I own the most hyperactive pitbull known to man named Sissie. Therefore, I would feel comfortable with any breed or energy level of any dog. I am also athletic which allows me enough stamina to keep up with the dog will walking or playing. I once had a pitbull named Shug, before the one we own now, who was hit by a car in my cousin's care. This event prompts me to be very protective and vigilant with other's pets.
