I grew up taking care of dogs. I've had a boxer for the past 3 years with tons of energy. I use a power wheelchair that goes about nine miles an hour and we go for miles with him running the whole way. It's kept him in great shape and he loves it. I just hook the leash on the back of the chair and go! He'd never be able to get away no matter how hard he pulls. I'm one of those obnoxious dog parents and could send you pictures all day long if you wanted. I am currently in law school and have a very flexible schedule. I live in Axis apartments downtown Indianapolis and already have a key fob to their dog park.
