This is a brand new Gryffindor dog sweater from Bark Box’s Harry Potter line. Size is XS/S. It was accidentally duplicate ordered for a pup who already owns the exact sweater, so I know it fits a pretty average sized Cavalier King Charles Spaniel (15 lb) nicely and holds up well to wear.

(Though this sweater has never been worn and is in brand new condition, the above CKCS, like a true bold Gryffindor, did go after the tag so that’s gone now)
