A new study in the journal Archives of Oral Biology suggests that it's possible for disease-causing oral bacteria to be exchanged between dogs and their owners.
Japanese researchers examined dental plaque from 66 dogs, as well as dental plaque from 81 people from Japan who visited a dog-training school or animal clinic during 2011. They conducted analysis to find the presence of 11 disease-causing oral bacteria -- called "periodontopathic" species -- in the plaque.
