Vet-Approved Guide: Why Dogs Lick Human Wounds & What It Means 2025 🐶🐾

By Dr. Duncan Houston BVSc

It's a familiar scene for many dog owners: you sustain a minor cut or scrape, and your canine companion promptly attempts to lick the wound. While this behavior might seem endearing or even helpful, it's essential to understand the motivations behind it and the potential implications for both you and your pet. Let's delve into the veterinarian-approved reasons why dogs lick human wounds and why it's advisable to gently discourage this behavior. 🛡️

🔍 Understanding the Behavior: Why Do Dogs Lick Human Wounds?

1. Instinctual Healing Behavior

Dogs, like many mammals, have an instinct to lick wounds. This behavior is rooted in their evolutionary history, where licking served to clean wounds and promote healing. When your dog licks your wound, they're extending this instinctual care to you, whom they consider part of their pack.

2. Affection and Empathy

Licking is also a sign of affection and empathy. Dogs often lick their owners to show love and concern. When they notice you're injured, licking the wound can be their way of comforting you.

3. Attraction to the Taste

Human wounds can have a salty taste due to sweat and blood, which some dogs find appealing. This sensory attraction can prompt them to lick the area.

⚠️ Potential Risks: Why You Should Discourage This Behavior

While the intentions behind the behavior are benign, allowing your dog to lick your wounds can pose health risks:

• Infection Risk: Dog saliva contains bacteria that can lead to infections if introduced into open wounds.
• Delayed Healing: The mechanical action of licking can reopen wounds or cause further irritation, delaying the healing process.
• Transmission of Diseases: In rare cases, bacteria from a dog's mouth can cause severe infections in humans, especially those with compromised immune systems.

🛠️ How to Gently Discourage Wound Licking

To protect both yourself and your dog, consider the following strategies:

• Cover Wounds: Use appropriate bandages to prevent access to the wound.
• Redirect Attention: Offer toys or treats to distract your dog when they attempt to lick your wound.
• Positive Reinforcement: Reward your dog for refraining from licking behavior.
• Training: Teach commands like "leave it" to deter unwanted licking.
