I have a 2 yo gelding PRE that I had first dualty session with.Worked on basic walk and stop and ground manner as in video. The halter seemed to stress him alot and after 40 min of work, he started to hypersalivate. I've read that sometimes dualty can press on facial nerve and cause hypersalivation, but that also high stress can cause that. The stress and salivation stopped as soon as we replaced dualty with a rope halter to finish last 10 minutes of work. He was much calmer with rope halter.
Any idea how to avoid that ? Aslo, should I work through anxiety with dualty (It seemed to get better during 40 min we worked, salivation aside) ?



You do not mention performing Join up. Whilst it is possible to make good use of the Dually without Join up, with such a young animal it is a significant omission & whilst much can be learned from the videos, only practice can perfect the skill of the Dually art. I would urge you to continue to study Monty's methods, perfecting your body language & Dually head collar skills. With my youngsters I found keeping the sessions really short to start with, so only one or two positive reactions met with much copious praise, gave wonderful trust & cooperation. The lessons on 'coming to the mounting block' show how effective a really light touch & lots of praise can be. Good luck & keep us updated on how things go. Cheers, Jo.
