dogs and cats have antibacterial mouths so kissing a dog is cleaner than kissing a human
I actually didn't know that.
Do you kiss your pets?
To my knowledge, a lot of animals have saliva with antibacterial qualities (that's why dogs
lick their wounds) but each kind of animal's natural bacteria is different and saliva of one
kind of animal can actually be harmful to another, because "good" bacteria is different for
different species. So you really shouldn't share saliva with another animal because it's
not necessarily hygienic at all. Not to mention most people don't clean their dogs' teeth
like they should, which does lead to bacterial build-up that's definitely not good to share.
