I would recommend starting with tricks that involve movement. Circles, spinning, figure 8, backing up, jumps (if your dog is old enough/ not still growing) etc.
Jesse is truly an incredible, talented dog. I hope seeing their videos inspires you and gives you a glimpse of what JRT's are truly capable of! Especially take note of the relationship that he shares with his owner and that they train exclusively with positive reinforcement! :dogbiggrin:
