Hi Cindy, Over the years, I have not noticed much difference in the way dogs and bitches work. It seems to be dependent on a. the personality of the dog and b. the number of dogs working at any given time and c. how many critters are around. They tend to act differently in the kennel area as opposed to running loose. (The males are more dominant in the kennel.) -Carrie Parks (Skeel Knls)
