Trading Wolves?

So whenever I go to the Trade Center through Crossroads and I try to create one, I notice that no wolves show up in the drop down menu to trade. Why is that? None of the wolves i have currently are newly befriended or are still in the process of weaning, could it be because of my level? All of my wolves have roles, could that be it? Is it something im missing in their settings? 

Appreciate the help!

hi! you got it! because your wolves have roles, you aren't able to trade them. you'll need to remove their roles and then they should pop up in the trading center.
