Rumble Ball Rubber Dog Toy for Aggressive Chewers | Monster K9

The Rumble Ball is a heavier-duty fetch and chew ball built for dogs who need more — more weight, more texture, more durability. Made from solid-core natural rubber in Erie, PA, it's the same K9-trusted construction as Monster K9's full lineup, with a satisfying rumble feel that keeps dogs engaged longer.

Why Dogs (and Their Owners) Love It

• Heavier, more substantial feel — at 12 oz, it's built for powerful retrievers and large breed chewers who want real resistance
• Textured surface — promotes engagement during fetch and solo chew sessions
• Tear, puncture, and chew resistant — solid-core industrial-strength rubber that outlasts standard fetch balls
• Trusted by working K9s — over 500,000 Monster K9 toys sold; go-to for police and military K9 handlers worldwide
• Dishwasher safe — rinse off the yard and toss it in the dishwasher
• Gives back — a portion of every purchase supports Project K9 Hero: "Protect Those Who Protect Us"
