Space Dog

The Space Dog is, as his name states, a massive legendary dog that lives in space. He enjoys biting the Moon, as Ma Ma says.

Personality
The Space Dog acts just like a dog, being playful and likes biting on things.

Appearance
The Space Dog is a dog of the chow chow dog breed, with orange fur and a blue tongue. He is said to be as large as the moon itself, but when he does appear in the end, it is shown the dog is only large enough to gnaw on a satellite.

History
It is unknown how he came to life or if there are any more space dogs.

As Ma Ma says, the Space Dog likes biting the moon sometimes, and that's how the moon phases exist.

When the moon is full, it is because Chang'e makes him spit it out.

He appears at the end of the movie biting a satellite when Chang'e's lions take Fei Fei, Chin and Croak home.

Trivia
