Bone

Bones are items primarily obtained as drops from skeletons.

Mobs
Skeletons, wither skeletons, and skeleton horses may drop 0–2 bones upon death.

Fishing
Bones can also be obtained by fishing as part of the junk category. The best chance of catching a bone is achieved without the Lure or Luck of the Sea enchantments, yielding a 1.2% chance.

Usage
Using a bone on a wild wolf has a $1/3$ chance of taming it. Bones cannot tame an angry wolf or a wolf that someone else has already tamed.

Trivia

 * As with sticks and blaze rods, bones are wielded as a tool instead of an item.
