The professional ones are very expensive and so are the blades, but you can get cheaper ones at Walmart and such. They are usually for human hair clipping, but can be used for doing the "clean up" on dogs, too. Clipping, especially on the feet is an art (corny, I know) and can be very difficult, if you've never used clippers before. I suggest taking her to a groomer and asking then if they will do it and show you how.
