I'd like a visual indicator that a wolf is your progen. I mean, you know your progen. But let's say someone visits your den and you have a bunch of wild wolves together. Your profile pic might be an indicator, but what if you aren't using your progen? The only way is to you, yourself, type that a wolf is one half of your progen couple.

that would be cool tbh I like this idea

I'm neutral on this :O on one hand I see it as helpful so other users know a wolf can't be sold/traded, but I'm leaning towards the idea of not putting an indicator just because I know some people like to “replace” their progens for a pair of normal wolves, and the lack of a progen marker would probably personally bother them if it was implemented ;;

Support

I think this would be helpful in identifying if a Gen 2 pup is from a Progen or not as well, for those who value that sort of thing.

I have no issue with the idea but would prefer if it could be hidden; I wouldn't want anyone who is happy with the current system to be upset by a change, and it's not like you can't already indicate your progens if you want to!

Personally I'm indifferent for my own wolves but also I think it's pretty obvious who my progens are if you look at my lair lol

Support as an optional feature that you can enable/disable in either your profile or your progens profile for the same reasons Dottler and Luke mentioned! I'd personally use it but fully understand the reasons someone might not want this!
