The Blithedale Animal Shelter has just ended its annual holiday sale for dogs, and miraculously all but a few have been adopted. An unexpected, welcome surprise for the shelter staff, and great news for the lucky pups who found homes. But for the dogs that remain—a high-strung Lab puppy, a three-legged Chihuahua, a Golden Retriever, a hard-luck Pit Bull Terrier; and a smart, old dog—it will be a lonely and cold Christmas Eve.
