Our beloved Dogs (Sadie and Cleo) seem to have started shedding more and more - that or we have just become less and less tolerant of dog hair and dirt as of late. I did some reading and decided to try out the much acclaimed Furminator. Now I had been brushing the dogs a couple days a week with a rubber-brush-mit-kind-of-thing so I was also truly AMAZED at how much dead undercoat this great little device extricated from the dogs (and indirectly from my vacuum cleaner). The reviews are true it seems. The head consists of several very fine teeth, that individual would undoubtedly puncture and/or cut the skin; all of them together however form a comb that isn't any less comfortable than other dog brushes I've used (and I tried it on my arm to be sure I wasn't hurting the dogs). Two thumbs up!
