Looking at this thread, Emma would certainly be good at the jumps. She just loves to jump. And when she jumps on the couch, she hits a pillow or the back of the couch as if she is hitting a target. This she learned on her own.
I'll have to try the lawn chair set up. What do you do for tunnel training? Would putting lawn chairs together and blocking the sides work?
It would be easier than buying a jump. For tunnels, Emma just goes under the chairs. She has made up her own game of playing fetch - get the ball, go under the chair, then return.
Question - how would you know without investing a lot of money into equipment etc. if your dog has the ability and attention span to even attempt this? Emma is a dog that I have to keep busy.
