Exercise in Dogs: What It Really Means—and What It Doesn't

What does "exercise" mean for dogs?

For dogs, "mental and physical stimulation" refers to the sum of all physical, cognitive, and social activities that enable a dog to lead a species-appropriate life. Important: Mental and physical stimulation does not mean "tiring the dog out." A dog that is adequately stimulated is not exhausted, but rather in a state where its physical, mental, and emotional needs are met.

Engagement encompasses three dimensions: physical (exercise, walks, free-roaming), cognitive-mental (search games, learning, problem-solving, exploring), and social-emotional (interaction with the primary caregiver, encounters with other dogs, calm participation in family life). A professionally sound activity level is the opposite of mere busyness—it is the balance between appropriate activity and sufficient rest.

Background + Scientific Context

Scientific research on canine well-being has consistently shown for about 15 years that dogs need cognitive stimulation at least as much as they need physical stimulation. In a review article, Mehrkam and Wynne (2014) documented that enrichment activities—that is, activities that challenge the animal cognitively—sustainably lower stress levels and reduce stereotypical behavior.

Studies on sleep physiology in dogs (Kis et al. 2017, Bunford et al. 2018) show that adult dogs need 12–16 hours of sleep per day, while puppies and senior dogs need up to 20 hours. Chronic sleep deprivation leads to increased stress reactivity, impaired learning consolidation, and behavioral problems.

Research on frustration (McPeake et al. 2021) and chronic stress (Beerda et al. 1999) also shows that constant stimulation—such as excessive ball-throwing, jogging with a dog over long distances, or nonstop activity—leads to sympathetic dominance. The dog appears "tired," but the stress hormone system continues to be active. Result: Dogs that can’t settle down.

Vitomalia-Position

Our position is clear: more activity is not the solution. Dogs that seem restless, reactive, or “hyperactive” usually don’t need more exercise—they need to be better able to relax, clearer routines, and a stronger bond. The most common recommendation in our behavioral analyses is this: fewer hours of activity, but more quiet bonding time, more sniffing walks, and more active breaks.

We firmly reject the "exercise race"—the idea that a good owner must play with their dog for hours every day. That puts too much strain on both of them. Needs-based exercise is tailored to the individual, not standardized.

When does capacity utilization become a factor?

The Specific Situation:

Puppies and young dogs: Growth and learning require age-appropriate, short sessions and plenty of sleep
Working Pet Owners: Planning Capacity in a Compact, High-Quality, and Realistic Way
Reactive Dogs: Rethinking Exercise – See Reactivity
Seniors: Stay mentally active, adapt physically
Working breeds (Border Collie, Malinois, Husky): A very clear structure rather than more action

Practical application

Sleep first: Before you think about increasing his activity level, check: Is your dog getting 12–16 hours of sleep? Does he have quiet places where he can retreat?
Rest-to-activity ratio of 80/20: 80% relaxation, mindfulness, and breaks; 20% active engagement. This applies to most family dogs.
Sniffing instead of sprinting: A 30-minute sniffing walk is more cognitively stimulating than 60 minutes of jogging.
Prioritize mental stimulation: search games, trick training, food-based games. 10–15 minutes of cognitive activity often replaces 30 minutes of physical activity.
Understanding bonding as engagement: Spending time together, lying close, quiet attention—this isn’t “non-engagement”; it’s the foundation.
Adjust accordingly: Watch your dog. Does he settle down after the walk? Does he fall asleep? Or is he still running around? The latter means too much activity and not enough clarity.

Common Mistakes & Myths

"A tired dog is a good dog." Overtiredness leads to irritability, poor impulse control, and chronic stress.
"Border Collies need four hours of activity a day." Wrong. They need clear tasks and owners who set an example of calmness.
"Throwing a ball is a good way to keep them active." Repeated fetching without breaks leads to tunnel excitement and a pleasant state of constant arousal.
"My dog doesn't get enough exercise in the city." The city offers plenty of stimulation. The problem is usually sensory overload, not a lack of activity.
"My dog has ADHD." Hyperactivity in dogs is usually a sign of stress or lack of sleep—rarely a neurobiological disorder.

State of the art in 2026

The body of research on enrichment is robust (Mehrkam & Wynne 2014). Research on sleep in dogs has increased (Kis et al. 2017). Initial evidence suggests that quantity is not a good indicator of adequate exercise—quality and the owner-dog relationship are more relevant. The frequently cited “4-hour” recommendations for working breeds are neither empirically supported nor unproblematic from an animal welfare perspective.

Frequently Asked Questions

How much exercise does my dog need every day?

There is no one-size-fits-all answer. A general rule of thumb: 1–2 walks that include time for sniffing, 10–20 minutes of mental stimulation, plus 80% relaxed interaction. Adjust according to age, breed, and how the dog is feeling that day.

My dog can't seem to settle down—is he not getting enough exercise?

Often the opposite is true. Check for: too little sleep, too many stimuli, too much activity. Try scaling back for a week—the dog will often become calmer.

Which is better: physical or mental exercise?

Both. Mental exercise is more efficient: 15 minutes of a search game can be more exhausting than a 45-minute run. Physical exercise remains essential for joints and metabolism.

My dog is a Border Collie—does he need a job?

Yes, but "work" doesn't mean "action." Training, tricks, and cooperative games. Calmness and bonding are just as much a part of the job.
