Zerda by far, but I also like Kits a lot. Both poses of Zerda are so cute and so energetic and they just flow so well to me. Male Kits look a little awkward to me but I kinda like that about them haha. Just not for every wolf.
I like all of the starter breeds + Zerda a lot, but if I had to name one, it would be Jocols. Simply because it the one breed where I don't like one pose a lot more than the other one. The females had to grow on me, but now I like them both.
I like Kits and Zerdas more than I like the other breeds, but I agree with one of the comments, each has their own special thing, although If I had to chose, I don't really like Lupins or Bracchus that much, Bracchus a little bit because LONG good boyos, but yeah not like my favorite favorite breed (The pup pose slaps tho)
