I started using this product on our two Labs, Daisy and Violet. We walk through fields and in a nature preserve every single day and every single day in the Spring and Fall seasons, they have multiple ticks crawling all over them when we return. We do use monthly preventative flea/tick medication, but both dogs tested positive for anaplasmosis last year. We also have had too many embedded ticks on the humans in our house (we bought this product for humans too!). So when I heard about this product and that it was safe for pets even when using the monthly meds, I thought I would give it a try. I am STUNNED at the results. So far we have not seen ONE single tick after our walks. ZERO. And believe me, that is extremely rare. Thank you so much for making this incredible product. My only complaint is that I wish it came in a bigger bottle. Will be placing another order soon!!
