What feature of the wolf's tail distinguishes it from many domestic dogs?

Answer

It hangs straight down or extends outward, never curled

A key physical identifier noted for wild wolves, particularly when distinguishing them from many domestic dog breeds, is the posture of their tail. The wolf’s tail maintains a relatively straight orientation, either hanging directly down or extending outward behind the body. Critically, it is never observed curled up against the back, which is a common characteristic in various domestic canine populations. This straight, bushy tail also plays a significant role in maintaining balance during their characteristic long-distance running and in non-verbal communication within the pack structure.
