The Gnawt-a-Rock is a durable toy inspired by natural volcanic obsidian formed by rapidly cooling lava from Pacific Northwest volcanoes.

Made with natural latex rubber and a faceted surface with an irregular shape, this interactive toy keeps your dog engaged, whether chasing after its erratic bounce or nosing it around as an interactive slow feeder puzzle toy to stimulate their mind.
