Miniature versions of the husky breed existed long before the 'fad' became popular in the US, back to the beginning of the origin of the breed, in Siberia. Smaller versions of huskies existed even back then.
The miniature husky features a size of 12-14 inches at the withers and weighs in at 16-18 pounds. What use were they? Obviously being too small to pull a load, they were used as hunting dogs (although how they were trained to not eat the prey escapes me). The only difference between a miniature husky and its standard size cousin is size. As far as their temperaments, health, and stamina are concerned, there is no difference.
This brings up the issue of how to keep, train, and live with such a dog. They will howl just like a standard version husky, they will show the same independence and 'puppy destructiveness' as the standard version: but, since they are smaller, they might be easier to handle for someone who does not have the physical strength or experience to handle a standard sized husky.
If you ask me, this is not of great advantage, because mental/emotional strength is much more important in handling any dog than physical strength.
North Carolina claims to be the first state in which the 'modern miniature Siberian husky' was bred, and specifically, the city of Hendersonville, NC.
In order to settle a much disputed issue here, let us ascertain that the miniature husky is NOT bred from runt of litter stock, dwarf stock, or other considerations that would rightfully be called 'negative'. This is not to say that some opportunity-minded individual would shy away from using such practices to pass on some offspring as 'miniature husky' when, in fact, the poor puppy is just 'defective'. Always check out the reputation of the breeder before acquiring any type of dog. That's just simple common sense.
Miniature huskies were known as 'Tungus Spitzes" by early explorers. I can only guess that their reputation wasn't passed along as widely as that of their standard sized cousins ...
