@Scarla it's easy enough to look up the wolf and see she is not released nor is she a progen.
You can simply click on one of your own wolves, then in the browser bar replace the wolf's ID number with 9176 and it will take you right to the wolf's page. From there you can see if the wolf is released and if not, whose den it is in. Voila! However, it is a 4 digit WW so likely to cost a pretty penny if the owner is willing to sell.
