This is not a chew toy. Developed and field tested by law enforcement K-9 handlers this "Moki" rope tug dog ball toy by K9 Ops is a solid, multi-layered, slow-cured natural rubber dog ball paired with 16" Para-Max extra strength paracord rope. It is a very high-quality rope, but because your dog wont be able to destroy the ball they will chew the rope if you let them. And I am sure we can all agree that no rope is indestructible. We do not honor replacements if you allow your dog to chew the rope or knot ends. Don't be "that guy", you're better than that. The signature hex-shaped design ball and raised logo placement helps enhance the grip for throwing. It has high impact bounce for hours of play and is compatible with popular dog ball launcher.
