The Lead Leg
The lead leg is NOT the leg that's fartherest forward at a given moment. It's the last front leg the dog lands on in a single stride. Turns out, it’s the leg easiest for the dog to turn into.
Halliliulih! So, the significance of the lead leg is about balance and direction. The dog landing on the wrong lead leg in a turn tends to spin away to regain balance, or turn wide as they add an additional stride or two to change leads. Changing leads requires a skill just like when a kid gallops along like a horse, then adds in an extra hop to change lead legs.
Giving turn cues before D takes off over a jump helps D change lead legs before the jump and land ready for a tighter turn.
I'm making further notes as I read through this "required reading" book in conjunction with Daisy Peele's Online "Agility Foundation" class, which I am auditing this winter. I will post my book and class notes when I've completed them, or maybe break it down into different topics like this one.
Upwards and onward!
