Cycling with your dog is not bad for their joints if your dog is fully grown, fit, lean and built for running, and if you keep them at a steady trot on soft ground. It becomes hard on joints when a dog starts too young, is pushed into a long gallop to keep up, runs on tarmac, or goes too far too soon.
The risk comes from the bike as much as the dog: you can hold a pace for an hour without effort, and a keen dog will try to match it whether their body is ready or not.
Joint Support for Dogs That Run Beside a Bike
A dog that runs beside a bike covers a lot of ground in one session, so many owners add daily joint support to their routine. Here is how the UK's best-known supplements compare on the key joint actives.

How Old Should a Dog Be Before Running Beside a Bike?
Running beside a bike is sustained, repetitive exercise, so the main joint concern for young dogs is growth plates: the soft zones near the ends of the long bones that only harden and close once a dog has finished growing. Hill's advises waiting until your dog has finished growing before you cycle together, and notes that large breeds can take up to two years to mature.
The UK club Canicross Trailrunners sets 18 months as the minimum age for its bike discipline, and Dogfit, a UK dog fitness specialist, recommends erring on the side of caution and aiming for around 18 months, with a vet check first. Faster pulling sports such as bikejoring add speed and load, which is why they sit at the top of that age range.
- Small and medium dogs: wait until they are fully grown, and for the faster pulling disciplines treat 18 months as the minimum.
- Large and giant breeds: expect to wait longer, and ask your vet to confirm your dog is skeletally mature.
- Before then: teach cues such as "steady", "left" and "right" on walks.
If you have a big-breed youngster, our guide to protecting large-breed puppy joints explains why patience pays off.
Pace: Keep Your Dog at a Trot
The trot is the gait that matters most. It is the efficient, steady, two-beat gait dogs can hold for long periods, and it is the pace that advice on cycling with dogs keeps coming back to: keep your dog at a trot, not a run. The pet product maker flexi, for example, describes a trot or jog as the pace that is gentlest on the joints.
A gallop is a sprint gait that loads the front legs, shoulders and back far more with each stride. If your dog has to gallop to keep up, you are going too fast.
- Ride at your dog's pace, not yours. For many dogs that is a gentle cycling speed.
- Build in walking breaks, especially in the first few minutes and on hills.
- Do not tow your dog uphill or let them chase you downhill. Get off and walk steep sections.
Kit and Set-Up
Never hold a lead in your hand while riding. The Highway Code tells cyclists not to carry anything that may get tangled up with their wheels or chain, and a sudden lunge can pull you off and drag your dog.
Casual riding with a springer or bike attachment
For riding at a trot with your dog alongside, use a rigid bike attachment (often sold as a springer) that clips to the frame and holds your dog at a fixed distance from the wheel. Pair it with a well-fitted harness rather than a collar, so any jolt goes through the chest rather than the neck.
Bikejoring kit
In bikejoring your dog runs out in front and pulls. Dogfit lists a well-fitting pulling harness, a bungee line of at least 2.8m when stretched, and a bike antenna to keep the line clear of the front wheel, on a mountain bike with disc brakes. The bungee acts as a shock absorber for your dog's shoulders and spine every time the pace changes.
Surfaces, Distance and Heat
How common cycling surfaces affect a dog running alongside
| Surface | Joint and paw impact | Tips |
|---|---|---|
| Grass and earth tracks | Low, with some cushioning | Best starting point. Watch for ruts and rabbit holes. |
| Woodland single track | Low, but uneven | Slow down for roots and tight bends. |
| Gravel and flinty trails | Moderate, hard on pads | Use sparingly and check paws after every ride. |
| Tarmac and roads | High and repetitive, can get very hot | Keep to short links between off-road sections. |
| Deep mud or long wet grass | Tiring, with a risk of slips and twists | Avoid in early sessions. |

Building distance
Start very short. Canicross Trailrunners suggests a first bike interval of 200m and builds towards 5km over a training plan, while Dogfit says even 100m in harness is a great start, with one short session a week in the early stages. For casual riding with a springer, a few minutes of trotting between walking breaks is plenty at first. Add a little at a time and let your dog's recovery the next day decide whether to go further. Our guide to whether you can over-exercise your dog explains how to judge it.
Heat
A dog running beside a bike works hard and cools mainly by panting. Dogfit advises bikejoring below 15°C, taking humidity into account, with shorter sessions than you would run on foot. Cycling UK points out that dogs overheat at much lower temperatures than people. Ride early or late, choose shaded routes with water, and on warm days leave the bike at home.
Paws
Pads take a battering on rough or hot surfaces. Cycling UK advises keeping nails short and checking pads for abrasions after every ride, and flags flinty trails as being as tough on paws as they are on tyres. If your dog needs extra grip or protection, see our guide to dog boots and paw grips.
Which Dogs Suit Cycling, and Which Don't
Build matters more than enthusiasm. Hill's suggests medium and large dogs with lean bodies and long legs do best, naming breeds such as Border Collies, Rhodesian Ridgebacks, Siberian Huskies and Greyhounds. Dogfit adds that smaller athletic working breeds such as Cocker Spaniels can also excel.
Dogs that are usually better off with other exercise include:
- Flat-faced (brachycephalic) breeds, such as Bulldogs, Pugs and Boxers, which struggle with breathing and heat.
- Long-backed, short-legged dogs, such as Dachshunds, whose build is not designed for sustained running.
- Very large, heavy breeds, such as Newfoundlands and Saint Bernards.
- Overweight dogs, whose joints are already carrying extra load. Our guide to canine obesity and joint health explains why.
- Older dogs or dogs with stiff joints, which are usually better suited to walking, swimming or gentle off-lead time.
Signs Your Dog Is Finding It Too Much
Keen dogs will keep running long after they should stop. Hill's lists lagging behind, heavy panting, seeking shade or wanting to lie down as signs to stop.
From normal tiredness to a vet visit after cycling
Happy tiredness
Sleeps well after a ride, moves freely when they get up, and is keen to go again next time.
Lagging or lingering stiffness
Drops back behind the bike, breaks into a gallop to catch up, or is stiff the next morning. Cut the distance and pace for a week or two.
Lameness, sore pads or heat stress
Limping, holding a leg up, torn or bleeding pads, or heavy panting, wobbliness or collapse. Stop riding and get veterinary help.
If your dog comes home lame, our guide to dogs limping after exercise explains what to do next.
Where Joint Support Fits
A joint supplement will not make a young, heavy or unsuited dog safe to run beside a bike, and it is no substitute for a slow build-up and a sensible pace. What it can do is give a fit dog's joints a steady daily supply of the nutrients they use to maintain cartilage and joint fluid.
MedPaw Hip & Joint Chews Max is a soft chew given at 1 chew a day up to 4kg, 2 for 5 to 17kg and 2 to 3 for 18kg and over, doubled for the first three weeks. Allow 2 to 3 months for optimal results, so it makes sense to start well before you build up your riding.
When to See Your Vet
Book a check-up before you start cycling with your dog, especially if they are a large breed, older, carrying extra weight, or have had an injury. See your vet promptly if your dog:
- limps or holds a leg up during or after a ride, even briefly
- is stiff for more than a day or two after riding
- has swelling, heat or pain around a joint
- has cut, torn or bleeding pads
- shows heavy panting, drooling, wobbliness, vomiting or collapse, which can mean heatstroke and is an emergency
Is it bad for my dog to run beside my bike?
Not if your dog is fully grown, fit, lean and suited to running, and you keep them at a steady trot on soft ground and build up slowly. It is hard on joints if a dog starts too young, has to gallop to keep up, or runs long distances on tarmac.
What age can a dog start running with a bike?
Wait until your dog has finished growing. Hill's notes large breeds can take up to two years. UK club Canicross Trailrunners sets 18 months as the minimum for its bike discipline, and Dogfit recommends aiming for around 18 months with a vet check first.
How fast should I cycle with my dog?
Ride at a speed your dog can hold at a relaxed trot. If they have to gallop to keep up, slow down. Build in walking breaks and walk steep hills.
How far can my dog run next to a bike?
Start with very short intervals, around 100m to 200m, or a few minutes of trotting, and build gradually over weeks. Let your dog's recovery the next day guide how much you add.
