I have a Labrador mix with a Golden and he's a fetching machine...In québec we don't have much choice for rubber throwing discs except for the Kong and they are mostly discontinued. They are really heavy to throw and not tough enough (I need to by one every 2 month or so) When I found the Zisc we were so happy and it's so much better...you can throw it further without breaking your arm because it's really light, and it flies straight, Alfred (my dog) loves the texture, and it's really good on the snow because it floats...we love it (I even bought a hurley stick and that too is amazing) and the best part...it's eco-friendly
