Thirty minutes to two hours

Guides that round up veterinary advice land in the same range: most adult dogs need somewhere between 30 minutes and 2 hours of activity a day, split into one or two walks. Where a dog falls in that range is about breed and temperament, not size. A bulldog or a shih tzu is content with 30 to 45 minutes. A border collie or a young labrador treats an hour as a warm-up.

Age moves the number more than anything. Puppies have soft, growing joints and shouldn’t be marched. A common rule of thumb is five minutes of walking per month of age, up to twice a day, so a four-month-old gets 20-minute outings, not hikes. Old dogs go the other way: a gentle hour at their pace, on soft ground where you can find it, beats a fast half hour on concrete.

A dog with a heart condition, bad hips or a breathing problem has different needs. Ask the vet who knows your dog to set the right activity level. The ranges above are a starting point.

A loose leash and a nose down is a dog doing what the walk is for.

Walks are for sniffing

People measure walks in minutes and miles. Dogs measure them in smells. A dog that gets to stop, sniff and read the news on every tree comes home more settled than one hurried round the block at your pace, because the sniffing is the work. Trainers call it a decompression walk, and it’s the easiest tool there is for an anxious or overexcited dog.

So split the walk. Keep a brisk stretch for the exercise, then let the dog set the pace and the route for the rest. Bring water on anything over half an hour in summer. That way you come home with a dog that’s tired in the head as well as the legs.

Denver’s leash rule

In Denver the leash isn’t optional. Dogs must be on a leash everywhere in public, parks included; the only exception is inside a fenced off-leash dog park. Park rangers and Denver Animal Protection both write tickets, and off-leash dogs have become the top complaint in city parks. Citations climbed from 167 in 2022 to over 900 two years later.

The fine is the smaller risk. An off-leash dog that gets into a fight, knocks someone down or runs into traffic leaves its owner on the wrong side of the law for whatever happens next. A long line in an open field is a legal way to give a dog room. A dropped leash isn’t.

Hot pavement, thin air

Denver sits a mile up and the sun is stronger than the temperature suggests. On a summer afternoon, asphalt gets hot enough to burn pads. Press the back of your hand to the pavement for seven seconds. If you can’t hold it, the dog can’t walk on it. Go early, go late, or walk on grass and dirt.

Dry air pulls water out of a panting dog fast. Bring water on every warm walk.

Winter has its own hazards. Ice melt on sidewalks stings paws and is bad to lick off; rinse feet after a walk on a treated street, or use boots. On the coldest days a short walk and a game indoors beats a long march for a small or short-haired dog.

A walk that counts

  1. Leash on before the door opens. A standard 6-foot lead in the city; a long line only in open space.
  2. Ten minutes brisk, then let the dog lead. Sniffing time isn’t wasted time.
  3. Water in summer, a towel by the door in winter. Check the paws when you get back.
  4. The same route is fine. Dogs like knowing the neighborhood. Change it once a week for the novelty.
  5. Pick up after the dog, every time. Denver parks have the bags; the fine for not using them is real.

The right length is the one that leaves the dog relaxed on the floor an hour later. Start at 30 minutes, watch the dog, and adjust.
