Hallo.also actually I was very skeptical. But after visible fleas (ie a saw and do not get caught) ordered the shampoo. Was the next day there and was also applied the same. Dog wet, shampoo top-3min act lassen.abgespült and dried. Examined and dog: 3 really dead fleas and a dead tick gefunden.super stuff what pleasant furhund and Herchenhainer riecht.ob it 7days persists we will testen.aber price and the results are fantastic. Is definitely coming back into the house.
