Should you let your dog lick your face as vet warns of hidden health dangers
Scots owners may not mind a quick smooch with their dog but the consequences could be life-threatening
Dogs are called man's best friend for a reason, because for many people across the world, they are their owner's closest companion. Pooches share in the joy of special moments and provide comfort in the difficult ones.
To repay them for their love and loyalty, many owners may be partial to a smooch with their dog, or letting their cute canines lick their face when they greet them at the door or get excited after snack time.
However, letting your dog lick your face could come with a host of hidden dangers. Last week, it was revealed that a 26-year-old pregnant woman had developed a hydatid cyst caused by the tapeworm Echinococcus granulosus.
This was most likely transmitted through contact with dog faeces, according to the Daily Mail.
This has raised concerns about the common habit of allowing our furry friends to give us 'kisses'.
To set the record straight, Dr Aimee Warner, resident veterinarian at UK-based pet insurance company Waggel, has stepped in to explain why this intimate greeting might deserve a second thought.
"Whilst we all love to show affection with our pets, it's important to understand what might be transferred during those face licks," says Dr Warner.
"Dogs' mouths harbour numerous bacteria, including Capnocytophaga canimorsus, which can cause serious infections in humans in rare cases."
There were 15 reported cases of Capnocytophaga infections in England during the first quarter of 2023, making a total of 70 cases for the year. These figures are consistent with previous years, as per the UK Health Security Agency.
As a result, Dr Warner has highlighted three key facts pet owners should know.
Not everyone faces the same risk
People with weakened immune systems, the elderly, those without a spleen, and individuals with liver disease or who consume alcohol excessively face substantially higher risks from dog saliva exposure.
Infections can be life-threatening if untreated
When Capnocytophaga enters the bloodstream, it can cause sepsis, gangrene requiring amputation, kidney failure, and a heart attack. In severe cases, the mortality rate can reach 30 per cent, particularly in vulnerable populations.
Symptoms progress rapidly and require immediate attention
Initial signs appear within one to eight days and include blistering around wound sites, fever, vomiting, headache, and muscle pain.
Without prompt antibiotic treatment, the infection can quickly escalate to septic shock with dangerously low blood pressure, confusion, and organ failure.
Dr Warner offers these practical recommendations:
Redirect face licks to less sensitive areas like hands, which can be washed afterwards
Wash your face and hands thoroughly after close contact with pets
Keep pet vaccinations current and maintain regular dental check-ups for your dog
Consider scheduling biannual vet visits to monitor your pet's oral health
Seek immediate medical attention if you develop unusual symptoms after a dog lick
The last one is especially important if you have open wounds or are immunocompromised.
"The bond we share with our dogs is built on love, loyalty, and daily connection," Dr Warner added.
"We don't need to shy away from that closeness, but we do need to understand the health implications that come with it.
"With some awareness and simple hygiene, we can continue enjoying our pets' affection safely and confidently."
