Dogs are a species in the Animal Crossing series. In the real world, dogs are a domesticated animal that are commonly kept as house pets. They share this trait with the cats.
There are twenty dog villagers in the Animal Crossing series, and eight special dog characters, making dogs the species with the most special characters. There are twelve male dog villagers and eight female dog villagers. Of these, seven are lazy, two are jocks, two are cranky, one is smug, three are normal, three are peppy, one is snooty, and one is uchi. Bow, Champagne, Masa, and Megumi are the only dog villagers which have yet to reappear after Doubutsu no Mori e+.
Although the dog villagers appear to be simply generic dogs with floppy ears, special dog characters have appearances based on a specific breed (Isabelle is a Shih Tzu, Booker is a Bulldog, etc.)
