It's a ritual that's as old as time. If dogs weren't such traditionalists, they'd probably be swiping right these days just like the rest of us. But no, they're sticking to their ancient habit of sniffing each other's butts. Why change the habit of a lifetime? We're all for dogs' natural behavior, which is why our Season's Greetings dog sweater features two pups doing exactly that. These cute little canines sit elegantly underneath a season's greetings slogan, surrounded by Christmas Fair Isle patterns. It's the amazeballs Christmas sweater your dog never knew he needed. Good luck with taking it off.
