Why does my dog run away and pee when my friend comes near her? Shes fine with everyone else.
She's scared. She may not know that person so well. My dog does that when my mother tries to pick her up.
Fear. Peeing is a submissive behavior, which is why it's bad to scold for peeing submissively... she'll just do it more. Ask your friend to sit in the floor and socialize with your dog for a while.
she probably has another dog
