I have been working with all different types of dogs my whole life. Ive owened Great Danes to Chihuahuas. Recently have been walking and sitting dogs for friends. Dogs have an energy that you don't get from working with any other animal or human. I have found working with dogs makes it more fun to "work". I currently am unable to own my own dog, but am very excited to be able to help other owners out. My roommate has a Chihuahua and a red healer I watch sometimes. I also enjoy getting outside and being active. If your dog likes to jog, I don't have a problem doing so. Fetch or the dog parks are also fun alternatives, if I know owners are ok with it.
