Here’s a cheery middle-of-the-night link. Lily the dog runs ridiculously fast, like rex-run fast. I’m amazed by her dexterity. I’m going to go ahead and write the stupidest review of this video: “makes me wish I were a tiny tiny man so I could ride Lily like a horse. also makes me wish I had a horse.”
As with most videos on the internet, you can skip the first minute, which fits the Wadsworth Constant.
