Nema had a great time jumping over tunnels, running through tunnels, running over beams, weaving through poles, and teetering on a see-saw. It was great physical exercise, of course, (for both of us, actually) but also it was challenging her mentally to learn new things. And it helps reinforce her obedience training.
The below photos show us starting up the beam, Nema running across it, and then down the other side.
Nema also learned to weave between poles, as shown below.
Although she was initially a little unsure of what to do when going through the tunnel (at first she just kept jumping over the tunnel) once she figured it out she loved running through it!
