Although not having any experience as a dog walker/sitter I have my own pup that I take great care of and I would treat any dog as if it were my own ensuring its safety and happiness during my time with them. I can be trusted to feed your dog at the times it requires fed and go on as many walks as your dog needs throughout the day. If your dog is friendly with others and with permission I would bring my dog along so they have a friend to play with but obviously if I can't then I won't do so. Your pets happiness would be of utmost priority to me.
