The dogs can do the horsey obstacles, but not the other way around. We were at a schooling show one time, and during the lunch break I took my Choc out and ran her over the hunter course (she can jump the moon - a 2'3" hunter course is no problem for her at all, she jumps just under two feet in actual competition.) She even did the trotting circle before and after the course. She was so excited at the applause that she did the famous Lab 'butt tucking' display - where they tuck their entire hind end under their body and run madly in circles, swinging their ears around . . . . it is really odd looking.
