Dog

Dogs are a planned passive mob. They will serve as pets to the player.

Notch also said in a twitter post that Wolves can be tamed to produce pet dogs. It is believed that they will be used to hunt, example to send them out for a day or two to find food. Dogs are to be rare and not a common sighting. Notch has confirmed the addition of these animals upon having breakfast with a friend, along with confirming Wolves, as said on his blog. Dogs will help you track down the nearest Workbench, which is assumed to be your base. Dogs will also confuse enemies, which may be a good way to attack Skeletons and Creepers.
