While Team Avatar was staying in Ba Sing Se, AvatarAang toured a rundown menagerie. Seeing the animals' poor conditions, the young Avatar reconstructed the zoo outside the city walls, though when he used the bison whistle to call for the zoo animals, many domesticated creatures, among them a dog, responded to the call and ended up in an elephant mandrill's pen.
The canine that was present at the oasis had black fur with a brown underbelly. It had a light brown muzzle and white paws, and the end of its tail was a beige color.
Another breed of dog in Ba Sing Se was brown-furred. It had tiny paws and long floppy ears that fell down the sides of its head. Its face contained light brown features and golden-colored, droopy eyes.
The dog which inhabited the Misty Palms Oasis is similar to a Bernese Mountain dog, though it is thinner and has less hair. It also bears a resemblance to the Appenzeller Sennenhund.
