Tricia Keppel's Italian greyhound Gonzo "hates going out in the cold," though "he's a pretty good sport about putting on his coat and boots." And to be fair, the dog does seem to be in pretty good spirits.
As inadvertently creepy as the opening seconds of this video are (one YouTube commenter compared Gonzo to Dobby, the house elf from Harry Potter, and they weren't far off), it's definitely a treat to watch Gonzo stomp around like a goon in his snow boots and hooded jacket.
Don't worry, little guy. The polar vortex is gone. You're safe now. At least until the next cold snap.
