I agree to a point, but a lot of dogs don't get proper dental care, eat poop and lick buttholes-- sorry, but I don't want any of that on my face, I don't care how magical their saliva is supposed to be.
Not to mention I find dog slobber to be extremely off-putting for reasons other than germs. Just like I would find it extremely off-putting if someone went up to me with a clean wet washcloth and started rubbing it on me.
