The Walk Prescription: Daily Stress Relief for You and Your Dog

This article is by our summer intern Chae Hyun Lee.

For humans, daily walks lower cortisol, release mood-boosting endorphins, and help regulate emotions. For dogs, the benefits are strikingly similar, with the added bonus of essential mental stimulation that helps prevent anxiety-driven behaviours like destructive chewing and barking. This mutual benefit is part of the broader human-animal bond: a connection that research shows can reduce stress and improve wellbeing for both species through physiological changes like decreased cortisol and increased Oxytocin.

How Walks Lower Cortisol

Cortisol often gets a bad reputation, but this “stress hormone” serves important functions; gives us energy, fuels metabolism, reduces inflammation, supports blood pressure, and regulates sleep. The problem arises when chronic stress keeps cortisol levels elevated, which can harm physical and mental health.

Exercise is perceived as a physical stress to both human and dog bodies, causing an initial spike in cortisol for energy, but ultimately leaving baseline cortisol levels lower post-workout. Moreover, research shows that regular exercise can lower baseline cortisol levels over time.

Fascinatingly, dogs can sense a reduction in their owner’s stress through olfactory and behavioural cues, and in turn experience a parallel reduction in their own stress levels. Thus, walks function as a co-regulatory activity, lowering stress for both of you at the same time.

Strengthening Your Bond, One Walk at a Time

Oxytocin, also known as the “love hormone,” is released by the pituitary gland and helps relieve stress and improve mood. It is associated with social bonding, trust, and empathy. Exercise triggers the release of this “feel-good” hormone by activating the brain’s hypothalamus, which signals the pituitary gland to secrete oxytocin into the bloodstream. When you walk with your dog, interactions like petting and eye contact boost oxytocin even further.

The Power of Routine 

More importantly, the predictability of walks matters. Although dogs cannot read clocks, they have a clever and accurate internal clock. Dogs that are walked at consistent times each day feel more in control over their environment and are therefore less anxious than dogs walked at unpredictable times

Walks as Mental Enrichment: A World of Scents 

Beyond physical exercise, walks are also an enrichment exercise for your dog. Exposure to different scents, sights, and textures provides much-needed mental stimulation for a dog that spends most of its day indoors. This can help reduce your dog’s baseline stress and reduce boredom. 

Finding the Right Balance

For most dogs, 30 to 90 minutes of daily moderate exercise is enough physical activity and mental stimulation to tire them out without exhaustion. It’s ideal to have a balance of physical movement and mental enrichment - this could look like a walk or jog combined with playtime. The key is not to over-exhaust your dog, as this can elevate cortisol levels instead. For senior dogs, we recommend more frequent, shorter walks with daily consistency. 

A Local Note: Navigating Hong Kong's Slippery Surfaces

In Hong Kong, many pets walk in urban environments including shopping malls or apartment buildings, where marble floors are common and slippery surfaces can make walks hazardous. For senior and injured dogs, slipping and falling is especially dangerous and can lead to serious injuries. Slippery surfaces can also reduce a dog’s confidence, and some may become reluctant to continue walking. When this happens, Dr. Buzby’s Toe Grips can be a supportive solution.

Daily walks are a small but powerful tool for keeping you and your pooch mentally and physically healthy. So, grab that leash, step outside, and take that walk prescription!
