How does levelling and proficiency affect pricing?

Not asking about a specific wolf, but rather a general question of how much more y'all figure a wolf is worth when it has been levelled a bit, and has role proficiencies built up? I imagine this isn't really a set thing and we'll see more of a consensus on this a while after release, but I was curious what folk's thoughts were on it at this point. 

This early in the game it's going to be pretty hard trying to find good pricing for any wolf, but with the amount of times my hunting party has brought me nothing I can imagine others are having the same lack of luck. With that in mind wolves with higher proficiency in hunting might go for a little more compared to those with pupsitter proficiency,  but it just depends person to person.

Some people need pupsitters if they plan on breeding heavily while others might prefer scouts to cover as much territory as possible. I can't wait to see how the economy evolves around wolf trades as it gets closer to full release though, just to see how much the values change!
