Each collar is made of two layers of very pliable, durable vinyl. The underside that is next to your dogs skin is soft and almost suede-like. The top layer is a lifelike animal print fused permanently to the base. Collars are stitched, not glued. Metal fittings are also riveted through both vinyl layers, not glued. Much more durable and these collars won't fray even with the roughest of dogs.
