Huskies are beautiful and powerful dogs which have been bred for many years for use as sled dogs. Originally bred by Artic indigenous tribes, the fastest and strongest dogs would be bred to produce the most efficient sled dog possible. The breed has now had various types registered with the Kennel club including the Siberian Husky, the Alaskan Husky, the Mackenzie River Husky and the Sakhalin Husky. These impressive, athletic and energetic dogs often have pale eyes, usually blue and in many cases heterochromic. They grow dense double coats to allow them to withstand low temperatures and they can be a variety of colours from black through gray, to coppery-red or even white yet they always have the lighter tummy and underneath. Huskies are more prone to an eye problem known as Uveitis that most other breeds. Huskies are usually a fairly large breed of dog that lives quite happily in households with more than one dog, and although they can make fantastic family pets they can sometimes show an intolerance to smaller children and cats!
