I have heard numerous times that you shouldn't let a dog lick you because their mouths are dirty, they lick their butt, etc.
Stephen was told by someone (I think it was his dad because he won't tell me who told him and he knows how I feel about some of the stupid stuff that comes out of his dads mouth about the dogs) that if you let a dog lick you, you will get salmonella and rabies.
When he told me that, I about peed myself laughing. I explained to him that if we still fed RAW, that no, I wouldn't want to be licked for 15-20 minutes after they ate. As far as rabies...you have to be kidding me!
For awhile Stephen wouldn't let the dogs lick him which is another reason why I think his dad told him this, he would have no reason to listen to anyone else. After a few days he got over it and then would jokingly tell our friends that just to get me started. Now he lets them lick his face, he kisses them, they share food, etc.
His family isn't very animal friendly so I can see his dad saying something stupid and him believing it because it was his dad that said it. I about have him to the point that he takes whatever his dad says about the dogs with a grain of salt.
