My dogs are regularly bathed. "There ain't no bugs on them". I feel very safe and secure with them there. As far as bacteria in their mouths, yes they have a funky kind that you don't want introduced by a bite but humans and cats have worse bacterial bites than dogs. As far as their "kisses" go. Once my ex husband said "do you know where that dogs mouth has been?" I found out later that he was gay so I'm better off with the dog kisses. The dogs are much cleaner, kinder, absolutly non-deceptive, and will defend me to their death, won't steal my identity and take out loans in my name where my work started garnishing my wages until I got a lawyer, unlike my ex. I'll take a dog any day.
And person from Italy, I went to France on vacation and was in the Louvre with groups of Italian vacationers. Their BO was so bad I had to put a kleenex over my mouth and nose. BO is bacteria caused. My dogs smell wonderful. Baby shampoo.
