None.
that is one of the things that really puts me off about dogs. Just one of the things, I'm not a dog person at all.
I learned years ago never to trust someone who doesn't like dogs on at least some level.
That said...
No wet kisses though, that's absolutely disgusting.
I've never liked the licks either, but I accept it's an occupational hazard.
Also, while I'm happy to give them a pet I want to wash my hands straight away after.
It depends on the dog, if I know they are clean, then... Well.
I will wash my hands/face, etc when I am licked ASAP.
Unlike most, it has nothing to do with poo, it's just I was terrified of the whole CjD thing when I was a kid and there was a thing for a while about saliva and Tonsils and so on.
You never know what they have been eating, although I realise that dog food will be a lot more safer now and besides, my views are a but out - dated, not that I can shake them.
Ironically, I'll happily kiss another person and gawd only knows what they have been eating/licking, etc.
