Wolf Puppies Are Adorable. Then Comes the Call of the Wild.

As close as wolf and dog are — some scientists classify them as the same species — there are differences. Physically, wolves’ jaws are more powerful. They breed only once a year, not twice, as dogs do. And behaviorally, wolf handlers say, their predatory instincts are easily triggered compared to those of dogs. They are more independent and possessive of food or other items. Much research suggests they take more care of their young. And they never get close to that Labrador retriever I-love-all-humans level of friendliness. As much as popular dog trainers and pet food makers promote the inner wolf in our dogs, they are not the same.

Dog puppies will quickly attach to any human within reach. Even street dogs that have had some contact with people at the right time may still be friendly.

Some recent research has suggested that dog friendliness may be the result of something similar to Williams syndrome, a genetic disorder in humans that causes hyper-sociability, among other symptoms. People with the syndrome seem friendly to everyone, without the usual limits.

As I was emphatically told in a training session before going into an enclosure with adult wolves, the one thing you definitely do not do is look them in the eye.

whether a delay in social development in a dog’s early life could explain the difference between wolves and dogs

That’s very important, because both wolves and dogs go through a critical period as puppies when they explore the world and learn who their friends and family are.

With wolves, that time is thought to start at about two weeks, when the wolves are deaf and blind. Scent is everything.

In dogs, it starts at about four weeks, when they can see, smell and hear. Dr. Lord thinks this shift in development, allowing dogs to use all their senses, might be key to their greater ability to connect with human beings.

Perhaps with more senses in action, they are more able to generalize from tolerating individual humans with a specific scent to tolerating humans in general with a scent, sight and sound profile.

When the critical period ends, wolves, and to a lesser extent dogs, experience something like the onset of stranger anxiety in human babies, when people outside of the family suddenly become scary.

Wolf Puppies Are Adorable. Then Comes the Call of the Wild. - The New York Times
No one will run to make one of these wolves chase him for fun. No one will pretend to chase the wolf. Every experienced wolf caretaker will stay alert. Because if there’s one thing all wolf and dog specialists I’ve talked to over the years agree on, it is this: No matter how you raise a wolf, you can’t turn it into a dog.

And behaviorally, wolf handlers say, their predatory instincts are easily triggered compared to those of dogs. They are more independent and possessive of food or other items. Much research suggests they take more care of their young. And they never get close to that Labrador retriever “I-love-all-humans” level of friendliness. As much as popular dog trainers and pet food makers promote the inner wolf in our dogs, they are not the same.

Even with fur, teeth and claws, the pups were still hungry and helpless, and I couldn’t help but remember holding my own children when they took a bottle. I suspect that tiger kittens and the young of wolverines are equally irresistible. It’s a mammal thing.
