dog's personal space

How can I stop my dog from puting her face into mine. I've hear of people getting into a dogs personal space, but never the other way around.

This is pack behavior. You're part of his pack, pack members nose each other & lick faces & groom, so that's what he does.
   
The best thing to do is to accept some grooming & then gently fend him away & scratch his ears. Make it a daily ritual.
   
He loves you & trusts you, that's why he's so willing to get so close.

After I love on her she won't go away. She just want's to get closer and closer.
