Having a deep, rough, or hoarse voice; or strong and muscular; or a breed of sled dog from the Arctic.
The voice meaning comes from 'husk,' the rough outer layer of grain, implying roughness. The breed meaning comes from a corruption of 'Esquimaux' (Inuit people), and the strong/muscular meaning follows from the dog breed's impressive build.
A husky voice and a husky dog have totally different origins, but they both describe something rough or thick—linguistic accidents like this happen when the same word gets borrowed for different reasons and meanings merge together.
