You could get pimples because the tongue of a dog is very dirty.
They regularly lick their genitals clean, most dogs eat everything on the floor etc.
That’s why you always have to get a syringe with a dog bite, chance of illness.
So there is a lot of mess in the saliva, if your skin is sensitive to it, it can get clogged and you may get pimples.
Rather not let your face lick so, or at least clean your face after that time. Can just with such a cleaning cloth, look like baby wipes.
In a somewhat older article on Volkskrant.nl I found this :
A dog’s tongue is a doctor’s tongue, the French say. Is that right? Ellen de Visser examines it in her weekly health section in de Volkskrant.
Dogs lick their fellows as a sign of submission and the boss, as chief, also regularly gets a swipe from a dog’s tongue. Half of the one and a half million dog owners think that is not a problem, according to Dutch research. In fact, medicinal properties are sometimes attributed to the saliva of the dog. Langue de chien, langue de médecin, says the
French proverb: a dog’s tongue is a doctor’s tongue. Is that right ?
A dog licks on anything and everything, says microbiologist Paul Overgaauw (University of Utrecht) and therefore the tongue of the animal is definitely not a doctor, but above all a potential pathogen. He suspects that the misunderstanding arises because the characteristics of humans and animals are combined with each other. If a dog licks a wound cleanly by itself, it heals faster because the circulation is stimulated and the dirt disappears. It has also been shown that there are substances in the saliva of people that promote the wound recovery. For example, the idea may arise that you can have a wound swallowed by the dog, says Overgaauw.
But dog saliva can kill at most specific dog bacteria. And that does not matter to a person. On the contrary: the mouth flora of dogs contains many bacteria that can be dangerous to humans.
For example, a study by the Utrecht Faculty of Veterinary Medicine last year showed that one-fifth of the dogs have the venomous bacterium C. canimorsus in the oral cavity. It can cause serious infections in people, to blood poisoning. He does not want to overdo exaggerate, but especially the elderly, children and people with a weak immune system, says Overgaauw.
Last year, the American health service CDC drew up a long list of known contamination cases. Not a pleasant reading material for the breakfast table: a 60-year-old man with chronic eczema who dies of kidney failure and blood poisoning after the dog has sickened the sores on his legs; a 67-year-old man who regularly has his chronically inflamed ear licked by his dog and therefore has a meningitis; a 48-year-old diabetic patient who is infected with the resistant mrsa bacteria because the dog sleeps in bed with him and regularly licks his face.
