5. Licking your wounds
In the ancient world, wise folk and healers noticed that dogs licked their own wounds as well as those of people.
Wounds, both on the surface and beneath, seem to draw the attention of dog tongues. From the ancient civilizations of Egypt, Greece, and Rome all the way through to the Middle Ages in Europe, you might be surprised to learn that dogs were not only encouraged, but even trained to lick wounds as a mode of healing.
Fortunately, these days, we have topical antibiotics, but it is still common for a minor injury during a walk to receive a dog’s attention.
