The article misses the most important point about what happens when wolves are raised like dogs.
The full-grown wolf will be a wonderful and intelligent member of the household right until the master of the house shows some sign of injury. Then your loving pet will try to take control of "the pack".
This is the primary reason that they have to get euthanized. At that point they cannot live in the wild, and they are no longer safe to have in your home.
