Why do Dogs Lick Their Wounds?

Why do dogs lick their wounds? Why do we instinctively rub an injury? And what the heck does this have to do with Quality of Life?

When a dog licks a wound, it’s not just a habit—there’s purpose behind it: they warm the area, clean it with natural enzymes, and promote blood flow.

Now think about when a person gets hit—say, with a ball to the arm. After shouting “ouch,” they usually start rubbing the spot. It’s not random. That touch increases blood flow, and blood is our body’s delivery system for oxygen, sugar, nutrients, and vitamins. Increased circulation means faster recovery from intense workouts or injuries, better detoxification through the kidneys, and more energy delivered to tired muscles.

Better blood flow = You feeling better. And the best part? You can improve it actively, passively, or even without moving.

1. Active Blood Flow – Move to Feel Better

Any movement gets your blood pumping: stand up and sit down from the couch 10 times, do 100 bridges and 100 crunches first thing in the morning, go for a walk, play tennis—whatever gets you moving.

Movement signals your body to adapt. Your heart begins to pump more fully and forcefully. Over time, your circulation improves, new capillaries form, and your energy increases—even while doing simple daily tasks.

Stretching and cardio are two other great options. They not only increase circulation but also improve heart health, flexibility, and recovery.

2. Passive Blood Flow – Intense Training, Bigger Payoff

Passive blood flow boosters are things like HIIT workouts or lifting to failure. These cause controlled muscle damage or depletion, prompting your body to increase circulation to repair and refuel for the next 24-48 hours.

Examples:

  • HIIT sprints: 20 seconds of work every 2.5 minutes, 8 rounds
  • Resistance training: 3-5 sets of 12-15 reps with short rest between sets

This style of training elevates your heart rate and creates a long-lasting demand for nutrients and recovery.

3. Really Passive Blood Flow – No Sweat Required

Think massage, sauna, or cold plunge. Rubbing an injury (like your elbow after bumping it) helps stimulate warmth and blood flow. Saunas increase circulation through heat, while cold plunges force your body to warm itself, boosting blood flow once you’re done and the body starts to shiver.

Even using a massage gun can promote recovery and circulation—just remember to hydrate extra afterward, as blood will carry out waste products that need to be flushed.

Wrap-Up

These three methods—active, passive, and really passive—can all boost blood flow, which improves energy, mood, recovery, and efficiency. All of that = a better quality of life.

Yes, inspiration really can come from anywhere… even your dog licking her paw after a long hike.
