“So far so good with these collars. I used Soresto in the past and typically pulled off a few ticks each season although the tick was paralyzed so the collar worked. This season have not even seen a tick so assume these collars repel them. They actually smell amazing too! It's great to not worry about poisoning my dog or myself! I have a small dog rescue and I am now using these on all the dogs I bring in to my rescue.”
