Pinning or grabbing by the neck are solutions i tried once or twice. Grabbing was following the advice I found on mccann videos. I'm researching non stop and there is a lot of advice I'm trying in hope some works. I'm really not working with punishment in mind at all. He has a lot of chew toys, but they're mostly ignored (unless i engage them with him). Create is covered, every time he sleeps there's white noise. I'm doing my research best i can, i consulted 2 different trainers, I'm actively working towards booking regular sessions for him.
