Bear costume for pet / dog size small or medium

I bought this for our 45 pound German shorthaired pointer, it’s SO SMALL! It says it’s size large but no way! Was too late to return it. I’d say it’s a small or large. It was worn by my pup for two minutes so we could see how absurdly small it is on her. It’s new condition with a spot on the bow, can be seen in pic.
