Unlike other dog garments that are mainly fashionable, sun hats also serve a practical purpose. Dogs’ eyes are sensitive to sunlight. A sun hat blocks direct sunlight from reaching their eyes, allowing dogs to see and manoeuvre better in extremely bright conditions. If your dog’s face lacks protection, harmful UV rays can cause sunburn and contribute to eye conditions like cataracts and pannus. A sun hat reduces the risk of such medical conditions and helps preserve the health of their eyes in the long run.
