The circus dogs of Prague

JR and his friends are on their way to Prague with his human, George, and George's Russian girlfriend, Nadya, where they plan to take in the sights and meet Nadya's brother, a circus performer. But something is amiss at the circus-- the animals are unhappy. Not only that, but a fancy new circus is coming to town, threatening to put everyone out of a job. It's up to JR and the embassy dogs to save the show, with the help of some unlikely accomplices.
