I see alot of them shake, pull and let go after the hog is dead. Which is fine by me, as long as they are caught solid until the hog is under control.
I always choke them off. I leave 1" collar up at the top of the neck and pull straight up... eventually they will release to take a breath. Some may take a little longer than others... but any catch dog will come off like this.
I gave up on using break sticks because I always lost mine!
The blowing in the ear does work... Krystal showed me on Cliiford last year.
