Because they are very difficult if not impossible to train on a reliable recall :-(
As small pups they are very responsive and owners get more & more confident that 'they' are training their pup well and that the Breeder, who if they are worth while, will have spent hours drilling into puppy buyers that they cannot be let off the lead, do not know what they are talking about.
However with age comes the spitz mentality of 'why should I do that' - anyone with spitz breeds will know this :-)
With a Sibe this manifests itself mainly into 'why should I come back'? Baring in mind they are a very primative breed, with their main purpose to run & pull, they run at great speeds, covering a lot of ground in a short amount of time. They run straight, not quartering as a gundog might, nor circling like a herding breed. They also assume they can outrun danger...be it a car a train or whatever :-(
Having run for a long time, they do not return, being of relative independent nature (not a one man dog) and also having quite a high prey drive, they will happily hunt...not good when it is sheep and the farmer is there :-(
That is why, in the past, most people serious about the breed in this Country worked their dogs in harness. To be honest they are a nightmare breed in many ways, for all their beauty.
Due to films, press attention and general changes in breeding & breed popularity the world & his wife now breed huskies. Whereas once unsuitable people wouldn't have got a dog, you can now find numerous web sites, order on line & have your own little furry bundle in no time at all :-(
Welfare end up picking up pups as young as 8 weeks from homes that wish to put them down :rolleyes: who have signed contracts NOT to contact the Breeder

Ooops sorry....you didn't really ask for chapter and verse ;-)
