This lighthearted addition to books about art for children combines art appreciation with a twist. Once a year when the museum is empty, dogs in the paintings have their special night out. They romp around the museum and, just at midnight, jump back into their frames. This year, partygoers had food and fizzy drinks in the gallery and the dogs enjoyed the leftovers. When the revelry was over, four dogs jumped into the wrong pictures. A young girl points out the mistake and everyone is astounded. People line up all year to see the unexplainable. A year passes until the next dog's night out when, dissatisfied with their new surroundings, the dogs move back to their right places. Hooper's (The Drop in My Drink, 1998, etc.) text is fast and funny, filled with descriptive phrases matched well by the illustrations. Curless, a London political cartoonist, did the initial drawings, but died before he could complete the illustrations; Burgess finished the work in his style. All the dogs pictured are reproduced from paintings in the collection of the National Gallery in London. A picture index of the featured paintings is a useful addition. Text and illustrations combine to make an amusing read and one that will compliment other more serious works about art for children. (Picture book. 5-8)
