Fire Hydrants

How To Craft A Fire Hydrant
There are three colors of fire hydrants, Red, Yellow and Blue.

What Fire Hydrants Do
Fire Hydrants are essentially your way of spawning wild dogs without a mob spawner. If you craft a fire hydrant and place it anywhere in your world, dogs will being to spawn. They spawn in groups of 1-3 but very rarely are there more than one, which makes it difficult to breed a dog of the same species. Any breed of dog can spawn and they do not need anything other than a light level of 3 or higher, so placing it in daylight will work just fine.
