That is a set of tracks. smile
There was a guy troweling the surface of a lump of concrete at a remote site. My dog walked over and plunked his front feet in about 8 inches of nice, wet concrete and watched the guy work the trowel. Dude looked over and made eye contact, said “ hi” to the dog, and went back to troweling. Took him about 30 seconds to figure out where doggie’s feet were.
