Ordered the FURminator on my puppies 15 weeks, from mixed breed Dachshund and French Bulldog, since it really strong HAART at the moment. Was sadly disappointed, though but get out a lot, but since it has very short, very soft fur, it's just so much more effective to attract normal rubber gloves and to "brush" with it. Think of FURminator works at boobs etc really good, our fur is but I think too fine and too short ... I have also found that the brush with the metal brush FURminators attacks the skin of my dog, it peels increased, although I gently so handled am ... is probably really only for dense short coat.
