How can i convince my dog that its not ok to pee on people?

My dog's name is Charlot and she never listens to what i am saying.I told her not to ruin the furniture and she ignores me and keeps tearing it up. She keeps peeing on my daughter Sandra and my baby son Jordan . She peed on me 2 times today and the funny thing is she runs off like shes doing it on purpose. I tried alot of methods but it didn't work. I am thinking of getting her trained by a professional. We had this dog for at least 3 years and she just started doing this about a month ago.Please help.
