Too bad the same can’t be said for all the bacteria on the dog’s tongue.
Are dog mouths really cleaner than human mouths?
No. That’s a total myth.
Marty Becker, author of Chicken Soup for the Dog Owner’s Soul, puts it quite well when he says:
“All you have to do is look, watch, smell and you’ll realize that is not true.
They raid the garbage can. You know, we give each other a peck on the cheek when we say hello, they give each other a peck on the rear end.”
John Oxford, professor of virology and bacteriology at the Queen Mary University in London,expanded further on just how much bacteria your dog’s muzzle and mouth can carry.
“It is not just what is carried in saliva. Dogs spend half their life with their noses in nasty corners or hovering over dog droppings so their muzzles are full of bacteria, viruses and germs of all sorts.”
Those viruses and germs can cause conditions that can be damaging to human health, as one U.K. woman learned the hard way.
She contracted an infection from her Italian greyhound’s saliva. She didn’t even realize anything was wrong until she was on the phone with a relative and began to notice her speech slurring.
By the time the ambulance arrived, she was slumped in her chair, her health degrading rapidly. She recovered with two weeks of intensive care and plenty of antibiotics.
Blood tests showed the infection was due to capnocytophaga canimorsus bacteria, which is commonly found in the mouths of dogs and cats.
