Knowing that temperament is inherited, be sure to buy your Schipperke from a reputable breeder, someone who has taken the time to breed the very best dogs, who has learned as much as they can, know what problems you might have to deal with, and are not only interested in money. Be sure to meet the dam and a few of the Breeder's other dogs as well. Be a responsible dog owner. Train and socialize your puppy from an early age to be a good citizen and cherished member of your family. Just as many Schipperkes are sweet, easy and brilliant, they may also be independent, strong willed and stubborn.
Every dog is an individual, and temperaments do vary.
Schipperkes are very much influenced by their environment. With consistent training, these bad traits can be broken before they become habits. If you have not raised a dog before, get the help of a local dog training facility. Like any other breed of dog, an undisciplined Schipperke is like a spoiled child. Schipperkes are little black bundles of energy.
