I don't use them. I use Advantix II as needed. My son uses the Surest collars on his big hound dog, but Chipper is out in brush and long grass on a daily basis with Robbie, as he goes to work with him. (Robbie is an arborist) Robbie comes home with ticks pretty often, and without the collar, Chipper had ticks on him almost daily... Sometimes several. I think that if you are in a highly tick infested area, and you have a big dog who is outside all the time, they may be the lesser of two evils. i think that for most of us with Havanese, there are better options.
