A new dental study suggests dog owners shouldn’t go overboard with the puppy love.

The report in Archives for Oral Biology found that kissing your dog may lead to tooth decay and gum disease in both humans and canines. Researchers in Japan came to this conclusion late last year through a dental plaque analysis of dogs and owners who were more and less affectionate.

They found harmful human bacteria in the mouths of dogs who kissed their owners and dog germs in humans.
