Watch: Rescue dog becomes the rescuer

Watch as this tiny Pomeranian, named Chucky, appears distracted as it walks along the side of the pool and then tumbles in head-first.

The bull terrier, Jessie, notices the dog in distress and repeatedly tries to lift it out of the water by its scruff.

Jessie attends to the struggling Pom for 34 minutes, eventually managing to pull it out of the pool.
