Dogs are mammals that live on Planet Earth, Mobius and the Special Zone. Many breeds of dog are shown to be extremely loyal companions, living in harmony with humans. Domestic dogs are often characterised by their habits of chasing their own tails, sniffing other dogs' bottoms and their varying skills of being guard dogs. There are also wild dogs that are much less friendly.
