For years I avoided buying one of these. What's wrong with using my arm instead of one of these dadgum fancy contraptions? I wondered. Well, this is TONS better. No more gross hands! You can just pick up the ball with this thing. Also, my throwing arm isn't actually that good, so now I can throw it clear across the field for my dog. Be sure to buy the correct size for your dog-- I have a standard Goldendoodle so he needs a large, not a medium.
