Dogs Have Less Germs Than Bearded Men A research team in Switzerland recently measured bacteria from the facial hair of 18 men. They then compared it to samples taken from the necks of 30 canines. In their findings, the team at Hirslanden Clinic said that the human group had more germs than 23 of the dogs.
