Foxhound

The Foxhound is a wolf-like hostile mob that spawns in the Nether. In Soulsand Valleys, they are blue instead of the usual red. Their attacks set their targets on fire.

Taming
To tame a Foxhound, the player must feed it enough coal. It is recommended to bring lots of coal, as sometimes they require many. Be aware that they will attack you whilst you try to tame them. Once tamed, they will have a collar like a wolf.

Use
Foxhounds have multiple uses after they have been tamed. First, they can be used as an "attack dog" like other tamable mobs. They are especially good at this as they light the targets on fire, making them great for hunting. The second use for Foxhounds is that they speed up furnaces if on top of it. Right clicking a tamed Foxhound will cause it to lay down and stay still.
