This one is already the tool, and with a vacuum hose attaching end. 

If you have a very small dog, this might be too large a width of comb for your dog. We do not need it, for we adopted our Jack Russell terrier (shedding fiends) to our daughter, and we had taken in a poodle, who do not shed at all (but do need professional grooming regularly).

This has never been used, for we would always just take the dog to the back yard and let the fur fly outdoors. But if you live in an apartment, or it's the middle of winter, that may not work for you.

 

The photos show the product, we do not have any of the original packaging.
