Cash is conditioned to "engage - disengage". This is about 25 yards. I love the long line as I feel he doesn't feel restricted. He's really overcome being a total nut when he sees other dogs. I'll take management over a freaking reactive nut job anyday!
Well, he went out the door without being released, BUT he did stop, on command, from his pursuit of the vicious squirrel!
Training is a daily, ongoing effort. Up the distractions and strengthen the impulse control...
His leash reactivity used to include an over-excited prey drive / to chase moving things.
