Daily walks and dog health: breed needs, age limits and heat

What walking does for the body

Regular walking is the simplest way to keep a dog moving, and some of the most striking evidence for staying active comes from aging dogs. In the Dog Aging Project, a large US study of companion dogs aged 6 to 18, owners who reported higher levels of physical activity also reported fewer signs of cognitive decline and lower odds of their dog reaching the clinical threshold for canine dementia. The study was a snapshot, so it cannot show that exercise caused the difference. A dog already slowing mentally may simply be walked less. Even so, the link held after the researchers accounted for age and other health conditions, and it points the same way as the human research on activity and dementia.

Walking also keeps muscles working and joints moving through their range, which matters most for dogs with arthritis or those carrying extra weight. Many dogs empty their bowels and bladders on a walk, and a regular routine makes toileting more predictable.

Walking helps with weight, but it does not replace portion control. A walk at a steady pace uses a modest amount of energy, and a few extra treats can cancel it out. Weigh the dog every few weeks, feel for the ribs, and adjust food first when the weight creeps up. The guide to signs your pet is overweight explains body condition scoring.

Walks, sniffing and behavior

Dogs gather most of their information about the world through their noses. A walk is often the only time a house dog meets new smells, and many dogs spend much of a slow walk investigating them. Letting a dog stop and sniff turns a walk from exercise into something the dog chooses and controls. Owners in a hurry tend to cut this part short, and it is worth building sniffing time into at least one walk a day.

Chewing, barking, pacing and trouble settling in the evening can reflect boredom, and a dog with too little to do is more likely to find its own outlet. The same signs can also come from anxiety, pain or a medical problem. If more walking and play do not help within a few weeks, a vet check is the next step, followed by a qualified behaviorist if the vet finds nothing.

Puppies and socialization

The window for socialization is much earlier than many owners assume. VCA Animal Hospitals describes the sensitive period as running from about 3 to 16 weeks of age, and points out that it has usually closed by the time a puppy finishes its vaccination course. Puppies can still go out safely before then if owners take precautions: avoid unvaccinated dogs and groups of unknown dogs, such as at dog parks, and choose puppy classes where all the puppies are vaccinated. Short trips to meet calm, vaccinated dogs and friendly people of different ages, and to hear traffic, bicycles and street noise, do more at this age than long walks.

How much walking different dogs need

Exercise needs follow what a breed was developed to do more closely than its size. A working sheepdog needs far more than a companion toy breed, whatever their relative size. The Kennel Club's breed profiles give a daily exercise band for each breed; the examples below are taken from those profiles. They cover all exercise, including play and off-leash running, not just time on a leash.

Individual dogs vary within a breed. Age, fitness, weight and health all change the right amount, and the Kennel Club profile for each breed is a sensible starting point before adjusting to the dog in front of you. A mixed-breed dog can be judged by its build and by how it behaves after a walk.

Adjusting walks through life

Puppies. The popular rule of five minutes of walking per month of age, twice a day, is a cautious guideline rather than a finding from research. Evidence on exercise and joint development is limited. A Norwegian study that followed about 500 puppies of four large breeds found that off-leash exercise in the first three months was linked to a lower risk of hip dysplasia, while walking on stairs over the same period was linked to a higher one. The authors suggested outdoor exercise on soft, moderately rough ground and no access to stairs for puppies up to three months old. Beyond that study, a practical and cautious routine for growing large-breed puppies is free play that lets them stop when tired, rather than long, forced walks at a steady pace.

Adult dogs. This is when most dogs have the most stamina. Varying the route adds new smells and ground surfaces, and a mix of leash walking, off-leash running where safe, and play covers both fitness and mental work.

Older dogs. Keep walking daily but shorten the distance and slow the pace. Several shorter walks are often easier than one long one. Limping, stiffness after rest, lagging behind or refusing to go on are signs of pain rather than laziness, and arthritis in older dogs is treatable, so these changes are worth a vet visit.

Signs a dog needs more or less exercise

An under-exercised dog is often restless, gains weight, greets people with frantic energy and struggles to settle at night. These are clues, not a diagnosis, since the same behaviors have other causes.

Too much exercise shows differently. The dog lags behind, lies down during play, is stiff after resting, pants hard in mild weather, or develops sore or worn pads. Exercise also carries a heat risk that many owners underestimate. An analysis of UK veterinary records found that exercise was the trigger in 74 percent of heatstroke cases where a trigger was recorded, against 5 percent for hot cars, and in the UK exertional heatstroke killed more dogs than confinement in a vehicle. Young male dogs were more likely to overheat during exercise, and flat-faced breeds such as Bulldogs, Pugs and French Bulldogs had higher odds of heatstroke from exercise, hot weather and hot cars alike. On warm days walk these dogs early or late, keep it short, and stop at the first sign of heavy panting or distress. A dog that collapses, staggers or vomits after exercise in heat needs cooling with water and urgent veterinary care.

Safety on walks

• Test the ground in hot weather. If pavement is too hot to hold the back of a hand on it for several seconds, it is too hot for paws. Use grass or shade, or walk at cooler times.
• Carry water on longer walks and in warm weather, and offer it during rest stops.
• Walk dogs that pull on well-fitted chest gear rather than a collar, so pressure falls on the chest instead of the neck.
• Make the dog visible in the dark with a reflective or lighted collar and leash.
• Check paws and coat after walks for cuts, grass seeds and ticks.

A dog that has not been walking regularly should build up gradually. Start with 10 to 15 minutes, add a few minutes every few days, and watch for stiffness the next morning. Dogs with heart or breathing problems, arthritis or obesity should have a plan agreed with their vet first.
