I honestly would not waste my money on this product. We have received 7 doses and even done weekly/bi-weekly treatments. We have gotten rid of every tick off her body but the moment she steps outside and walks to the pond to play she has ticks again. They get big and never fall off till we pull them. It’s never just one or two either. I have pulled as many as 17 ticks off her after a weekend of fun and she was not infested until weekend fun. It just doesn’t work on my girl. We are looking into more natural products in hopes of better results. The customer service was great and they did try to help us through this issue. The product just doesn’t work and I honestly with I could get all of my money back!
