Okay, so I know that the old dominance/pack theory has been discredited, so why does one of my dogs appear to be doing it?
4 GSs, youngest 2 are siblings, all 4 are nuetered.
One of the older ones, male, consistently puts the younger male down. Growls, jaws round younger one's neck úntil he's on the ground.
Trainer says he's asserting himself as pack leader. Trainer is a LatÃn American ex police dog handler. Don't know if that makes any difference. He doesn't do the things I've seen César Millán doing, fingers jabbing into the neck or the kick to keep them in lÃne, there's none of that. And everything he does with them is done gently, there's no shoving, yanking or forcing them onto their backs.
Younger dog now approaches older one with his chin almost scraping the floor, like he's trying to crawl past without drawing the attenetion of the older male.
What can I do about this? Younger male has always been moré tÃmido than his sister but is getting worse.
