How to put a wolf up for trade?

Hi, I’m on my 4th day of gameplay, and I’m trying to figure out how to put one of my lower-stat wolves up for trade (instead of chasing her). I found the tradeboard, started a new trade, and I see the box towards the bottom to enter wolves’ names. When I type in her name, nothing happens. Can someone please tell me what I’m doing wrong? I’m playing on mobile, if that helps! 

Thank you! :)

Check if the wolf has a role set or still on cool down.  Those are the most likely culprits.

Ok, I learned that you have to remove their set role to list them for trade. Thank you! :)
