I had posted earlier about not getting any fur off with the Zoom Groom, but now I've figured it out. If I just rub him all over in circles, and then use it to brush off the loosened fur with downward strokes, a real little cloud of white fur accumulates on the floor. It's brilliant. I now use it when he's in a dry bathtub to catch everything. No such luck on Lola the Pug, who needs the furminator. So, the furminator won't work on my Frenchie, but the Zoom Groom won't work on my double-coated pug.
