same issue here, what's even more annoying is that the quest doesn't show as completed, or as a current one. the wolf was sleeping at the end of my bed just chilling however -_-
I found the skillbook for the skill, so I've got it at lvl 1.. would really love it if ubisoft fixed the damn quest already =(

also reloading saves wouldn't really work as I did the quest about 20 ingame hours ago -___-

Did the side mission to save the wolf from a basement. Apparently you're supposed to receive the man's best friend skill from it? I do have man's best friend at lvl 1, but that's from finding the skillbook for it.
