By the way, I don't think I've mentioned this before.
For the last several weeks, and for the foreseeable future, Laddie is wearing a collar with a tab, a 9" lead.
If we ever have a chance to train with flyers, I'll keep a firm grip on the tab, but keeping slack unless Laddie attempts to break. Because Laddie wears the tab all the time, he won't associate it particularly with flyers. He'll just re-discover that breaking doesn't work.
Beckie we can compete again, it's essential that we practice in situations that look as much like events as possible to the dog. If Laddie figures out that an event context predicts the availability of a self-reinforcing break -- at the minimum, the immediate pleasure of a high-energy outrun -- we may never dig out of that hole.
I don't know whether we'll ever have an opportunity to give Laddie that training. But at least we're laying the groundwork by habituating Laddie to the tab in the meantime.
