Westie Doormat - Personalized West Highland Terrier Welcome Mat Available in 3 sizes, 16"x24", 18"x30", 24"x36". Our coir mats are professionally printed using high quality UV inks to reduce fading, and have a non-slip PVC backing to help keep it in place. We recommend that you keep your mat in a dry, covered area to prolong the life of the design. To clean, simply shake or vacuum away any debris.
