Ordered 3 capsules for weight 20 kg, by mistake, my dog weighs 6, but not the question, all the means used to this, helped not including Front Line, which is more expensive and smells of chemistry! And then a wonderful tool, natural, environmental, and my dog just loved not prevzaydonnom. 2 capsules for the summer never itched, and where he shared all blohi.Teper Aherb only, and only this company. I recommend to all !!!
