I’ve owned large dogs to tiny dogs boys and girls. Dogs generally gravitate to me I laugh with them talk play run pet everything that dogs like. Teach my dogs of lot of different commands through out the years. Letting the dog feel free but at same time let them know there are boundaries that can and can’t be crossed . Talking to the owners and getting all the information you would possibly need just in case something bad was to happen or even if good things are happening. Dogs are great but still animals and can’t predict every move they could or would make. With this being said and done communication from all angles is best for all parties for a happy and successful walk.
