Bark at the moon."
In almost any work of fiction that features wolves, werewolves, or coyotes, the canine beasts will almost always be showing howling to the moon at night. On occasion this trope is applied to domestic dogs as well as their wild counterparts.
The howl at the moon is often used to show the power and mystery of the wolves. It also strays into a case of not doing the research because one, wolves howl to communicate, and two, wolves howl just as much during the day as at night.
This trope is often combined with Clifftop Caterwauling to provide atmosphere to a scene. Bonus points if the wolf is silhouetted against the moon.
If the howler is a werewolf, this usually occurs right after they transform.
Other creatures are occasionally shown howling at the moon, but wolves and werewolves are by far the most common.
- The wolf characters from Wolf's Rain are actually invigorated during a full moon. It doesn't necessarily make them stronger or anything, but they feel tremendous joy and energy just seeing it in the sky. Joyous enough to want to howl at it.
- Vampire Hunter D: Bloodlust does the werewolf version, with the Wolf Man howling in front of the full moon after he transforms. With a maw that grows from his stomach!
- In Magical Girl Lyrical Nanoha, the first time we see Arf transform was during the eve of a full moon in the first season. Naturally, this trope was required. In fact, it was the only time we've ever seen one of the wolf familiars howl in the series.
- In Spice and Wolf Holo the Wisewolf is introduced howling at the moon; a pretty powerful scene, as though she is in a human form, the howl is definitely that of a wolf.

- In The Legend of Zelda: Ocarina of Time, whenever the sun sets and the moon rises, a wolf howl is heard.
- The fight against Touhou's resident werewolf (naturally) takes place during a full moon, and involves howling. Lots of howling.
