Hindquarters cotton dog collars are strong and durable but also comfy to wear: the cotton is soft-to-the-touch with flexibility and give, so suitable for active and busy dogs. The collar is adjustable for a perfect fit, the buckle is easy to fasten, and stays firmly closed. Just machine wash at 40 when mucky.
