I don’t think it is ‘fine’.
What I actually said was that there is no satisfactory solution.
The noise must be dreadful, i feel very sorry for the OP.
Yes it would drive me bonkers aswell.
But.
I also feel very sorry for the dog owners because separation anxiety is a very difficult thing to fix and actually, in most cases the owners end up either ignoring it or getting rid of the dog because it proves too difficult to fix.
And because it happens to be a husky posters seem to pouncing on this as reason, but actually, separation anxiety is not a husky specific problem.
This could just as easily be a Yorkie or a spaniel (who can be just as loud) but I suspect if it was we wouldn’t be getting all the outrage of a large dog
a working breed
in a flat 
The reality is most dogs have separation anxiety of some degree and actually, it is VERY possible to keep active working breeds healthy and happy in flats if they are trained and exercised well.
I would bet that when it has company this dog is perfectly content and well behaved in the house, like nearly all dogs.
These owners have done nothing wrong apart from have their dog develop separation anxiety.
Are we not allowed to have sympathy for both sides??
I did not realise you are only allowed to be on team dog owner or team suffering neighbour!
