Men’s beards are dirtier than dogs’ fur, study says
The Hirslanden Clinic looked at the “bacterial load in colony-forming units (CFU) of human-pathogenic microorganisms” in swabs taken from 18 men’s beards and 30 dogs’ necks. All of the guys with beards had high microbial counts, but only 23 of the 30 dogs had the same high count.
