WUNDERball + WUNDERleash = The Ultimate Dog Day
Pair the WUNDERball with a WUNDERleash (the original no-pull leash) for a calm walk to the park and an epic fetch session when you get there. The patented rubber leash stops pulling on the way — the WUNDERball burns off all that energy once you arrive. Walk calm. Play hard. Repeat.
You Asked, We Answered
Is the WUNDERball really indestructible? +
We say “virtually” indestructible because no toy on earth is truly indestructible if a determined dog goes at it long enough. But the WUNDERball is solid natural rubber — not hollow, not foam-filled, not fabric-covered. Owners report many months to several years of heavy daily use. It’s the toughest fetch ball we’ve ever made, and over 500,000 dogs agree.
Why is the bounce so unpredictable? +
The WUNDERball is handmade from natural rubber, so each one has a slightly irregular shape. That irregularity is the secret — every time it hits the ground, it bounces in a different direction. Your dog can’t predict where it’s going, which turns fetch from a straight-line sprint into a full mental and physical workout. It’s the difference between boring and obsessive.
Are tennis balls actually bad for dogs? +
Yes. The fuzzy felt on tennis balls is abrasive — it acts like fine-grit sandpaper on your dog’s tooth enamel, especially when they chew on it repeatedly. Over time, this wears teeth down significantly. Tennis balls also collect dirt and grit that makes it worse. On top of that, the glue and dyes used in tennis balls aren’t designed to be safe for dogs. The WUNDERball is 100% natural rubber, non-toxic, and gentle on teeth.
Does it really float? +
It does. Natural rubber is naturally buoyant, so the WUNDERball floats on the surface — pools, lakes, rivers, the beach. It’s easy to spot in the water and easy for your dog to grab. No more losing balls to the bottom of the lake.
What size should I get? +
Match the ball to your dog’s weight: Small (~2″, up to 15 lbs), Medium (~2.5″, up to 40 lbs), Large (~3″, up to 80 lbs), or XL (~3.5″, over 80 lbs). Each WUNDERball is handmade, so sizes are approximate. When in doubt, size up. A slightly larger ball is safer and easier for your dog to carry. The ball should be big enough that your dog can’t accidentally swallow it.
Can I use it indoors? +
Absolutely — the WUNDERball is great for indoor play, especially on rainy days or when your dog needs to burn off energy. The rubber won’t scratch hardwood floors and it’s soft enough not to damage furniture. Fair warning: the unpredictable bounce is even more entertaining (for your dog) when it ricochets off walls.
Is it really dishwasher safe? +
Yes — top shelf. Natural rubber handles the heat and water pressure just fine. After a muddy park session, a trip to the lake, or just a few hours of heavy slobber, toss it in the dishwasher and it comes out clean and sanitized. You can also hand wash it with soap and warm water if you prefer. Either way, it dries fast and is ready to go again.
Does it actually help clean my dog’s teeth? +
Every time your dog bites into the WUNDERball, the textured rubber surface works against their teeth to help remove plaque and tartar buildup while massaging the gums. It’s not a replacement for brushing or dental chews, but it’s a bonus you won’t get from a tennis ball — which actually damages teeth with its abrasive felt coating. The WUNDERball gives your dog a cleaner mouth just by playing.
