Exercise is one of the most important things you can do for your dog’s physical and mental health — and one of the most commonly misjudged. Too little causes obesity, behavioral problems, and restlessness. Too much causes joint damage, especially in puppies whose growth plates are still developing. Finding the right balance requires knowing your specific dog.
Exercise Needs by Breed Group
Working, sporting, and herding breeds (Border Collie, Australian Shepherd, Siberian Husky, Labrador Retriever, German Shepherd, Vizsla, Weimaraner): 90 minutes to 2+ hours per day. These breeds were developed for demanding all-day physical work. Without adequate exercise, they will find their own outlets — usually ones you won’t appreciate.
Hound breeds (Beagle, Basset Hound, Greyhound, Bloodhound): highly variable. Scent hounds like Beagles need a good hour of activity daily and should always be leashed or in a secure area — their nose overrides their recall. Greyhounds are famously sprinters, not endurance runners: 30–40 minutes including a short off-leash sprint is often enough.
Terrier breeds (Jack Russell Terrier, Scottish Terrier, Bull Terrier, Airedale): most terriers are high-energy for their size and need 60–90 minutes of activity, ideally with opportunities to dig or use their nose.
Toy breeds (Chihuahua, Maltese, Toy Poodle, Pomeranian, Shih Tzu): 20–30 minutes of moderate daily activity. Do not be fooled into thinking small dogs don’t need exercise — they do, but proportionally less and with lower-impact activities.
Brachycephalic (flat-faced) breeds (French Bulldog, English Bulldog, Pug, Boston Terrier): require careful exercise management. Their narrowed airways make them overheat quickly and struggle to regulate breathing during exertion. Avoid exercise in hot or humid conditions, keep sessions short (15–20 minutes), stop at the first sign of heavy panting or distress.
How Age Changes Exercise Needs
Puppies: Less is more — and this surprises many owners. Puppies’ growth plates (the soft cartilage at the ends of bones) do not fully ossify until 12–18 months depending on breed, and longer in large breeds. Repeated high-impact exercise before growth plates close can cause permanent joint damage. The common guideline: 5 minutes of exercise per month of age, up to twice daily. A 4-month-old puppy needs about 20 minutes, not a two-mile run. Free play in a safe yard counts.
Adults (1–7 years): This is peak exercise age. Work up to the full recommendation for the breed and maintain it consistently. Regular exercise at this stage builds the muscle mass and joint health that will carry them into senior years.
Senior dogs (7+ years, or 5+ for giant breeds): Reduce intensity, not necessarily duration. Shorter, more frequent walks are easier on aging joints than one long outing. Avoid hard surfaces like concrete when possible — grass and dirt are gentler. Swimming is excellent for senior dogs with arthritis. Watch for signs of fatigue (slowing down mid-walk, reluctance to continue) and reduce accordingly.
Signs Your Dog Needs More Exercise
If you are seeing these behaviors, insufficient exercise is a likely contributor:
- Destructive chewing, especially when unsupervised
- Excessive barking or whining
- Hyperactivity indoors, difficulty settling
- Jumping, nipping, or rough play that escalates quickly
- Weight gain without dietary changes
- Pacing, circling, or repetitive behaviors
Signs You Are Over-Exercising Your Dog
Over-exercise is real, especially in puppies and senior dogs. Warning signs include:
- Lameness or reluctance to exercise after rest
- Sore, worn, or raw paw pads
- Excessive panting that doesn’t resolve within 10 minutes of stopping
- Stiffness the morning after a long outing
- Lying down mid-walk and refusing to continue
Mental Exercise Counts — And Often Counts More
Physical exercise is not the only kind that matters. Mental exercise — problem-solving, nose work, learning new commands, puzzle feeders — is surprisingly tiring for dogs. A 15-minute training session or a 20-minute scatter feeding game in the yard can have the calming effect of a much longer walk. This is especially useful on days when weather or schedule prevents a full outing, and for dogs whose joints cannot handle intense physical activity.
