Absolutely!! I used to walk fairly regularly, but Mr. Wonderful keeps me doing it every single day (well, almost--we'll skip a day if it's raining hard all day), and for much longer than I would walk on my own. Before him it was easy to skip a day or two, but knowing that skipping means having a 65-pound ball of energy cooped up in the house all evening is the extra kick I need when it's really hot or really cold or whatever. It's great to have the company; it's great to have the motivation; it's especially great to have the protection in case of a possible problem, particularly in summer when it's too hot to walk until after dark. (The only thing I have to worry about when walking him is potentially being charged/attacked by an unleashed pit bull; that's why I carry a good sharp knife, too.) It's great fun to take him to a fenced area and throw the ball for him or run around playing Keep-Away, which we also do in the backyard. And for Xmas this year I want to get one of those bars that attack to your bike and then to a short leash, so your dog can run alongside without being able to get in front of or behind you. I'm very excited at the possibility of adding biking to our routine!
