Usually when walking dogs I stroll leisurely, to allow for them to stop and smell and mark any spots they wish. However, I am happy to jog with your dogs if they enjoy that, I am a relatively active person. I am also happy to take multiple dogs on a walk together (I'd say up to 3 or 4), but I do not plan on overlapping clients (I.e. I won't take unfamiliar dogs along with your dogs).
