Query: Does what it should

I got a few laughs from the owners of the full-sized Chuckits, but it sends the ball flying nearly as far. If you have a larger sized dog, this is a good one because bigger dogs won't need to run as far as the smaller, faster dogs. I have a 1 year old German Shepherd and this works great for him. If you have a really weak throwing arm, then you may want to use the larger one, but I had no problem hurling the ball 200 feet or so.
