Rumble Ball

Rumble Ball is the perfect size for medium to large dogs and is forged in Erie, PA from premium American-made natural rubber.

For dogs who shred everything else, its solid-core, industrial-strength rubber is tear-, puncture-, and chew-resistant—yet soft and flexible for safe, satisfying chewing.

Safety and quality are built in: food-safe, toxin-free natural rubber compounded in the USA; third-party tested and CPSIA approved; designed to prevent sharp edges and splintering; and dishwasher safe for easy cleaning.

A portion of every purchase goes to Project K9 Hero — "Protect Those Who Protect Us." This commitment, plus durability you can feel, helps set Rumble Ball apart.

Max durability for aggressive chewers: over 500,000 sold. Trusted by K9s: Monster K9 toys are a go-to choice among police and military K9s worldwide.

Lifetime Quality Guarantee: built to last and backed for life. If your toy doesn’t hold up or meet your expectations for toughness, we’ll give you a refund or one-time replacement—no BS and no fine print.
