Is my dog being resource protective or?

Hi, so I’ve had a nagging question, so let me explain first, my mom was a dog breeder and after my nine year old crested was abandoned (not being feed or anything) by her birth mom I raised from birth fed her, cared for her, loved her like she was my own. She grew up around me being abused verbally and physically, now when ever someone goes to touch me too quickly she goes after their hand. Everywhere I looked people say it’s resource protection so does she really see me as a resource to guard? Or is she actually protecting me because she views me as a friend/mom?
