The Red Rubber Bone is an item no different from the other three Rubber Bones, besides color. It is red with white "Nintendogs" text engraved on it.
"This toy is great for strengthening a puppy's jaw and helping it relieve stress."
- Even though the Red 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.
