Yes, letting your dog lick your face might not be as harmless as it seems. A study has highlighted potential health risks associated with this behavior, mainly due to bacteria and parasites that dogs can carry in their mouths.
Additionally, dogs often lick various unsanitary surfaces, including their own fur, paws, and even fecal matter, which can introduce more bacteria into their mouths. Some experts suggest washing your face if your dog licks you and avoiding direct contact, especially around the mouth, eyes, and open wounds.
Why It Can Be Risky
-
Harmful Bacteria
Dogs’ mouths contain bacteria like Capnocytophaga canimorsus, which, though rare, can cause severe infections in humans—especially those with weakened immune systems. Other bacteria like E. coli and Salmonella can also be present. -
Parasites
Dogs may carry parasites like Giardia and roundworms, which can transfer through licking and cause gastrointestinal illnesses in humans. -
Zoonotic Diseases
Some diseases can spread between animals and humans, such as MRSA (Methicillin-resistant Staphylococcus aureus) and Pasteurella, which can lead to infections. -
Open Wounds & Mucous Membranes
If a dog licks an open wound or the eyes, nose, or mouth, bacteria have an easier entry point into the body, increasing the risk of infection.
Who’s Most at Risk?
- Infants and young children
- Elderly individuals
- People with weakened immune systems (e.g., those undergoing chemotherapy or with chronic illnesses)
How to Stay Safe
- Avoid letting dogs lick your face, especially near the mouth, eyes, or open cuts.
- Wash your hands and face after playing with or petting your dog.
- Keep up with your pet’s vaccinations and deworming.
- Maintain good oral hygiene for your dog to reduce bacterial risks.
While many pet owners love their dog’s affectionate licks, it’s good to be mindful of the potential health risks. Would you reconsider letting your dog lick your face after learning this?
