Sorry for the lack of posts lately; I've been caught up with other things. I will restock the queue eventually.

The top of a wolf's head is fairly flat, not rounded or pointed.

The position of a wolf's tail can indicate its emotions or level of dominance. A wolf with its tail raised high is very assertive or aggressive; the higher the tail, the more dominant it is trying to appear. A wolf with its tail tucked in beneath its body is usually displaying submissive behavior or fear, and much like with a raised tail, the degree of tuck indicates the level of fear or submission. A slight tuck may signal casual submission or uncertainty, whereas the tail pressed all the way to the belly may signal extreme fear or appeasement. Of course, the other body language, facial expression, and vocalizations of the individual should also be taken into account when analyzing what a wolf is trying to communicate.

A wolf's tail helps it to balance, especially when moving. The movement of the tail will counter the movement of the body, reducing side-to-side sway on the animal. A wolf will also use its tail as a counter-balance when turning, allowing sharper movements and less energy usage.

A wolf's lower canine teeth are farther forward in the mouth than its upper canine teeth.

While wolves let their tails hang down at rest, they often raise them to be near-horizontal when running.

Wolves have distinct cheek ruffs, that is, tufts of fur that flows off the sides of their faces. This leads to the head looking more diamond shaped, and even larger than it actually is.

Tail-wagging is involved in many wolf behaviors. In addition to the practical back-and-forth movement to help balance when moving, it is also often a social cue. Wolves that wag their tails stiffly, like a pendulum swinging side-to-side, are often doing so out of excitement. Wolves that wag their tails fluidly, with a snake-like movement, are often doing so as part of greeting or play. Excessive wagging can also be a sign of submission, and may cross over with the tail-wagging of greeting.

Wolves have scent glands between the pads of their paws. To spread the scent, they may repeatedly scratch or kick the ground, particularly with their hind paws, and often after urinating or defacating. This is fittingly called scraping or ground scratching. Like many other scent spreading behaviors, this is often used to mark territory, claim something in the area as the wolf's own, or leave an announcement of their presence.

Before a wolf has pups, it will first find or make a den to have them in (or some mix of the two). A mother wolf wants somewhere safe to give birth and to raise the pups for the first few weeks of their lives, while they are still weak and vulnerable. Factors that influence the den site include: distance from the edge of the pack's territory, proximity to water, canopy cover, and surrounding vegetation or terrain that can obscure the den entrance. Many wolf dens are dug out under fallen logs or large rocks, probably because they provide a roof with a strong structure.

Wolf pups and yearlings will lick or stick their snouts in the corners of older wolves' mouthes, which triggers them to regurgitate food for the pups to eat. Wolves will also regurgitate food for a pack member who is pregnant or nursing, and therefore cannot hunt with the rest of the pack. They may also regurgitate food for other adult pack members, but this is significantly less common.

Eye contact (or lack thereof) is part of how wolves communicate. Direct, prolonged eye contact can be a sign of aggression or dominance, whereas pointedly avoiding eye contact is an appeasement behavior, signaling that the wolf does not want to have any trouble. In the most dramatic cases of the latter, the wolf will open its eyes wide and look away so that the white of the eye is visible (this is called "whale eye," especially when referring to dogs). Displays of aggression aren't the only time wolves make eye contact though. Wolves often make eye contact when greeting each other, or any other time they want to assess how the other wolf is feeling by reading their facial expression.

When a wolf's moth is closed, its canine teeth are long enough overlap the gums of the opposite jaw, rather than stopping at the height of the teeth of the lower jaw.

A wolf has a relatively large head in relation to its body.

When a wolf comes across a strong- or unique-smelling object or scent, it may roll in it. This is called scent rolling. We aren't certain of the reason or reasons for this behavior, but some theories are: a) the wolf using the strong scent as olfactory camouflage, using it to cover their own scent so that prey animals don't recognize it as easily, b) the wolf claiming the item as its own by mixing their scents together, or c) the wolf wanting to carry an interesting or useful scent back to its pack members, and convey some information about what it's found.

Sometimes a wolf will jab at a potential food item with its nose and jump back before taking the first bite. It does this to make sure that whatever it is about to eat is dead, or at least unable to fight back or injure the wolf in any way.

The base of a wolf's ears sit on its head at about a 45° angle.
