The domestic dog (Canis familiaris) has been used by creationists as an example of a creature showing great variability in a short time and as an example of how to account for the variation in living beings (including humans), since the Flood. The spectacular diversity of the domestic dog species occurs not only in size but also in shape. This variability excludes the morphological differences from other wild canids, except wolf-like canids (gray wolf, coyote and jackal).
