Absolutely I feel sorry for the OP.
The noise must drive her bonkers, it certainly would me!
But I think it is a shit situation all round with no good resolution.
No dog breed is immune to separation anxiety, they are pack animals.
It has nothing to do with being a husky.
Plenty of potential issues like poor train ability, mega high prey drive etc could be attributed to it being husky.
But not separation anxiety.
There is no breed ‘unlikely’ to get SA because it is a universal problem.
I think it is very difficult, if not impossible for the owners to fix.
Training is, afaik, desensitisation over time which would require time off work which they probably can’t get.
Daycare/walkers costs an awful lot and it is something that probably wouldn’t be factored in when getting a dog for most people, and it may not be suitable anyway.
Sure, they could get rid of the dog.
But aside from the cruelty aspect of the dog being kenneled, suffering and potentially being placed in a new home not as nice as the first it would create massive neighbour issues.
Speaking from experience, some people are batshit crazy and can make your life a living nightmare, far worse than 4 hours of dog barking.
