This is the best defense for tics in the woods of NH. Since my Rye Guy has been wearing his collar (1 month) we have only seen one completely dead tic on him! I recommend to my sister and she just switched from advantix to Soresto. It is a no brainer! It works better than any other brand and it lasts for 8 months. 5 months if your dog is an avid swimmer.
Absolutely LOVE!! One beauty product I Can Not live without! I keep one in my purse, one in my desk at work, one in my pocketbook, and obviously another pair in my car for precision plucking!! These are the best!
