Dream about black dogs biting my hands and bum.?

I had this dream last night about big black dogs (maybe wolves) biting my hands and bum while i was trying to get away and they kept following me. I wasnt running just walking and my hands were all red scratches from the bites. and a i girl i know colored in the scratches with blue felt tip pen. I know the girl she lives in my town but i dont really speek to her. i cant stop thinking about this dream it was really wierd, i usualy forget my dreams and i dont dream often but i have the feeling that this must meen something. help :)
