The Reaction Ball Dog Toy by Dexas us is a durable, innovative fetching toy for long-lasting play. The contoured, textured design makes it easy for dogs to grip and retrieve during a game of fetch. The Reaction Ball's grooved and raised nibs make it easy for dogs to pick up, carry and run. The design also encourages an unpredictable bouncing action, causing the ball to bounce randomly, engaging your dog's natural prey and chase instincts. The Reaction Ball Toy features a hollow chamber to store and hide treats and kibble and encourage play. The Dexas Reaction Ball Dog Toy is part of the Dexas Off- Leash Dog Toy Collection. The Off-Leash collection offers uniquely designed leash-attaching toys that allow pet parents to take along their pooch's favorite toy without having their hands full. Each Dexas Off Leash Toy attaches to a leash with a carabiner that features an innovative key that can connect or disconnect the toy for play or hands free toting during a stroll. Simply connect the carabiner to the leash, insert the carabiner key into the toy, twist and you're ready to go. Reverse the process to disconnect the toy for play and fetch time with your pup. Dexas Off-Leash toys are made of durable BPA free TPE and float for water play. Off-Leash toys feature a gentle scent that is appealing to pups and people alike. Proudly designed and made by Dexas, the manufacturer of popular collapsible pet feeders, travel cups and the best-selling dog paw washer, the MudBuster.
