I bought this for my new grandpuppy as a shower gift. Her dad loved it and has already been playing fetch with her using the Chuckit. She is only 8 weeks old but already gets very excited when she sees someone getting it out of the closet. The ball that came with it is good for her age since it has a tennis ball type covering and she can easily grab it and bring it back. I also bought the smooth rubber balls which will work better for her when she is a little older.<a data-hook="product-link-linked" class="a-link-normal" href="/Chuckit-Ball-Launcher-Colors-Vary/dp/B00006IX59/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Chuckit!
