I am not intimated by large or aggressive dogs. I have owned Rotts and Shepherds. I have also sat for a pitbull/boxer on a number of occasion. She really didn't want to go home! I enjoy the larger breeds. Usually even standoffish dogs or slightly aggressive dogs warm up to me after a bit. I have a large property but a small yard so it's easy for either a playtime in the yard or a nice walk through the woods are available. I don't live on a busy street so walks around the neighborhood is available also. Your dog will be given plenty of attention and affection. I live in a small town out in the country. Hopefully this gives you an idea of my qualifications.
