I have one dog, a pit bull, and a cockatiel. I've dogs before ranging from small dogs, dachshunds, on up to large dogs, German Shepherds. I do live in a mobile home so there isn't much of a yard, but it's big enough to run around and play. I'm wanting to become a doggie sitter to give me something to do to break up the monotonous daily chore of being a caregiver. It will also get me to start being active instead of sitting around a lot like I normally do. I never know, I may start to lose weight as a result of being active and have fun in the process with all the doggies. If there's anything else, I'll add it at a later date.
