Comments: This is remarkable I recommend it to every dog owner, small or big. It doesn't hurt the dogs or cats. I use it when they shed and it gets it all the hair you will be shocked the difference in just a brush compared to this. you don't have to stop every minute and clean out the shedder. Like you do a brush, it will ball up for easy clean up and get this, it really gets it all !!!, and it is fast!!! I have a Saint Bernard and you can take the handle a part and run it down his back with ease. And for those needlie dogs like the rasal terrior or heeler it gets all the hair. even the hard to get hair under the neck and the back of the legs. I groomed for a while and if I had this when I was grooming it would have made brushing so much easier.
