A German Shepherd with nothing to do will invent a job. Usually one you won't like: fence-running, shadow-chasing, digging a trench along the hedge. Large working breeds were bred for hours of purposeful work, and a walk around the block doesn't come close to covering it. The muscles get exercise. The head doesn't.
A herding ball is one of the few toys that gives a big dog actual work — something to push, steer and control instead of catch and shred. But large breeds bring two problems most balls can't survive: a jaw that finishes cheap toys in one session, and a body that needs the right size for the game to work at all. This guide covers both.
Why a big dog can't use a medium ball
The whole mechanism of a herding ball depends on one thing: the dog can't pick it up. A ball she can grip in her jaws becomes a fetch toy — carried, chewed, punctured, forgotten. A ball too big to grip has to be moved with the nose, chest and shoulders. That's the point where herding behaviour starts and chewing behaviour stops.
For a German Shepherd or Rottweiler head, 55 cm sits well inside bite range. Even 75 cm is borderline for a big male. The 95 cm size exists for exactly this group: dogs large and strong enough to get their jaws around everything smaller.
The size rule
We size by shoulder height, not breed name. Individual dogs vary too much for breed labels alone.
| Shoulder height | Ball size |
|---|---|
| Up to 37 cm | 45 cm |
| 38–50 cm | 55 cm |
| 51–62 cm | 75 cm |
| 63 cm and up | 95 cm |
For the breeds in this guide, the practical threshold is simple: 63 cm and up at the shoulder, or roughly 34 kg and up, take the 95 cm ball. Below that, the 75 cm is usually right. If your dog sits on the line, size up — a ball slightly too big still works, a ball slightly too small ends up in her mouth. The full measuring logic is in the size guide.
Breed by breed: the big four
These are the large breeds we see most often on the 95 cm ball. They use it in noticeably different ways.
German Shepherd
The classic case. A Shepherd without a task defaults to self-employment: patrolling the fence line, monitoring the street, escalating at the doorbell. A herding ball converts that patrol energy into push work — she drives it along the fence with her chest and nose, which is close to what her breeding asks for. The 95 cm is the standard call for the breed. If your Shepherd measures clearly under 63 cm at the shoulder, measure first and let the size guide decide.
Belgian Malinois
The highest-drive dog on this list. A Malinois doesn't need two weeks to warm up to the ball — she'll work it hard from the first session, and she won't stop on her own. Your job is ending the session, not starting it. A Mali is also the breed most likely to test the cover with her teeth, so the two-layer construction earns its keep here more than anywhere. The 95 cm is the standard call for a Malinois too. If yours measures clearly under 63 cm at the shoulder, measure first and let the size guide decide.
Rottweiler
People forget the Rottweiler is a droving breed — it moved cattle for centuries by leaning into them. That's exactly how most Rottweilers use a herding ball: less sprinting, more body-checking it across the garden with chest and shoulder. It looks unspectacular and tires her out properly. One warning: Rottweiler bite strength is at the top end of any common breed. A bare inflatable ball has no chance. Don't bother trying one first.
Dobermann
Fast and light on its feet for its size. A Dobermann plays the ball closer to a Malinois than a Rottweiler — sprint, steer, cut it off, push again. Most Dobermanns stand 63–72 cm at the shoulder, so the 95 cm is the standard call. She has less coat and less padding than the others on this list; grass over pavement matters more for her than for a Rottweiler.
Durability, without the marketing voice
Here's the part that decides whether this purchase makes sense. A strong-jawed dog destroys a cheap ball fast. Gym balls — the usual budget substitute — are a single layer of PVC. One bite through the skin and it's done, often on day one. Owners of these breeds know the cycle: buy ball, dog kills ball, repeat.
A CollieBall is built as two separate parts: an inflatable inner ball, and a cover of ballistic fabric over it. The cover takes the teeth, the claws and the ground. The inner just holds air, and teeth never reach it directly.
No ball is indestructible, and we're not going to claim ours is. What we can say concretely: the cover is made to take sustained punishment from exactly these jaws, and if the inner ball is ever damaged, you replace the inner alone — not the whole ball. For a large-breed household, that replaceable inner is the design decision that matters most.
Running sessions with a heavy dog
Keep sessions short. Ten to fifteen minutes is a real session for a 40 kg dog; two short sessions beat one long one. A Malinois will lobby for more. Don't negotiate.
Pick the surface. Grass or compact dirt. Concrete grinds the cover down faster and is harder on a heavy dog. If a paved courtyard is all you have, keep it brief.
Teach an off switch. End every session while she's still keen, on a cue, and put the ball away. A ball that's always available becomes background. A ball that appears for fifteen minutes stays interesting for years — and with these breeds, "always available" also means unsupervised chewing time.
The honest downsides
- It's big. A 95 cm ball is furniture-sized and doesn't collapse for storage. You need a garage corner, a shed or a covered spot outside. Measure that spot before ordering — this is the number-one surprise for new owners.
- It's not silent. A Rottweiler banging a ball off a metal fence at 7 a.m. is a neighbourhood event. Plan where and when the sessions happen.
- Not every dog switches on immediately. Some — including plenty of Shepherds — inspect the ball for days before the first real push. Normal. Give it two weeks of low-pressure exposure before you judge.
- It's not for growing or injured dogs. A large-breed puppy shouldn't do full push sessions until she's finished growing, and a dog with a diagnosed joint problem should get a vet's opinion before any new activity. It's a toy, not therapy.
So is the 95 cm right for your dog?
If she stands 63 cm or more at the shoulder — or simply grips every smaller ball in her jaws — the 95 cm herding ball is the size built for her. Same two-layer construction as the smaller sizes: ballistic cover outside, replaceable inflatable inner, dimensioned so a large breed can't get purchase with her teeth. Not sure whether she's a 75 or a 95? The size guide settles it with one measurement.
CollieBall is the original herding ball — designed in San Francisco, first built in 2021, with over 1,000 orders worldwide. Most of those big dogs figured the ball out inside a week. Yours probably will too.
