Do you remember Lucy from the comic strip Peanuts?
True or False:
Is a dog's mouth really cleaner than a human's mouth?
While it is true that dog bites are less likely to transmit a communicable disease to a human, they are still quite capable of causing an infection.
Dogs' mouths are filled with all kinds of bacteria, depending of course upon what the dog recently had in its mouth. When you consider that dogs use their mouths much like people use their hands, the bacteria counts in their mouths can be quite high.
Next, imagine that after sampling the world with his tongue, your dog comes back inside only to smear his saliva and bacteria-filled kisses all over your hands and face.
While canine kisses can be sweet, you really should consider thoroughly washing your hands and face afterward.
