The Flexiness® Donut is an inflatable, donut-shaped training tool built for rehabilitation and advanced canine fitness exercises. Its smooth surface keeps the work controlled, and its shape invites the dog to stand, sit, lie down or side-step on it.

The donut moves slightly under the dog’s weight, so the center of gravity keeps shifting, and the dog has to keep adjusting through core and limb muscles to stay in position.

Need a bit more stability while still challenging core control and balance? Place the Donut inside an upside-down Flexiness® PawStep.

Compared with the SensiDonut, it’s smaller and has no nubs, so the focus stays on balance and control rather than sensory input.

Who it’s for:
All levels, ages and sizes. The exercise sets the difficulty, not the tool, so you adjust the setup to your dog.

How it's used by size (see breed guide):

Toy: all 4 paws
Small: front or hind paws; most small breeds all 4 paws
Medium: front or hind paws
Large: front or hind paws
Giant: front or hind paws

How to start

Posture Check:

Level topline (according to the breed)
Neutral head position
Neutral limb position: front limbs vertical under the chest (depending on the exercise)
Hind limbs in a moderate position, not under the body.

Every dog starts from a different point. Before you begin training with Flexiness® equipment, make sure your dog is healthy and fit for the work you have in mind. If you’re unsure, or if your dog is recovering from an injury, check with your veterinarian or canine physiotherapist first.

Important:
Start on stable equipment and add instability once your dog can control the position.
Use on a non-slip floor or surface and keep the training area free of sharp objects.

Check Basic Exercises for inspiration.

Customer Reviews

Overall rating: 5 / 5 from 7 reviews.

I absolutely love the Flexiness TwinDisc! One of my favorite features is its low profile design, which makes it a wonderful piece of equipment for introducing dogs to balance and stability exercises without requiring them to step onto a higher surface. It’s incredibly versatile and allows me to incorporate a variety of exercises that encourages body awareness, coordination, balance, and controlled movement. I especially appreciate how easily it can be incorporated into fitness routines for dogs of different sizes and abilities. As a certified Canine fitness trainer I love finding equipment that is both functional and approachable for the dogs. The TwinDisc has quickly become one of my favorite pieces of fitness equipment. I will be ordering another one soon.

It really makes a difference. Improves strength, balance, agility and coordination. Our dog loves it!

My 3 years old working cocker Taboo and I absolutely love our new equipement from Flexiness 😍 we use it 3 times a week for our fitness training and I'd totally recommend this to everyone. It's so usefull and easy that you can stack them and have the set up that you need in a safe way!

I really like the quality of the TwinDisc. The material feels sturdy, and the textured surface gives the dogs good feedback under their paws. I especially like its low profile, as it keeps the dogs close to the ground while still giving them a different surface to work on. It holds its shape during our training sessions, so I can focus on Rocky’s posture and weight distribution without worrying about the equipment giving way.

TwinDisc

Ich verwende den FlexBloxWedge regelmäßig in der Rehabilitation und zur Prävention, auch in Kombination mit anderen Trainingsgeräten. Bei regnerischem Wetter setze ich ihn außerdem für das Cross-Training von Sporthunden ein. Ich bin sehr zufrieden damit: Er ist stabil, lässt sich schnell umpositionieren und flexibel zu verschiedenen Trainingsaufbauten kombinieren. Wenn ich einen Kritikpunkt nennen müsste, dann höchstens, dass ich mir eine größere Farbauswahl wünschen würde.

A few days ago, my order arrived (1 TwinDisc and 2 StackingBars), and I have to say, I already absolutely LOVE them! The only thing I regret is not ordering two TwinDiscs right away!

TwinDisc

My absolute fav is the TwinDisc, it's sooo comfy to use with big dogs, it's wide enough and much much more stable than a bone shaped surface. For rehab I love it bc as I said it's wide enough, so encourages dogs to step on it, in my experience with other discs they try to cheat and go around and not step on the disc. The TwinDisc solves this problem for me. + it's awesome for dogs who come to rehab bc it's a good platform for beginner exercises but it makes a perfect choice for the pro fitness dogs and beginners in rear end targeting as well.

The TwinDisc V2 and PawDisc are my favorite Flexiness products. Both provide instability but remain in place; I don't have to worry about them flipping or sliding if my dog is slightly off-center. And the material is absolutely wonderful; very flexible with excellent traction. Their size is appropriate for use as a 2-foot target with almost all dogs, and small dogs can stand on them with all 4 feet.

We started from zero and had no idea where to begin. With Flexiness equipment, we’re having fun learning together, trying new things, and celebrating the little improvements. Seeing my dog become more confident with every session is the best part!

I use SensiMat and TwinDisc (very stable piece of instability) for my spaniel as part of his balance track work and the SensiMat is invaluable for my neuro-deficient patients.

We love the SensiMats. We use them every day!

Oh gosh I love it all! The TwinDisc V2 are amazing and have been integral to my dog's fitness and rehab. The PawDisc is also wonderful, you can do so many exercises with just that one piece of equipment!

A few days ago, my order arrived (1 TwinDisc and 2 StackingBars), and I have to say, I already absolutely LOVE them!
The only thing I regret is not ordering two TwinDiscs right away!

I absolutely love PawDisc, because its surface is straight, not convex. It means the dog's paws and whole limbs are even and muscles don't have to deal with balancing the convex surface. I also like that it has fine lines. I believe it is better for some dogs.

Love the StackingBars! We definitely need to add more Flexiness equipment to our rotation. Top quality!

The best time to start is now

Progress comes from a setup your dog can control, repeated until the position holds without compensating. Start simple: one defined demand and a few minutes of clean technique. Then change one variable at a time: height, angle, surface or an additional tool. Add the next only when the current one is under control. That way every new setup builds on the last.

The Donut (30x50cm) fits right into that progression.

Why Flexiness?

BUILT AROUND THE DOG

Every Flexiness® training tool starts with canine anatomy: how a dog shifts its weight, where control is missing, what changes when a paw lands on a new surface.

TESTED, THEN PRODUCED

Every design is tested on real dogs before it goes into production. A good idea isn’t the same as a good training tool.

NO REPURPOSED EQUIPMENT

Each tool is designed for four legs, a long spine and a body that carries most of its weight up front, so the exercise trains what it’s meant to.

TOOLS AND INSPIRATION

Almost every tool combines with the rest, so your setup grows with your dog. Exercises show you what each setup can do, giving you the right tools and the ideas to use them.

Strength

Strength is what keeps your dog’s body stable when it moves, jumps, turns or simply gets up. Targeted exercises load specific muscle groups, like the core, hind end or front end, in a controlled way, so the body learns to carry load without compensating. Stable training tools like the FlexBlox system set the height and angle that make that load precise.

Balance

A dog with good balance stays in control when the ground shifts, on slippery floors, uneven terrain or a sudden change of direction. On unstable training tools like the PawDisc or TwinDisc, the body makes small, constant adjustments through the paws, legs and trunk. That trains the ability to stabilize, not just to stand still.

Coordination & Body Awareness

Many dogs don’t really know where their hind legs are. You see it when they knock bars, trip on stairs or step carelessly. Paw stacking with tools like the PawStackers or StackingBar, and the sensory input of the SensiMats, make every paw placement deliberate. The result is a dog that moves each leg with intent instead of on autopilot.

Posture

How your dog stands tells you how it will move. A balanced, aligned stance distributes weight evenly and gives every movement a stable base. Stable training tools help your dog find and hold that position, and the balanced stand is the exercise everything else builds on.

Confidence & Connection

A dog that trusts its own body approaches new surfaces, heights and situations with curiosity instead of hesitation. Every exercise is a small, solvable task: your dog thinks, tries and works out where each paw goes, while you read its body and set the next step. That builds confidence one success at a time, and a shared language between the two of you that carries into everyday life. Clear targets like the PawTargets and stable platforms make those successes easy to set up.
