Stoutland is a canine Pokémon with a talent for rescuing people lost at sea or in the mountains. On its face, it has cream-colored fur that forms voluminous, white-tipped plumes and a three-pointed crest. The plumes are so long that they run the length of its body and bunch close to it. It has tufty, pointed ears with dark blue insides, a black nose surrounded by short black whiskers, and small eyes that are nearly hidden behind its facial fur. Its body is covered with shaggy fur that is dark blue along the back and grayish-blue toward the legs. Its face and paws are light brown, and each paw has three toes with white claws. Blue paw pads can also be seen on each paw in Pokédex 3D Pro.

Stoutland has an intelligent, good-natured, valiant, and trustworthy disposition, being a partner of choice for many. Its fur is thick enough to protect itself and others against freezing temperatures. Stoutland found in Alola look fairly uncomfortable, however. Stoutland enjoys spending time with humans and can warm up to them in just three days. It is known to be very proud of its impressive mustache, the reason being due to its length determining Stoutland's social status among its species.
