The chairs and brooms is what I use for jumps. To make "wall" jumps I place a blanket that draps over the broom stick and falls to the floor. This way the dog's wont' duck under them and then they also get used to jumping over things they can't see beyond.

Ladders also work. To build a tunnel with a blanket at the end all you have to do is buy a new trash can, cut the buttom out of it and staple a blanket onto the end.

We have been practicing long and hard and have gotten Breeze to jump a jump that is HIGHER then her head!! It was 36' off the ground!!! It was amazing! Breeze loves to jump and play though.
