SWSW have some super duper grooming brushes to help with fundraising.
It's two combs in one brush, great eh!!
One side is a stripping blade, and I'm not just saying this, but it is the best one I've ever used, on a recent camping trip I groomed Titch to within an inch of his life before we left home (he really gets a thick undercoat) and while we were away I borrowed a friend's one of these and I got a whole load more hair out of him, I'm talking loads, that's when I started to source these for fundraising.

The stripping blade removes all the undercoat, the dead hair that just makes your dog's feel hot and leaves the top silky top coat and then you have the grooming rake that removes all the stray hairs and keeps your dog's coat tidy.
To back this up the handle is really comfy to hold.

To top it all off there's even a choice of colours as well
