Our bandanas are 100% cotton with overlock stitching on the hems to ensure rugged durability, free from fraying and raveling. Size Small is a 14" x 14" square that is easily folded in half to create the triangle look needed. Roll the bandana until the desired length down the back has been achieved, then tie around the dog's neck. Size Large is a 22" x 22" x 31" pre cut triangle. While this size will fit most breeds of dogs, we recommend rolling the bandana to the desired look before tying around the pet's neck. Our designs are placed in the lower corner to allow for this.
