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 tires the legs while the head stays wide awake.
A herding ball gives a big dog something closer to real work. An object to push and steer, rather than catch and shred. Large breeds bring two complications. The jaw finishes cheap toys in a single session, and the size has to be right or the game never starts at all. This guide covers both.
Why a big dog can't use a medium ball
The mechanism is simple. If the dog can grip the ball in her jaws, it turns into a fetch toy, and from there into a chew toy. If she can't grip it, she has to move it with her nose, chest and shoulders. That is herding behaviour, and it's the whole reason the ball exists.
A German Shepherd or Rottweiler head fits around a 55 cm ball without much trouble. Even 75 cm is borderline for a big male. The 95 cm size exists for this group of dogs, who are large and strong enough to get their jaws around everything smaller.
The size rule
We size by shoulder height rather than breed name, because individual dogs vary too much for a label to decide it.
| 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 threshold is 63 cm and up at the shoulder, or roughly 34 kg and up, which puts them on the 95 cm ball. Below that, 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. For the smaller sizes and the measuring method, see what size herding ball does my dog need.
Breed by breed: the big four
The four breeds below turn up most often in the questions we get about the 95 cm ball. They use it in noticeably different ways.
German Shepherd
The classic case. A Shepherd without a task hires herself: patrolling the fence line, monitoring the street, escalating at the doorbell. A herding ball turns that patrol energy into push work. She drives the ball 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. Boredom is usually what sends people looking for one, and there is more on that in mistakes most people make with a German Shepherd.
Belgian Malinois
Highest drive on the list. A Malinois won't need two weeks to warm up. She'll work the ball hard from the first session and she won't stop on her own, so your job is ending the session rather than starting it. A Mali is also the most likely of the four to test the cover with her teeth. The 95 cm is the standard call here too. If yours measures clearly under 63 cm at the shoulder, measure before you order.
Rottweiler
The Rottweiler is a droving breed. It moved cattle for centuries by leaning into them, and that is roughly how most Rottweilers use a herding ball: less sprinting, more shouldering it across the garden. It looks unspectacular and it tires her out properly. One warning. A Rottweiler bites hard enough that a bare inflatable ball is money wasted, so don't run that experiment first.
Dobermann
Fast and light on her feet for her size. A Dobermann plays the ball more like a Malinois than a Rottweiler: sprint after it, cut it off, push again. The FCI breed standard puts males at 68–72 cm and females at 63–68 cm at the shoulder, so the 95 cm is the standard call. She carries less coat and less padding than the others here, which makes grass over pavement matter more for her than for a Rottweiler.
What a strong jaw does to a cheap ball
This is the part that decides whether the purchase makes sense. Gym balls are the usual budget substitute, and a gym ball is a single layer of PVC. One bite through the skin and it's finished, often on day one. If you own one of these breeds, you have probably run that loop already.
A CollieBall is two parts instead of one: an inflatable inner ball, and a ballistic fabric cover over it, so teeth and claws meet the cover and never the air chamber. The construction is explained in full on the herding ball page.
The cover is built for the toughest chewers, and it is the part doing the work at this size. The cover and the inner ball also come apart, which means a damaged inner costs you one component rather than a whole new ball. For a large-breed household that is the design decision that matters most.
Running sessions with a heavy dog
Ten to fifteen minutes is a real session for a 40 kg dog, and two short sessions beat one long one. A Malinois will lobby for more. Don't negotiate.
Grass or compact dirt is the surface you want. Concrete grinds the cover down faster and is harder on a heavy dog, so keep it brief if a paved courtyard is all you have.
End every session on a cue while she's still keen, then put the ball away. A ball that is always out becomes background furniture, and with these breeds it also becomes unsupervised chewing time. Fifteen minutes at a time keeps it interesting for years.
The honest downsides
It's big. A 95 cm ball is furniture-sized and doesn't collapse for storage, so you need a garage corner, a shed or a covered spot outside. Measure that spot before you order. Storage catches more first-time owners than anything else on this list.
It needs a compressor. Filling 95 cm by hand isn't realistic, so budget for a pump you can plug in.
It isn't silent. A Rottweiler banging a ball off a metal fence at 7 a.m. will get you talked about. Think about where and when the sessions happen.
Not every dog switches on immediately. Plenty of Shepherds inspect the thing for days before the first real push. That's normal. Give it two weeks of low-pressure exposure before you judge.
It isn't for growing or injured dogs. A large-breed puppy shouldn't do full push sessions until she has finished growing, and a dog with a diagnosed joint problem needs a vet's opinion before any new activity. It's a toy, not a treatment.
So is the 95 cm right for your dog?
If she stands 63 cm or more at the shoulder, or if she simply grips every smaller ball in her jaws, the 95 cm herding balls are the size built for her. Ballistic cover outside, replaceable inflatable inner, dimensioned so a large breed can't get purchase with her teeth. The 95 cm complete package comes with the cover, the inner ball and a carry bag. Still torn between a 75 and a 95? One measurement and the size guide settles it.
CollieBall is the original herding ball, designed in San Francisco, first built in 2021, with over 1,000 orders worldwide.
