Query: Wonderful!!! Best invention for pet owners yet.

We have a Chow Corgi mix who sheds everywhere. Not to mention the three cats and two other corgis. This was wonderful. The pics are not staged you will get that much hair from your pet in minutes. I have not figured out how it works exactly but it does. It doesn't leave your pet bald or looking like it is missing that much hair. We have used rakes and undercoat brushes before and nothing has got this much results. Our house is now less hairy and I do not have to carry the lint roller around with me in the car anymore. I have used it on all the pets even the independent cat and they all love being brushed with it. This is just a wonderful, wonderful, wonderful tool.
