I'm looking for a great walker for 1 dog. Diesel just needs to go potty during the lunch-hour and we live in a town-house with no yard. He is a sweetie with people but too big for my mother-in-law to walk. He is a black-mouth cur, (think yellow-lab mixed with coon hound) about 100 lbs, and 11-years old. He does not like other dogs, so we walk a wide-berth when we see them. So far no problems with anybody, but with his size, we don't take chances. We are near 104th & Federal. There's a lovely greenbelt nearby. He is a great walker. Doesn't pull or bark. My neighbor was walking him, but got a new job. She can offer a reference to his great walking skills if you like.
