Query: pure Labrador joy

These smaller, softer discs are even better than the full-size for playing with a dog. We play right after dark. Our yellow Lab has the Night Dawg collar and she has the MOST fun, while we love the light show. We have hit them into trees, our fence, and one even went briefly into our brook and they haven't lost their colours. And these Junior size have a much smarter battery system. We lost the battery on one of the full-size, which is why we switched to these and I'm glad we did because these are even better than the wonderful original. Really a brilliant toy and sooooo much fun for frisbee after dark.
