Product Description:This is a extra small multi color, striped, wool hood/cowl for 5-10 lb. dog. The yarn used is a wool/nylon blend. This size would be perfect for a chihuahua or any other dog of comparable size that is very sensitive to cold temperatures. The last photo is not the color or size of the hoodie that you will receive. This photo is simply used to show how it will look on your dog since I don't have a model small enough to photograph wearing this size hat.
