We were sold First Shield Trio for our dog. 21 days later, he was scratching and we found attached ticks. He doesn't swim, etc. I will not buy this product again, and if you report the product failure to 1-877-872-3744 you can get a refund from Banfield. Lymes disease is no joke, and if they're giving people a false sense of security they need to be held accountable.
