I use this collar for my dog already years, works really well in the environment with medium tick appearance. At the beginning I wanted something natural, no harm chemicals, as the dog is in close contact with the kids as well. I love the smell and appreciate that it works really well even if my dog swims with it regularly. I will continue to use Menforsan as the philosophy and their products suit well my demands for quality/animal welfare/natural components.

Huele muy bien que no molesta a mí chihuahua, se lo cambié a los 3 meses como pone y seguía oliendo
