Is Twix a Dog or a Chair?

Ryan and Twix had to keep an eye on Paul while he was outside this evening. They sat at the door like this for at least 5 minutes. It was enough time for me to notice it, get the camera, take pictures and then stand and laugh at the two of them for a while. Twix is so tolerant of these boys. She lets them crawl all over her. Here's Ryan really leaning in to get a good look at Paul. It looks like Twix is doing the same.
