Frequently asked questions

FetchSphere is an interactive dog ball that moves on its own. A motor inside makes it roll, bounce and change direction by itself, so your dog can chase it without anyone throwing it. It comes in three sizes: the Pro for medium and large dogs, the Mini for small dogs and puppies, and the Nano for cats and very small dogs. Every ball recharges over USB-C.

The Pro (3.1 in / 80 mm, 170 g) is for medium and large dogs, about 25 lb and up: pit bulls, retrievers, huskies, shepherds. The Mini (2.7 in / 69 mm, 160 g) is for small dogs under about 25 lb, puppies and seniors. The Nano (2.4 in / 61 mm) is for cats, kittens and very small dogs. The Nano is too small for medium or large dogs, who could swallow it.

Yes. There is no app, no remote and nothing to throw. Press the power button and the ball rolls, bounces and changes direction by itself. After about 10 plays it rests to save battery, then wakes up the moment your dog bumps it.

The Pro has three: Chill (slow, gentle rolling), Play (balanced bouncing for everyday fun) and Beast (fast and erratic for high-energy dogs). Tap the power button to cycle through them. The Nano has two, Chill and Beast, with a rainbow paw light. The Mini has one automatic mode: it rolls and bounces on its own with a light-up LED rim.

For dogs 25 lb and up that chew hard, pick the Pro. Its shell is bite-resistant E-TPU: soft enough not to chip teeth, dense enough to resist punctures. No toy is indestructible, so supervise heavy chewers and stop using the ball if the shell is badly damaged. If your dog chews through it within 30 days, we refund you.

The Mini. It is 2.7 in across, sized for small mouths, and its LED rim lights up while it rolls. We recommend it for dogs 6 months and older. It is not a teething toy.

Yes, the Nano. It is 2.4 in across, has two modes (Chill and Beast) and a rainbow paw light, and is sized for cats, kittens and very small dogs.

That is what it is built for. The ball starts moving when your dog bumps it and rests after about 10 plays, so your dog decides when to play. Like any toy, we do not recommend leaving a heavy chewer alone with it unsupervised.

No. There is no app, no Bluetooth pairing, no remote and no subscription. Charge it, press the power button and it plays.

The Pro and Mini shells are bite-resistant E-TPU: soft enough not to chip teeth, dense enough to resist punctures. The outer shell twists off for cleaning. We back it with a 30-day chew guarantee: if your dog chews through it in the first 30 days, you get a full refund.

After about 10 plays the ball rests to save battery. The built-in touch sensor wakes it the moment your dog bumps it, so nobody has to switch it back on by hand. It works the same way on the Pro, Mini and Nano.

Absolutely, it is a popular setup. Build a 2-pack and pick any combo, even a Pro in one color and a Mini in another. Any 2-pack saves you $20 off the single prices.

The Pro and Mini run for about 3.5 hours of active play on a full charge. The Nano runs for about 4 hours. All three charge over USB-C with the included cable.

Yes. Hardwood, carpet, tile and grass all work. Beast mode is most dramatic on hard surfaces.

Yes. The outer shell twists off in about 5 seconds. Replacement shells in more colors are on the way: one core, endless looks.

The Pro and Mini are rated IP54, which means splash-proof. You can rinse them under running water to clean them. The Nano is water resistant: wipe or rinse the shell. Do not submerge any of them in a pool or run them through the dishwasher.

The one that fits the dog. For a medium or large dog, 25 lb and up, or a power chewer, you want about 3 inches across with a thick bite-resistant shell and more than one speed: that is the FetchSphere Pro. For a small dog or puppy under 25 lb, a lighter 2.7 inch ball with a light for evening play: the Mini. For a cat or a dog under about 8 lb, a 2.4 inch ball: the Nano. Whatever you buy, look for a shell that fails slowly, a rest cycle so the dog is not chasing to exhaustion, and no app to babysit. Our buying guide on the blog compares the options in detail.

Yes, with two rules. Size up: the ball must be bigger than the gap behind your dog’s back teeth, which is why the Pro is 3.1 inches and the Nano is for cats and very small dogs only. And treat it as a chase toy, not a chew bone: check it weekly, retire it if a chunk comes off, and supervise a heavy chewer. The built-in rest cycle stops the ball after about 10 plays so your dog gets short bursts of play rather than an hour of frantic running.

Boredom, yes. A ball that starts when your dog nudges it gives a home-alone dog short chase sessions through the day, which is the kind of busy that ends in a nap. Separation anxiety is different: panic at the door, drooling, destruction at exits. No toy fixes that, and a trainer or vet is the right call. Our blog post on dog toys for boredom has a simple work-day plan.

Three sizes, one for each pet: the Pro for medium and large dogs, the Mini for small dogs and puppies, the Nano for cats. A bite-resistant E-TPU shell on the Pro and Mini, built for Bay Area dog park dogs rather than gentle chewers, backed by a 30-day chew guarantee. A rest-and-wake cycle so the dog decides when to play. No app, no Bluetooth, no subscription. And every 10 balls sold, we give one to a random dog. We publish an honest side-by-side with the best known competitor on the blog, including where they are the better pick.

Free US shipping on every order, and it ships from the USA. Standard delivery is typically 5 to 10 business days.

30-day happy-tail guarantee. If your dog does not love it, email support@fetchsphere.com for a full refund, no questions asked.
