Sickle tail
The sickle tail is the single phenotypic characteristic that seems to separate dogs from wolves.[1] Dogs who have tails tend to have an upward curve in the tail, which is called the sickle tail. Wolves' tails, on the other hand, hang straight; this is called the brush tail—similar to that of a fox.
