If they were my dogs, I'd never let things progress like that.
I've heard it said the worst aggressors are sometimes social climbers. The confident alpha doesn't need to fight to win it's position. Which means, quite possibly, the snarling dog isn't the alpha at all.
That snarling dog would have to sit and wait on one side.
Why isn't the owner saying something to the dog?? Is that how she normally is??
One of the least "dominant" dogs of our pack "play attacks" the alpha girl. The alpha girl ignores it completely - it's not worth her time. The little dog play attacks because it's not a full on attack, it's like a "show" of attack (play).
First, I am the owner. The foster dog is the new dog in the pack that initially had no idea how to interact with other dogs and defaulted to fear-aggression. He also bowed up at me a few times before he understood the nature of our relationship. Major leaps forward in his behavior due largely to me cautiously allowing nature to run its course.
What Jäger is doing is not aggression, it is dominant behavior. When the other dogs overstep their bounds he reminds them of their lower position. In turn, Katya does this to Aska (not in the video) as she is the dominant female of the house. Not allowing dogs to measure each other and sort things out is more problematic in my opinion. This is totally different than a bully. All the dogs "play attack" Jäger and he doesn't respond with dominant posturing in that case. Food will, because the rituals around food are very important parts of dog's social interactions. You did not see any fighting in the video, nor was there any risk of a fight breaking out. You saw the dogs communicating with each other, nothing more. It is the subtle posturing that communicates challenges to authority or refusal to submit and this is what I meant to point out in the video.
I have 4 dogs living in peace that eat, sleep, and play together. No fights. So, clearly you could agree there must be some measure of merit in my methods.
"worst aggressors are sometimes social climbers". True, in that this is how dominant dogs rise to the alpha position, if you replace "worst aggressors" with "most dominant". This is just nature. The same things happen in all social animals, including humans (the military, the corporate world, etc). The most aggressive (in many senses of the word) always become the most dominant
