I have a dog that vocalizes when he is either released for a mark or sent on a blind. I have already dealt with his vocalization in the blind and at the line, but it seems he saves it now for when he is released (usually a bark). It also happens when he takes a cast (he takes the cast but usually barks once when given the cast).
What is the best method of indirect pressure for this? Up until now, I've either called him back to the line, given him a sit/nick/sit then resend (which now results in bark everytime he's nicked - which then becomes an endless vicious cycle!), or I'll call him back and go pick up the mark. However the next trip to the line will always result in a bark upon release.
I'm certain the bark is now associated with the anticipation of a nick. I've even tried letting the bark go uncorrected.
Looking for a better alternative for correcting this.
As I said, I've been successful keeping him quiet in the blind and at the line, it is only after the release or cast...
