Is it safer to french kiss a dog or a human?

[silverwolf1]

I honestly don't know.
I have frenched my fair share of humans, and enjoyed french kissing a few dogs, and I've never gotten sick from either. I THINK, and this is only an opinion, that as long as good dental and oral hygiene is observed by both parties (I always brushed my dogs teeth, etc.) there is little danger from either species.
