Canine Kiss Bacteria May Be Harmful
Those sloppy wet kisses from your dog could be harming you both.
A Japanese study found dog owners and their pets swap oral bacteria that causes gum disease and tooth decay. When researchers analyzed dental plaque in over 50 dogs and their owners, they found human bacteria in the mouths of dogs. Bacteria was most prevalent in older dogs and those sharing high contact relationships with their owners.
Canine bacteria was also detected in the mouths of humans, including several with low contact relationships.
