This is the best item I have purchased in a long time. Having 1 dog and 2 cats inside the house most of the time, there is ALOT of hair. Normal brushing helped some, but not near enough. Even after the first time of using, the quantitiy of hair was at least half. Now after a few brushings with Furminator the house is liveable--much less hair. I am very impressed with the results and it works fine on my medium size dog. All the animals love it. My cats purr the whole time.
