Our Puppy Paws Harmony Balls and Paws on My Heart Angel Callers celebrate our pups, young and old. They love us unconditionally, and we love them with our hearts. Show your love by wearing one of these necklaces; each has a soft, gentle chime in the orb you can hear when shaken near your ear. Choose from silver or gold, black, white, or all metal. Our enamel ones have the option of an angel wing.
