Dogs with good intra-species social skills are able to meet and greet another dog on loose leads, without lunging at one another or dragging their handlers along the sidewalk. Since normal canine meet-and-greets involve a mutual circling investigation, it is necessary to follow your dog around in a circle to avoid tangling leashes. Donaldson empahsizes the importance of maintaining "high situational alertness without any telegraphing of tension to the dog:" you should be "bubbly loose and happy on the outside, but vigilent and planning for emergency break-aways on the inside."
