The Rokan herding ball is the favorite toy of our Olde English Bulldog. It takes a beating and keeps on rolling. Their customer service is great.

Give the drive somewhere to go.
ROKAN is the interactive herding ball made for dogs with too much engine — Cane Corsos, Rottweilers, Pitbulls, and every breed with energy that has to go somewhere. The unpredictable roll and resistance mimics the chase-and-control instinct of herding, so your dog isn't just running, they're working.
Originally built for Cane Corsos. It holds up for any dog that hits hard and doesn't quit.
Durable, not indestructible: no ball is chew-proof against a determined power breed working it alone and unsupervised. ROKAN is built for interactive play, and holds up best when used that way.
