Thank you for giving us our walks back!! My pup, a one-year-old whippet mix, LOVES to run through the grasses in the local foothills. But recently we had a few close calls with foxtails, so we had to keep her leashed and on paved streets. Then I bought the OutFox Field Guard, and Coco took to it immediately. She was soon racing at 90 miles an hour through the tall grasses and couldn’t have been happier—and I was able to relax knowing she was safe. Great invention!
