This coloring page depicts a small and friendly dog who is eagerly awaiting entry into a large, mysterious door. It has its paw outstretched, as if begging to be let in, and its head is tilted upwards curiously. To color this image, use warm colors for the door such as rust, yellow, or orange. Use grey for the dog's fur and a pinkish-red for its nose and ears. Add some subtle detailing like white or yellow highlights on the dog's fur to create a realistic look. Finally, use blue or green around the doorway and door handle to create a contrast with the warmer colors.
