"I have a labrador and I bring this everytime we go to the dog park. He'll run for hours and hours without me ever having to break my arm trying to throw it far enough (i'm a girl and throw like one too!). I forgot to bring the ball chuckit once and realized how much I depend on it! Honensly I couldn't live without this thing!! My dog will actually try to put the ball in it himself if I am not fast enough."
