The Ruffwear Gnawt-A-Rock Rubber Dog Throw & Puzzle Toy is modeled to look like a stylized piece of Obsidian from a lava flow! This durable throw toy is inspired by natural volcanic glass formed by rapidly cooling lava from Pacific Northwest volcanoes. Unlike Obsidian, the Gnawt-a-Rock is made with natural latex rubber, with a faceted, gum-massaging surface. Its irregular shape creates an erratic bounce, and it has a treat-dispensing design for interactive play and reward.

Part of the "Pacific Gnaw-west" toy collection, which is inspired by Ruffwear’s home of Bend, Oregon, and its natural surroundings.

  • Internal chamber dispenses up to two cups of kibble or small training treats.
