The White Rubber Bone is an item no different from the other three Rubber Bones, besides color and being available in all versions. It is white with green "Nintendogs" text engraved on it.
DS & 3DS NTSC: "This toy is great for strengthening a puppy's jaw and helping it relieve stress."
3DS PAL: "This bone is good for stress relief and strengthening puppies' jaws."
Nintendogs + CatsEdit
In the Nintendogs + Cats versions, the "Nintendogs" engraving is absent and it does not make a "crystal" sound.
- Even though the White Rubber Bone claims to be made of rubber, when a dog grabs it, it sounds as though it is grabbing crystal.
- In addition to sounds, the bone makes a spring-like sound upon hitting something.
- The White Rubber Bone is the only bone available in every version of Nintendogs.
