I bought this for the dog at the Country Club where I worked so we could play in the morning before work. He's a "goose chaser" dog. Yes, they spent 22k dollars on a dog to chase geese when my dog would have done it for free, but whatever. Should have rescued a dog. Little did I know that this would reignite Jock's lovely little quirk where he likes to steal golf balls after people have hit them and then they wonder why they can't find him and there goes a 22k dollar border collie running far, far away from them and they never see their ball again. Sorry, not sorry. I bought a glow in the dark ball to go with this because it's still dark in the AM and Jock can see it. But, we had to stop playing because he relapsed and started stealing a plethora of balls again. I don't regret it.
