I've been walking a sweet Great Dane named Dexter. He's spotty and strong and I have to walk/run just to keep up with his loping gait. I've worked with big dogs before and mostly I prefer them, but he is by far the tallest with his back just about at my waist. We've gotten into a routine and he's lucky enough to have a person who has chosen not only a very pet friendly apartment, but it's also right next to a trail that is easy to get to. Dexter is a bit skittish around screa
