Dog fibre is very interesting. On the West Coast of Canada, the
local first nations people had a specific breed of dog they kept just for the fibre.
(note, 'wool' in textiles refers to fluffy stuff from sheep, all other animals make 'fibre' except the American ones who make 'fiber')
Some European traditions had dogs that were as fluffy as sheep. They are usually heard protection animals like the
komondor. These guys are huge! When my friend shears her sheep, she also shears her komondor dogs and treats the dog fibre just like she does wool.
Dog fibre can be very soft, especially if one is just using the undercoat. It's surprisingly popular around these parts and I know several spinners who process it. But a great deal more who won't go near the stuff.
I suspect the dog smell is dependent a lot on the dog's diet. Sometimes the fibre stinks of dog, other don't. The fibre that doesn't smell when wet seem to be from dogs who eat homemade food and not a commercial diet.
