The Wolf Hybrid, or Wolfdog, results from the crossing of a domestic dog with a wolf. The genetic makeup of the offspring can be quite random, which means their behavior is unpredictable. Individual animals may have behavioral characteristics that are like those of the wolf, while others behave more like domestic dogs. It is thought that the aggressive dog behavior shown by the wolf hybrid is predatory.
