Wolfren are usually furred with a strong upper body. The length of their fur varies but their coats are always thick, with many hairs per follicle. In addition, most Wolfren tend to grow a fluffy mane, though it's not impossible to find them without one; those with manes definitely have an advantage in the colder climates of Vulcareal. These canines are built to be both bipedal and quadrupedal, though most will default to all fours when speed is of the essence. When standing on their hind legs, they can appear quite large, reaching about six feet or more.
Their ears are always floppy though the length can vary; they can still perk their ears up and pivot them around. The floppiness does, however, slightly obscure their hearing, but they make up for it with a keen sense of smell!
Wolfren always have two protruding teeth, either from their upper jaw or lower jaw, resulting in an overbite or underbite. If removed, these new teeth grow back in their place. This durability coupled with the species' massive jaw strength makes them very powerful hunters, fighters, and just workers in general.
Instead of fingers, Wolfren have large foreclaws and an opposable thumb. Unlike the claws of most other species, theirs are made from a special, incredibly hard material that makes them resistant to all elements. Therefore, if a Wolfren is born with dull claws, they have no means of sharpening them; they must seek out Chuikhas for help in superheating and reshaping their claws. Much like with Gryfons' helmets, Wolfren's claws can go through this process without causing the individual pain.
Tails come in a variety of shapes and sizes, and are clear indicators of how a Wolfren is feeling. It is harder to identify the moods of Wolfren who do not have them.
