Introduction: I come to your house. I would exercise and walk your dog any time need or as many times a day or night.
I can sit for you, or I come and check on your dog when you cannot be there. If your neighborhood has no busy streets, then I would walk your dog there, but if it is not safe for your pet, I would get permission to take your dog to a nearby park or dog park.
I like to make sure that they get the right kind of excise and be good and tired when they reach home.
