Fighting white line disease in my mare. She has it in all four legs. We use Clean Trax, which requires each hoof to be soaked for 45 minutes, and we also soak the hoof in Epsom salts. The bag is in very good condition. Luckily my mare has a calm demeanor so she stands by her treatment. Positioning the pillow correctly can be a challenge, especially on the back legs. I recommend positioning the pouch and then adding the soaking. When moving, the bag can also slip off with straps, but the liquid will still cover the hoof. I think I will buy more packs to speed up treatment.
