A ball can change a shelter dog's life.
For every WUNDERball you donate, we match it ball-for-ball — straight to shelter dogs across America. Our goal: 10,000 dogs with WUNDERballs, one wagging tail at a time.
If you have ever walked a shelter aisle, you know the feeling.
The long-term residents leaning against the chain-link. The quiet ones tucked at the back of the kennel. The high-energy pups with all that love and nowhere to put it. A shelter is a stressful, bleak place — and it hides the warm, loving dog underneath.
A WUNDERball gives that dog a voice. A dog with something to play for stops pacing, stops barking, and starts showing an adopter exactly who they really are.

The pack's progress.
Every WUNDERball donated moves this number. Updates the moment your donation clears.

Most shelter dogs have never held a real toy. We’re changing that, one WUNDERball at a time.

WACKYwalk’r started in 2004 with one obsession — making life genuinely better for dogs and the people who love them. The WUNDERleash came first; the WUNDERball followed in 2019 and became our all-time best seller. Built from the same dense, vet-recommended natural rubber as our leashes, the WUNDERball is ultra-tough, top-rack dishwasher safe, and engineered for the kind of relentless play that wears most dog toys down to nothing in a week.
Most shelter dogs never get a real toy. Tennis balls shred in minutes. Hard plastic toys hurt teeth. Plush toys get destroyed and trap bacteria. So the dogs go without — and the data is unkind. Research from the University of Lincoln and ASPCA-cited studies show that shelter dogs seen playing with a toy are adopted up to 70% faster. A bored, kennel-stressed dog stays in the shelter longer. A playing, engaged, alert dog gets noticed — and adopted.

That research is the whole reason Project Play It Forward exists. We match every WUNDERball you donate 1-for-1 — you give one, we send two — and ship them directly to shelter partners across America. No middleman, no retail markup, no warehouse holding. From our hands, straight to a kennel.
Why 10,000? It’s the number of shelter dogs across America who’d be alert, engaged, and showing their best selves to adopters every single day if every shelter had a WUNDERball in every kennel. 10,000 isn’t a vanity number — it’s the number that meaningfully changes adoption outcomes in the regions our shelter partners serve. We’re not stopping when we hit it; we’re celebrating, then setting the next one.
"Ask anyone here what the best day looks like. It's not a sales number. It's a shelter photo: WUNDERball in mouth, tail waggin' like crazy, 'ADOPTED' written across the kennel card."
Michael Young - Founder, WACKYwalk'r

What it can cost a shelter to house one dog. A WUNDERball helps that dog get adopted sooner — saving the shelter money and freeing a kennel for the next one.
A donation is $12.99 — about the cost of one takeout order. Skip it once this week, and two shelter dogs get the toy that helps them get noticed.
Every mission, every dog.
Each WUNDERball lands in a real shelter. Each mission ends with a story.

Why a ball actually matters.
Researchers, shelters, and trainers have been saying the same thing for years.

The shelter game-changer.
Built for the toughest environments on earth.
Built to Last
Standard tennis balls are shredded in minutes, creating choking hazards. Handcrafted from 100% natural rubber, WUNDERball stands up to the most aggressive shelter chewers.
Sanitary & Safe
Shelters are high-bacteria zones. Unlike porous toys that trap germs, WUNDERball is top-rack dishwasher safe — staff can sanitize and reuse them safely for every new resident.
Cognitive Enrichment
The unpredictable "Wacky" bounce provides vital mental stimulation. It keeps bored dogs sharp, alert, and engaged — key traits that catch an adopter's eye.
Bonus: natural rubber gently scrubs teeth to fight "shelter breath," making dogs even more kissable for adopters.
