Are they naturally tail-less?
In general, the Schipperke is considered to be a dog with a tail. Usually the pups are born with tails that are docked at the age of 3 or 4 days. Within a given litter, the pups can be born with a full tail, a half tail (or stub), or a nub. The tail-less silhouette is a requirement of the breed standard for showing.
