Why Does My Dog Lick My Wounds?
Is it sweet? Gross? Helpful? Harmful? Let’s find out why your four-pawed pal is so keen to help—and most importantly, whether you should let them.
Why Does My Dog Lick My Wounds?
To Help Them Heal
Back in Ancient Egyptian times, doctors believed in the healing powers of dog saliva and even used it to treat wounds. While modern medicine has come a long way since then, there is some science behind the idea—saliva contains proteins that can help fight infection and encourage wounds to heal faster. So, just like how kids suck on a scraped finger, wound licking in dogs is an instinctive action to try and “fix” you.
To Remove Dirt and Debris
Our furry friends naturally like to keep things clean—which is why the cone of shame is often needed to stop your dog from licking their own wounds. Along with the potential healing properties of their saliva, their tongues can clear away dirt, debris, or anything else that doesn’t belong.
To Soothe You
Licking is a sign of love and comfort that pups learn from their fur moms. Whether you’re hurt or just feeling down, their instinct is to make you feel better by licking you. Plus, it makes them feel good too—releasing serotonin into their brain and giving them all the happy feels.
Is It Good for Dogs to Lick Your Wounds?
The Good
People often ask, “Isn’t dog saliva healing?” It’s true: research shows that saliva—both human and canine—contains proteins that can help heal wounds and fight off infections. Plus, the nitrite in saliva converts to nitric oxide when it comes into contact with your skin, offering an extra layer of protection against infection. Gentle licking can also remove dirt and debris from wounds, helping to keep them clean and potentially preventing further irritation.
The Bad
As helpful as it might sound, letting your dog lick a wound isn’t always a great idea. First, overzealous licking can delay healing by damaging the skin, reopening wounds, or dissolving stitches—making things worse instead of better.
Most importantly, our furry friends’ mouths are full of bacteria. While some are harmless, others can cause serious infections if introduced into an open wound. For example, Pasteurella—a common bacterium found in dogs’ mouths—can thrive in human tissue and potentially cause life-threatening infections.
In fact, there have been documented cases where dog licks caused serious complications: one woman lost fingers after her pup licked a small burn, and a man developed a kidney infection from bacteria introduced through a hand wound. In rare cases, meningitis has even been traced back to dog saliva.
How to Discourage Your Dog from Licking Your Wounds
Now that you know it’s not the best idea to let your dog lick your wounds, here’s how to gently redirect that loving instinct:
- Cover your injuries: Clean the wound thoroughly and keep it covered with a sterile bandage to protect it from your pup’s tongue.
- Redirect their affection: Train your furry friend to show love in safer ways—like snuggling, offering a paw, or settling quietly beside you.
- Avoid encouragement: Don’t praise or reward licking behavior—even if it’s cute, it’s not worth the health risk.
While your dog’s intentions are pure, letting them lick your wounds isn’t the healthiest choice. A good bandage, some TLC, and lots of pets (sans tongue) is the way to go!
