I received this product free on exchange for my review. By the time I received the product I had already started using a seresto collar for my 4 month old German shepherd. So I removed the collar and applied this topical treatment. For the duration of the treatment time I did not notice any fleas but did find some ticks, although they were dead. It did seem to keep my boy protected, but he has had continued itching at the application site. All in all, the product worked to prevent an infestation, but I can't speak to it's ability to treat a current infestation. If your fur baby has sensitive skin, use with caution.
