I was stuck between Fang and Skye, but I had to go with Skye. I've never had either of them, but personally, Skye looks a lot sweeter and welcoming, like...a new day, I suppose. XD Hence her name.
I love that Fang is leading in the poll! I haven't met all the wolves, so I hate to pick. But Fang has been my favorite since the day I first played Animal Crossing - he was the first villager I met ever, and I've always loved him!
My first wolf just moved into one of my towns, Kyle. Didn't like what I read about him. I'm on a roll of getting a bunch of villagers I really don't care for. I'll probably let him go as soon as he asks.
My favorite is definitely Wolfgang, though I honestly think Fang is cuter. I'm not actually sure why, but I really adore him. I've had the same exact Wolfgang since I first started New Leaf and I move him in every time I reset my town. In my current town I spent a day resetting to move him in next to me. If he ever moves out by accident I'll have a minor crisis. And then get someone to hold him and move him right back in.
