For centuries, caribou skin lodges (ekwo 
  nihmbaà 
 
  in Dogrib) were the most common form of shelter for the Dogrib. Making a lodge 
  was a long and difficult task, involving several steps and requiring many caribou 
  hides. Once made however, they offered protection against the elements, and 
  could be easily packed up and transported.
Sometime during the early 1920s canvas began to replace caribou hides in the 
  making of lodges. During a period of transition, hybrid lodges - part hide lodge 
  and part canvas tent - were occasionally used.
