We live in an area that has lots of foxtails. Each spring, our dogs get foxtails in their ears and eyes. This year, we tried the OutFox Field Guard, and the dogs have not gotten one foxtail! Due to the rain this year, the foxtails present a huge problem for our shoes and socks but not for our dogs! The dogs quickly adapted to the Field Guard thanks to a few treats we gave them during our first hike with the Field Guards on. They are easy to put on and take off. We heartily recommend using the Outfox Field Guards!
