I will not walk more than three dogs at a time I would like for all dogs to have a certain amount of attention. Second their safety is important so I do believe in having them on leash, so we are not setting them up for failure and or to get lost or hurt. Third learning a little bit of their background and their history so that if I need to walk a dog on a solo walk I understand that not all dogs get along with others but I want to make sure those dogs also get walks :)
