Pady Padme Fontanelle, the chocolate chihuahua, is a medical alert service dog in Albany, Georgia, who helps her mommy live with diabetes. She is friends with another service dog, the snow white German shephard Polar.
In the middle photo, Padme got to go to the public aquarium, and the dolphins were extremely curious about her. The bottom photo shows her in her winter outfit.
