Your four-legged friend is sure to love this Ballyhoo ball thrower. Fun is guaranteed, whether you use it indoors or outdoors. The machine can be operated completely independently by your dog, who must simply drop a small tennis ball into the upper opening of the machine. You may need to show your dog how to do this at first. Very soon, your clever pet will have understood the principle and will deliver the balls back to the machine independently. The ball thrower automatically ejects the ball from the opening to a set throwing distance. Your dog can then chase after it, catch it, bring it back and start again. The game can last as long as your dog wants. The machine can be operated via a mains plug or with batteries. Mains operation is particularly suitable for use inside the house. Don't forget to take the machine to the park where you be able to set a longer throwing distance, which may be unsuitable for your home. The device has three distance levels. Please note, that balls of 4cm in diameter may be swallowed by large dogs.
