The small and handy Firedog Dummy Ball - not just for training with puppies, but great for young and adult dogs, too.
 
Comes with a long throw rope, a traditional toggle and also a round plastic handle, making it a really versatile piece of kit. Its compact design means it doesn't take up much room in game bags or vests.
