With several years of dog walking, fostering, caring for, and sitting under my belt, I've yet to meet a dog that is too difficult to too troublesome to handle. I am willing to uphold your own specific training and/or walking guidelines for your dog whether that is more strict of the leash, or more playful. Having walked all dogs from collies to pit bulls, I can handle any level of good behavior on a leash and I can hold my ground with strong pullers--even if there is a squirrel or rabbit in sight. Dog-walking is important for your dog, and with going to school, I enjoy a break from homework for quality dog time and fresh air. Really, think of it less as hiring someone to walk your dog and more like doing a pet-deprived and likely sleep-deprived student a favor.
