Selling Mother with Puppies?

hi there!! 

I've seen a lot of trades where a user is selling a mother wolf and her puppies, but this option isn't available for me. 

I know the mother can't have a role, and the puppies need to be weaned to sell separately... but what are the rules for selling them altogether?

thanks in advance !! 

You should be able to.

I'm not if the bug has been fixed or not? Try moving her into another cave, that sometimes helps.

EDIT: She is still a sitter.

thank you both! I changed her den and the issue corrected itself. :)
