We have a fun course set up at the field. The course is built around a double box. Since my accell/decel workshop, I've been out there playing with the dogs. Even Olive gets to play with the jumps on the ground.
This is my first time working her where I'm running as fast as we can. Need to practice that alot. She likes to turn, she doesn't like to go straight. I'm using this drill with tunnels to get her excited about going straight. The big deal about this set up is to toss in a ton of decel so your dog isn't just running from tunnel to tunnel but is actually listening to you.
I've put up three of the drills I was working on, but the possibilities are endless.
