my favourite are goldie, daisy, and cookie! i think the dogs are all underrated, id say those three are pretty popular. i just got shep in my new town and i think hes pretty cute, and very underrated!
Walker. I had him in CF and he was so nice and sweet. He's like Marcel's sane older brother or something. I almost never hear about him these days, is it because people think he looks boring? idk.
Honestly I had Walker in my town when I started it and he was around for a while until he moved unexpectedly I wasn't a super big fan of him at the time but I was kind of sad when he moved out because he gave me his picture and everything. I wouldn't mind having him in my town again, he definitely grew on me. But I would have to say most of the dogs are underrated, they're all pretty cute but they aren't popular.
I had Biskit but he moved (naughty Biskit!). Shep and Cherry are currently in my main town and I enjoy them both. Bones moved in not long ago and he's pretty neat too, but I have this weird fascination with Marcel. Must...have...Marcel.
I vote for Biskit overall. I adore him. And I'm glad I selected him to be my one Lazy villager in my villager pictures-themed town ACNLpics.
I do want to single out Butch as well. I think he has the most realistic design of all the dog villagers in "Animal Crossing: New Leaf." Butch is exceptional in this way just as Molly is for the ducks.
I have Walker currently. He's quite a cutie, I'll admit, even if he was a random move-in from someone's void! I'm really looking forward to picking up Marcel sometime soon though. His theme would be perfect for my town, and he looks darling!
