Well i was taking Chesty for are normal evening walk, when we are walking along and a deer wonders across the road, chesty stopped got in his bulldog stance and just stood there and watched the deer cross the road, no barking or growling, once the deer crossed and made it into the woods Chesty and i continued are walk...but every 5 steps he would get behind me and turn around and check to see if the deer was following us or something and he did it the whole way till we got passed the woods. I think it was his way of protecting me. or he was just really curious about the deer because he never seen one.
