Befriedning wolves

Hello! I find it quite easy to befriend most wolves, but I've lost few pretty nice wolves because of their stoic personality... How to act while befriending stoic wolves? Almost all options give them negative points, even "relaxed tail", which I thought would fit their personality...

There’s a guide on how to befriend all the different wolves over at user-created guides, I think it’s a Grouse House guide? 

Ahh, so they're similar to aggressive! Thank you all!  ;w;
