Cairn Terrier Coffee Co 12X12 Modern Vintage by LegacyHouseArt Cute sign for any cucina, however the Cairn Terrier does not need any caffeine with their natural energy and spunk. Ha, ha. Long live the Cairn Terrier, a small dog with a big personality. I can relate to them for sure! Love my two Cairns, Maggie and Thurman.
