He wrote on September 30, "Our ZE:A'S (fan club name) sent a picture with the sky; only then did I see a pretty sky.  Thank you.  This is a foreign dog named Puzzle, who was mischievous during our photo shoot in the Rocky Mountains, but also intelligent and only understands English.  I want to keep him.  Let's resist."

In the picture, he appears to be wearing a padded jumper next to the dog, Puzzle.  Both of them are looking into the camera with their sweet puppy eyes.  

It is not a surprise he wants to keep the dog as they already look so similar and Puzzle is just plain adorable!
