Dublin absolutely LOVES this ball! It occupies him all evening. He chews and chews and hasn't made a dent in it — and he loves when I throw it because it bounces sooo high!

Project Play It Forward
10,000 shelter dogs. One bouncing ball at a time.
Shelter life is loud, stressful, and bleak — and for many dogs, a toy is the single thing that can flip the switch from "ignored" to "adopted." A WUNDERball in a kennel keeps a dog alert, engaged, and showing their real personality to adopters.

The 30-Day Tail Waggin' Guarantee
If your dog isn't happier on this leash, we'll make it right.
We've been making dog gear since 2004 — nine leash prototypes, one patent, and a whole lot of Pennsylvania winters. Every leash, coupler, and treat in our lineup is tested by our own pack before it gets anywhere near yours. We're so sure your dog will love it that we back every order with a 30-day money-back guarantee.
If tails aren't wagging within 30 days, just reach out — we'll replace it, refund it, or send a different size. Your dog's happiness is the whole point.
Questions training households ask us
If you don't see your question here, just email shop@gowacky.us — we read every one.
What size WUNDERball should I get for a puppy that's still growing?
Pick the size for the dog's projected adult weight. Puppies grow into the WUNDERball, and the larger ball encourages full-mouth play that's safer than tiny balls a puppy could swallow. If you're between sizes, size up.
Why pair the ball with treats?
The WUNDERball is the chase-and-return tool. The treats are the mid-fetch reward. Together, they're a training loop — and training becomes a game your dog actually wants to play. Most owners use the treats during the first week to teach "return" behavior.
Can I mix flavors, or do both bags have to be the same?
Totally up to you. Toggle 'Mix the flavors' on the picker above to grab one bag of each — most multi-dog households prefer this. Single-dog owners often pick both of one flavor based on what their dog already likes.
What if my dog destroys the ball?
Our 30-Day Tail Waggin' Guarantee covers the whole pack. Within 30 days, if anything's destroyed or your dog isn't loving it, reach out and we'll make it right.
How long does the WUNDERball typically last?
Most owners report 5+ years on a single ball. Many customers tell us they've owned the same ball for 8-10 years. Made in North America from solid natural rubber.
How does the bundle discount work?
The 15% off applies automatically when you add the Play & Train Pack to your cart. No code needed. Free shipping kicks in once your pack clears $49 (every combo above the smallest qualifies).
