Dominance, Food/Predatory
Hackles are a good indicator of the animal’s mood. Raised hackles tend to make the wolf look larger than it actually is and indicates the degree of aggressive arousal. Usually, the farther down the back the hair is raised, the more aroused the animal is. In the most extreme cases, even the tail fur is puffed up (H1234). Although rare, it is possible for a wolf to raise hackles out of sequence, such as neck and rump (H13).
