I had no experience in the grooming and have therefore made smart in Dachshund book.
This trimming knife I bought because of the positive reviews here and because in the article stating the score is suitable for rough skin.
On the package back is a quick guide, this is easy to understand.
Within 30 minutes I have brought enormous much undercoat from the fur of my Rauhaardackels, the mountain next to the dog was almost as big as the dog itself!
The longer one trims the more experienced are the handles and my dog has comically kept relatively quiet (at brush it disengages).
I am very happy with the result, the skin is soft and has great shine and my dog no longer HAART much.
This is first again for the next time rest.
