Sawsbuck, like its pre-evolution, resembles a fully grown deer with antlers no matter what gender it is, like reindeer (or caribou). Sawsbuck changes not its fur color, unlike Deerling, but rather changes the style of its antlers. In the spring flowers adorn them, in the summer, leaves cluster on them like trees, in fall the leaves become orange, and in winter its antlers become completely white and it gathers drifts of "snow" around its neck and hooves. The spots on its back also change colors with the seasons: pink in spring, green in summer, orange in fall, and white in winter.
Its appearance shares a model with the Pokémon Stantler from Generation II.
