Canicross for beginners: running with your dog without hurting it

Canicross is running as a pair, attached to your dog by an elastic line. The sport has its rules, set in France by the Fédération française des sports et loisirs canins, and precautions that mainly protect the dog. Here is the kit, the age at which a dog can start, the first runs, the overheating and injuries to avoid, and why a club is the easiest way in.

Running as a pair, joined by a line

As much as 2 to 4 km/h faster. That is the boost a dog can give its runner in canicross, according to the Fédération française des sports et loisirs canins (FFSLC), France’s federation for dog sports: a form of running in which runner and dog are joined by a line with a shock absorber, and in which speed depends above all on the bond between the two [1].

Under the French federation’s rules, the sport is open to everyone and to every breed of dog, except dogs classed in category 1 under French law [8]. Spiked shoes are strictly banned, so as not to injure the dogs, and races are 5 to 9 km long depending on the temperature [1]. If you race outside France, check the rules of the event you enter.

The kit: harness, belt and bungee line

The French federation makes the point: specialised equipment is essential, namely a harness, a belt with leg loops, a waist belt and a towline [1]. Each piece has its job.

Based on the Fédération française des sports et loisirs canins and Decathlon’s advice for beginners.

The harness is the piece that matters most: it is a long harness, designed so that the dog can pull in comfort, and it must fit the dog’s build [2]. Clubs often lend kit, so you can try several harnesses before you buy [2].

How old does a dog need to be for canicross?

For racing in France, the federation’s rule is clear: a dog must be 18 months old to start competing [1]. For leisure training, age is not everything: a young dog, even at 18 months, starts with very short distances [2]. A check-up at the vet before you begin will show whether its heart, joints and paw pads are ready for the effort.

The first runs, step by step

  1. Run without the canicross kit at first, so that your dog finds its pace beside you, and teach it the basic command: stop [2].
  2. Then put the kit on and jog gently: the dog will usually move out in front. Before a turn, say ‘left’ or ‘right’ while steering the line that way [2].
  3. Build up very gradually: for an 18-month-old dog, 500 m of pulling, then 700 m, then 1 km [2].
  4. Start and finish each outing with a short stroll off the lead, where that is allowed, so your dog can warm up, unwind and relieve itself [2].

The ground matters as much as the distance. Stick to paths and forest tracks, which are soft on paws, and avoid tarmac and concrete: that is asking for an injury. Stop every quarter of an hour to give your dog a drink, with a water bottle and its bowl in your rucksack, and keep an eye on its breathing: if it seems very out of breath, slow down or stop [2].

Overheating: the number one danger, even in winter

In the UK, researchers reviewed the records of more than 900,000 dogs under primary veterinary care in 2016 and identified 1,259 cases of heat-related illness, or heatstroke. Where the trigger was recorded, exercise accounted for 74.2% of them, against 5.2% for confinement in a hot vehicle: exertional heatstroke affected around ten times as many dogs as hot cars did, and caused eight times as many deaths. Nor is it only sporty dogs: where the type of exercise was recorded, two cases in three followed a simple walk. Young males were more at risk of it, and brachycephalic (flat-faced) dogs, such as bulldogs, were more at risk from all three main triggers [3].

Environmental (hot weather)11312.9%
Vehicular confinement465.2%

Building confinement242.7%
Blanket entrapment40.5%

Source: Hall, Carter and O’Neill, 2020. Of the 1,259 cases found in the records of dogs under veterinary care in 2016, 380 had no trigger recorded; the shares are of the other 879.

Running in winter is no protection. In another study, researchers took the temperature of 108 dogs at the finish of ten British canicross races, run in feels-like temperatures of -5 to 11 °C. At every race, some dogs went above 40.6 °C, the point beyond which a prolonged high temperature is likely to cause heatstroke: 30 of the 281 readings did. Male dogs, dark-coated dogs and the fastest runners were the most at risk [4].

The danger does not stop at the finish line. In a third study, also at British races, the dog’s temperature kept rising during the five minutes after exercise in nearly one case in four (24.4%). Dogs put straight into a vehicle cooled down less well, whereas immersion in water at 0 to 15 °C cooled them effectively, with no adverse effects. The researchers’ advice fits on one line: ‘cool first, transport second’ [5].

The most common injuries, for your dog and for you

The first survey devoted to canicross injuries, published in 2018 from the responses of 160 participants, gives an idea of the risks: 21.9% of the dogs had been injured at least once. Lacerations, abrasions and punctures came top, most often on the pads of the front paws, and most dogs had recovered [6].

Runners are not spared either: 69 of the 147 handlers surveyed had been injured while racing, most often at the ankle. Among the dogs, three profiles were injured more often: those running with another dog, those also competing in agility, and purebred Labradors [6]. So it is wiser to start with a single dog, on paths without sharp stones, and to check its pads after every outing.

Races, children and clubs

Canicross is a family sport too. In France, the federation scales distances to children’s ages and requires an adult to be present for the youngest; an adult can also run attached to the dog, a little behind the child, if the dog is too powerful for the child’s size [7].

FFSLC categoryAgeMaximum distance
Benjamins7 to 9 years1.5 km, with an adult required
Minimes10 to 12 years2.5 km
Cadets13 to 14 years3.5 km
Juniors15 to 18 yearsRace with the adults

The easiest way to start is to join a club: according to the sports retailer Decathlon, there are more than 250 in France, and they give good advice as well as lending kit [2]. If you already run on your own, our training plan for a first trail race sets out the principles of a gradual build-up: they apply to your dog too.

FAQs

How old does a dog have to be for canicross?

To race in France, the Fédération française des sports et loisirs canins requires dogs to be at least 18 months old. For leisure training, start with very short distances too, 500 m, then 700 m, then 1 km of pulling, and it is wise to have a vet check that your dog is fit for the effort.

What kit do I need for canicross?

Three pieces: a pulling harness that fits your dog’s build, a waist belt, or a belt with leg loops for a very powerful dog, and a line with a shock absorber connecting the two. Spiked shoes are banned in races in France. Clubs often lend kit, so you can try before you buy.

Can you do canicross in hot weather?

Best not. Above 20 °C, the advice is to postpone your run, because overheating can be fatal for a dog and hot ground can injure its paw pads. Run early in the morning or in the evening, in the shade, with water, and stop as soon as your dog seems very out of breath.

Can a dog get heatstroke in winter?

Yes. At ten British canicross races run in feels-like temperatures of -5 to 11 °C, dogs finished above 40.6 °C at every race, a dangerous threshold if it lasts. Male dogs, dark-coated dogs and the fastest runners were the most at risk. After exercise, cool your dog in the open air or in cold water before putting it back in the car.

Can children do canicross?

Yes. In France, the Fédération française des sports et loisirs canins sets suitable distances: 1.5 km at most for 7 to 9-year-olds, who must have an adult with them, 2.5 km for 10 to 12-year-olds and 3.5 km for 13 to 14-year-olds; juniors race with the adults. An adult can also be attached to the dog if it is too powerful for the child.
