Dog fur (South Loop)

I enjoy spinning yarn, and I'd like to try spinning dog fur! Unfortunately, I don't have a dog :( If you have a Chow Chow, Samoyed Border Collie, Australian Shepherd Dog, Shih Tzu, or Newfoundland (I believe they're also called "double coated" breeds), and are in the South Loop/Printers Row area, I would love if you would save the fur that comes off when you brush for me! Thanks :)
