good call on keeping the pants and hemming them.

That video is HILARIOUS! We have a golden retriever and it's the same thing. I take him outside and brush him and his hair litters our yard like snow. It naturally comes out in puffs/clumps. We call them Jimbo puffs.
I love my animals- I hate their shedding. At least when I shed (skin, etc) I don't have to see it everywhere- if I did I'd probably be oooged out.
I gave up trying to "roller" the hair off my clothes years ago...
