If the other styles in this gallery lean serious, Rococo is the exception — and it's usually the first one people laugh at, delightedly, before choosing. Think François Boucher and Fragonard: powder blue and coral pink silk, ornate gold tassels, an ermine-trimmed drape, soft dreamy light with almost no hard edge anywhere in the frame. Your pet reclines on ornate silk cushions in three-quarter view, relaxed and a little smug, the whole composition asymmetric and intimate rather than formally centered. It's opulent on purpose — pastel rather than moody, decorative rather than austere — and it tends to suit pets with a soft or playful presence best: the lap cat, the small dog who's basically furniture royalty. Where Baroque says "coronation," Rococo says "salon" — a little frivolous, deliberately charming, unmistakably French. It's also, reliably, the style that gets the most reaction on social media, because nothing looks quite as funny-then-genuinely-beautiful as a golden retriever draped in ermine and pearls.
