The Houndstooth fabric, also known as Houndstooth Check or Puppytooth, is a medium-size check pattern with jagged edges, which resembles the teeth of a dog. 

Houndstooth pattern is made out of wool and tweed fabrics and is often characterized by its abstract black and white pattern. It is commonly used for coats and jackets but also very common in women’s dresses and skirts.

History

Houndstooth checks originated in woven wool cloth of the Scottish Lowlands, but are now used in many other materials. This pattern originated in Scotland in the 1800’s, originally worn by Scottish shepherds. History tells us that the Houndstooth pattern played important role in Scottish past. Every clan in Scotland has their own tartan pattern. Wearing someone else’s tartan without permission was more than a good cause for a brawl so to avoid getting themselves in such situations. Scots may began wearing Houndstooth pattern which did not belong to any clan.
