The Lotus Ball is the original treat-dispensing pull-apart toy! This stimulating, reward-based toy will keep your dog in the game when you are training. The three parts of the ball or "petals" are lined with Velcro so that the dog can open the ball and get to the treats inside without destroying the toy. Lotus Balls are an excellent toy for food-motivated dogs so that you can throw their reward during your agility training, and dog trainers around the country have come up with innovative ideas for using Lotus Balls to teach contacts, distance skills, and much more! These are the only real Lotus Balls available. So accept no substitutes! The Mini Lotus Ball is 2.5" in diameter and is made from a softer nylon than the Small and Medium Lotus Balls. Note: The Lotus Ball is a dog training tool, and is not intended to be given to the dog for self-play. Your dog should be supervised whenever you are using the toy with treats inside.
