** The nine-tailed fox, who was quite large when he was going around rampaging. It's interesting to wonder how large he actually is now that he's sealed inside Naruto. The one-tailed tanuki too because although tanukis resemble raccoons greatly, they're actually dogs.

* ''VideoGame/HalfLife2'': An honourable mention for [[ADogNamedDog Dog]], Alyx Vance's enormous robotic pet that she's apparently owned since she was a child.

* In ''Webcomic/GunnerkriggCourt'', Reynardine's true form is that of a large fox, and Ysengrin is an even larger wolf. But it is Coyote himself who can [[ShapeShifting become]] [[http://www.gunnerkrigg.com/archive_page.php?comicID=286 truly massive,]] towering over even Ysengrim.
