One thing was REALLY brought home to me on Saturday, at our first Agility trial.
We spend all this time training our dogs to follow verbal commands: sit, down, off, shake (hands), (play) dead / bang!, turn, spin, dance, and so forth.
In two of our runs, we had "traps," also known as obstacle discrimination. Didn't matter HOW many times I said "tunnel, tunnel, TUNNEL!" Willy took the A-frame. Why? Because dogs are NOT verbal creatures. They pay much more attention to our body language. I was running too far over, he saw my "aim," the thing in front of us as the frame and up he went.
YEARS of me being "trained" to give verbal commands, (I've taken 6 dogs through "Basic Manners," 5 through "Beyond the Basics" and "Above and Beyond";) and NOW I have to switch over to body language!
