Had the lice comb now also times in use, because our dog has fleas captured by a hedgehog from the garden. The comb can be run well, even on the legs. Caught almost every louse. Cleaning is also very easy. Quality makes itself felt.
Our dog has very short hair (French bulldog). He seems to enjoy combing correctly.
What is the handling when langharigen races I can not judge. But the self-test it has something geziept to your own hair :-)
