(WAND) - A study has shown men's beards carry more microbes than dogs.

In the study at Switzerland's Hirslanden Clinic, swabs were taken from 18 men with hairy chins. They also were taken from 30 dogs of different breeds.

All of the beards tested were carrying "a significantly higher bacterial load." Only 23 of the 30 dogs had high counts.

Seven of the men were even carrying harmful microbes, the study found.
