Wolf Skills When Traded/Sold

I've asked this in two other places though haven't gotten an answer so I'm going to ask here where it's more stable and less quick moving:

When you trade/buy a wolf so long as it isn't chased, do they retain their abilities as far as hunting/scouting? So will your chaser wolf still have 15 points in chasing if you give him to someone else, or are their skills tied to the den/pack they're in while they're in it?

In short, do wolves keep their hunting points when you trade them?

They should keep their proficiency even if sold/bought. You can check a wolf proficiency on the Pack Role tab in their personal page.

Remember that wolves lose 1 proficiency point for every rollover, so if they are on the Trading Center for some days, they could lose some proficiency

Hope I was of help!
