Toward Ecosophy

On the off chance any of my readers happens to be fluent in Korean, I'd like to ask for a little help here. The Korean dictionaries I've been able to find online give two words for "wolf" -- neugdae and ili (or, in one older dictionary, iri). Which of these is the correct word for the animal shown on the left -- and if both of them are, do they have different connotations, or are they used in different contexts?

In case you were wondering, this is for a fiction project, the current sequel to my just-published novel The Witch of Criswell. One of the continuing characters in the story is a young woman with a Korean mother and an American father; she's fluent in Korean as well as English; and she's taught main character Ariel Moravec a few useful words of Korean. (They're a couple of geek girls who are into old novels, old movies, and magic, so that sort of thing follows naturally.) Since wolves, and also werewolves, are a central theme in this novel, I figured I should get the word right!  Thank you in advance for your help.

(And yes, I know about the hairstyle called the Korean wolf cut. It may or may not feature in the story at some point.)
