Bayer / Seresto collars

I have used a Seresto collar on one of my dogs and am very impressed! I contacted Bayer to ask if it was safe to use on my epileptic Great Dane. Within hours I received a response from Dr Clinton Austin (BVSc). He phoned me and was incredibly patient in answering all my questions. I am very impressed with Bayer and Dr Austin! <br> Thank you!<br>
