Being a pit bull owner, I have gone through what you felt with a lot of my family especially my mom, she is real uneasy around pit bulls. Ebony has really helped change her mind about them. Ebony paws at people like that all the time, thats a good thing, I'm sure she loved you. Next time you go back maybe someone can go with you to walk Robyn. Trust me once you get to know the breed you will feel less uneasy each time you are around them.
