Belle, Dusty and I went to a NADAC trial last weekend hosted by 4RK9s in Davenport, IA. I had a chance to tape the Chances runs on Sunday.
There are four main challenges on this Chances course.
1. The send to the tunnel under the dogwalk.
This task can be made somewhat easier by angling your dog toward the tunnel at the start line. Something I forgot to mention until near the end of the video.
2. The send to the tunnel in the upper right corner.
When you watch the video, notice the great variation in commitment points to the two tunnels. Dogs that commit early allow their handlers to move much sooner toward the next challenge than those who require support until they are almost in the tunnel.
3. Sending your dog over jump #7.
Notice that on the Elite course map, the distance line running from the right edge of the course to jump #4 echoes the path the handler can take to support the dog's line to jump #7 and hoop #8. This is not true of the Open and Novice courses. If the handler follows the line on either of those courses, he is very likely going to draw his dog away from #7.
4. Sending your dog out to hoop #8 and bringing him back through hoop #9.
On the Novice course in particular, if the handler is on the line, there is no way for him to move toward the #8 hoop.
Here's the video with my commentary. I hope you find it helpful.
