So after 6 months use I can review now. Until last year I have for my dog (Labrador 8,5Jahre) a SpotOn uses what he has but poorly tolerated, has pronounced extremely gehaart. In the 6 months during which he has worn the Scalibor collar he had not a tick. So ever met purpose. It is odorless and can easily be attached and detached from what's important to us because it is like to swim and the collar should then be taken to the animals who live not to jeopardize the water. Moreover, I think that has avoided the wet be helped that it worked really 6 months. In the rain we personalize it not settled. Will it buy back for the next tick season. It can also adjust the way, cut if it is too long.
