One way to find a missing puppy is to print up fliers with a picture of the dog and post them around the neighborhood. Calling local veterinarians, pet stores, animal shelters and rescue organizations also sometimes helps locate a lost dog.
Post the fliers where passers-by are likely to see them, such as telephone poles, park entrances and grocery stores, and offer a monetary reward for the return of the pet. Gather family and friends and search the area where the dog was last seen. Dogs often run away to a place that's familiar, so look for the puppy near the parks, pet stores and other places it has been before. Make sure to look under parked cars and bushes; it might be frightened and hiding out of sight.
