Here is a nice cozy cowl for my doggie! The chunky, soft rib knit makes the cowl stretchy yet snug for easy on and easy off while providing extra warmth. It stretches to almost double its flat size and can fit a variety of sizes and shapes. Can also be worn unfolded to cover the dog’s ears. It is knitted in the round from the bottom up with an optional buttonhole for the leash tab.
