgot about this." Then an animal approaches the meat and he thinks, "Oh, no, the animal will steal the food!"

Then the animal eats the meat, and the farmer comes out and touches the animal in a friendly way, and the narrator was completely confused - because he simply had never even heard of the idea of a pet.

And that was 20 years ago and this guy was actually one of the privileged classes.
