How much exercise does a dog need? By breed and age

Updated July 27, 2026 · reading time approx. 6 min

"It depends" is the honest answer, but not a very useful one on its own. A basset hound and a border collie can weigh about the same and still need wildly different amounts of exercise. Let's break down how much movement a dog actually needs — by size, breed, and age — and how to tell if it's getting too little or too much.

The general rule everything else builds on

Most healthy adult dogs need 30 minutes to 2 hours of active exercise a day, split across two or three walks. That's a wide range on purpose: it depends on the breed's original purpose (working dog vs. companion), age, and current health. Treat the number as a starting point, not a universal prescription.

By size and breed

• Low-energy small breeds (pug, French bulldog, chihuahua, bichon frisé): 20–40 minutes a day, split into shorter walks. Flat-faced (brachycephalic) breeds also need a much slower pace in heat and humidity.
• Moderate-energy medium breeds (cocker spaniel, beagle, dachshund): 45–60 minutes, ideally including some off-leash time if the environment allows it.
• High-energy and working breeds (border collie, German shepherd, Siberian husky, Jack Russell terrier): 1.5–2+ hours, often paired with mental stimulation (fetch, scent work, obedience training). Without it, that energy tends to spill over into barking or destructive behavior at home.

Breed tells you a lot, but not everything — the individual dog always matters too. Compare temperament and exercise needs across breeds in our breed guide.

By age

Puppies have energy to spare, but their bones and joint cartilage are still developing, so too much exercise can actually cause harm. A widely used guideline: 5 minutes of exercise per month of age, twice a day, until the dog reaches adulthood (around 12 months for small breeds, 18–24 months for large ones). A six-month-old puppy should get roughly 30 minutes of controlled activity per walk — not an hour-long run.

Adult dogs follow the breed guidelines above. For senior dogs (usually from age 7–8, earlier for large breeds), don't stop exercise — adjust it: shorter, more frequent walks, a slower pace, softer ground. Some stiffness after resting is normal in older dogs; sudden limping or reluctance to walk is a reason to see a vet.

Signs of too little exercise — or too much

A dog that isn't getting enough exercise usually shows it in behavior before it shows on the scale: more barking, chewed-up furniture, restlessness, nudging you with a toy at ten at night. Weight gain follows soon after, which puts even more strain on the joints.

Too much exercise looks different: heavy panting well after resting, reluctance to get up for another walk, limping, or sensitivity when you touch the paws or joints. Either sign means it's time to adjust the routine, not push through it.

The bottom line: exercise is individual, not universal

There's no single number that fits every collar — only a combination of breed, age, and current health. Before you get a dog, check how much exercise the specific breed actually needs and compare it honestly with how much time you can give every single day, including in the rain in January.
