There are various brushes and different seem to have better luck with different ones. I like the wire slicker brush.
I was given a Furminator. It seemed to do about the same job on my labs as the slicker brush, only slower. when my son was here in the spring I tried it on his Fox Hound. It seem to work well.
I was given a stray to keep a few year ago. He looked like he could be a purebred Husky, beautiful eye spots. I named him London. About a month after he went to school, I had to pull our kitchen range out. Gone, but not without a trace.
