Was a bit disappointed with the detergent. Fortunately, it has the coat (large normal Longhaired piece) does not destroy (That was my main fear). However, it is also not become as clean as I expected. Maybe I should have taken twice the amount. But I just kept at the predetermined amount. Perhaps it is also not in the detergent and the fur is anyway darkened over the years. After drying, the coat must be by brushing well to make it look reasonably presentable again, however again.
