Hello its_a_zoo_in_here,
that is the clear argument that dogs do not play!
At the beginning it was harmless because the husky thought he could sort it out without showing aggression but could not solve the problem from his point of view.
The owners had the imagination that what the dogs showed is nice and cute.
But it wasn't, both dogs tried to sort this conflict out without blood flowing or skin hurtle. They didn't come to a clear result and now it has to get worse.
This is not the end!!! If you do nothing one day will be a bad situation.
Dogs are pure and egoisitc individuals and not made to share important things, like territory, the owner, love and affection, food etc.
You have no familar pack situation but in fact a forced contact between two foreign similar beings. They have to share but don't want it.
What happenes when two children at the age of 4 yr. are "playing" without supervision. How long does it take to have the first body shown argument?
Seen from the huskies point of view its owner has shown inacceptable and illogical behaviour as he accepted two intruders which doesn't belong to the social alliance in their territory. Territory as the space or the room which is neccesary to survive.
What does wolf pack A do with a foreign individual from pack B when entering the territory? If there is enough food displace it or kill it when not enough food is existing. Nearly the same situation happens in your home with enough to eat.
So what you can do is to show both dogs, that everything is cleared through you and the other human being.
That means: every dog has a place where it can stay and feels safeness, if you have the possibility: in that way they can not see each other.
When you go for a walk then only with one dog after the other. Don't let them in the garden without supervision and take them on the leash, means with every dog seperately.
Food only from hand and not just from hand but let them work for it. We have to work for our money to be able to buy food, so why let the dogs have everything for nothing.
If you would get 5000 $ per month for free how long will you think of your boss?
If you see that they have a special eye contact between them (I guess you know what I mean), block it with your body and give the initiator something to do for you, maybe a sit or an eye contact to you or whatever
BUT don't say it to him, let him find out for himself what you want it to do. That is more stressfull for the dog.
They have to know that if they are stressing you, you will stress them in a higher level.
The attention must lay on you not on the other dog.
Before you can loose this kind of constriction they have show you that the new behaviour has already been established.
Then step by step you are able to lift everything you can take the responsibility of.
