NWOT Mark & Graham Knit Santa Dog XL Sweater

Just bought it online from the store and it's too small for my dog. The size is X-Large (suited for medium sized dogs) and there isn't the name Teddy on it (it has no name on it). The original price includes the shipping costs I paid. EXTRA LARGE • Recommended for Medium Breeds. • Chest Circumference 24”-27” • Body Length 16”-18
