I am afraid some people buy on a whim, without any thought at all!!
I'm sad to say that I think some people nowadays see all sorts of animals as something they can have when they want to and dispose of when they get too big/destructive/noisy/hassle. Then, instead of looking at what went wrong and readjusting their behaviour they go and do it all again
There's no commitment to finding out about them (either before or after they buy them) and the poor animals get the blame for not fitting in with the owners plans or lifestyle
Huskeys are a beautiful breed of dog, absolutely stunning and I can understand why people would be attracted to them (Akita's too) but surely anyone with any kind of sense knows they're not a family pet type dog
A quick google search tells you they need to be 'worked', they need an escape proof garden and they need firm control from experienced and dedicated owners - people either aren't doing research or just aren't thinking properly.
Putting your desire for an animal over it's need for certain conditions and care which you can't provide is just downright selfish, and it's the breeders who sell into those types of situation that cause the problem IMHO.
