You don't have to use this, but it would definitely make the roleplay more realistic!
A wagging tail is a sign of a wolf being relaxed. If the tail is slightly drooped and the tip is out, it shows an even more relaxed wolf. If the tail is in a drooping / hanging position the wolf is super relaxed.
A tail held up high reflects dominance or confidence.
Before a wolf attacks and while hunting, the tail is stiff and horizontal.
Submission can be in the form of crouching, tail tucking and even the licking of the higher ranking wolf's muzzle. As adults this form of behavior is usually a sign of respect to the higher ranking wolf, the submissive wolf is accepting their place in the pack.
Nuzzling another wolf is generally a sign of affection.
Howling is a way of communication generally to find the location of other wolves.
