Dog yelps when touched?

My 1 year old queensland yelps whenever I touch her. Sometimes, when I have her in my hands, she'll scream as if im trying to kill her. She in fact acts like a dog with rabies because of her insane behavior. Mandy (dog) is up to date on her shots, no heath problems. She plays with my rather rough dogs fine. However, as soon as I get close to her, simply trying to pet her, she goes into a fit and screams. Whats wrong?
