FAQ

Quick answers about the KOREflex Ball.

  • The KOREflex Ball currently comes in one large size, about 4.75 inches, for the big-bite feel that strong, medium, and large dogs love. As a safety rule, a ball should always be too big for your dog to fit entirely in its mouth, since one that slips past the back teeth can become a choking hazard. At 4.75 inches it is too large to swallow for almost all dogs. If you have a very large, big-mouthed breed, just confirm it still cannot fit fully in the mouth. For small dogs, the 4.75-inch size is not recommended, but additional sizes are coming soon.
