Bests & Worsts Reviews from Amazon

Take a look at the photo. She has been wearing the collar for 9 days, way more than enough time for the collar to be 100% effective. Then how does a tick implant itself just 2 inches from the colar, and live? If the tick was on her tail, I could be more forgiving, but this is a joke. Still scratching from fleas too. I didn't buy the collar from the cheaper resellers, to avoid getting scammed by a fake product. This was sold and fulfilled BY AMAZON. There is no excuse for this. The collar is innefective.
