Someone at a show told me they use this and that it's much better than a curry comb. I haven't bought/tried one yet, but their dog's coat looked great. Wonder if anyone else has tried it.
I find that zoom groom brushes do NOT work on my dogs. I like a slicker brush and a fine toothed comb for getting out too thick undercoat.
Yes, I use a rake also and just love it! Especially in the beginning when there is so much coat and they are just starting to shed. It is great at getting out gobs of fur in just one stroke. Have an empty trash can handy, you will fill it up in no time!
