My past Lab and GSDs shed a whole lot. You know what I used that reeeeeeeeelly works? I've always had horses and I used a rubber curry brush. It's got a couple of rows of blunt, firm (sort of triangle shaped) teeth around it. It's oval. And it has a strap on the back which you put your hand through. It doesn't look like it would do anything, but you would not believe how it gets dead hair out....bags full. I could have knitted a lot of sweaters if I had the inclination and skill. I'd stay away from the knees and other small, bony areas, but for along the sides and back of the dog, even the tummy, it would work well for you I bet. You get it at a feed store.
