What is a Swedish Short-Snout?

Newt Scamander's description of a Swedish Short-Snout dragon from the Fantastic Beasts book

The Swedish Short-Snout is an attractive silvery-blue dragon whose skin is sought after for the manufacture of protective gloves and shields. The flame that issues from its nostrils is a brilliant blue and can reduce timber and bone to ash in a matter of seconds. The Short-Snout has fewer human killings to its name than most dragons, though as it prefers to live in wild and uninhabited mountainous areas, this is not much to its credit.
