Ask a Zookeeper: Wolves vs. Dogs


As many of you know, I am the Zookeeper-in-Residence on Jobstr.com--a website where "you can ask people anything about their jobs and answer questions about yours." I reprint one of my favorite "Ask a Zookeeper" questions on my blog every Tuesday, and you can ask your very own question HERE!

Here is this week's question:

Q. Why are wolves so vicious while dogs are so docile? Aren't they pretty closely related? -circle gets the square

A. Hi circle! The answer lies in the domestication process that transformed gray wolves into dogs. This process began between 15,000 and 30,000 years ago, when early man began interacting with and taming wild wolves. Not all wolves were suited for this, so only the most "sociable" and "approachable" animals were tamed. These wolves bred with other "man-friendly" wolves, and their offspring grew up even more comfortable around man.

As each generation passed, the fear of man gradually left these wolves. And as each generation passed, the wolves' anatomy and physiology began changing. Humans who wanted strong animals to pull their sleds selectively bred their strongest animals together. Humans who wanted fast animals to help them hunt selectively bred their fastest animals together. Eventually, the wolves had changed so much that they weren't even really wolves anymore. That's when they first became dogs. (And that's why there's so much variation between breeds today!)

To answer your question, I would argue that wolves aren't actually "vicious" creatures; they are just wild animals that are guided by instinct and strength and prowess. Their natural fear of man is what makes them appear vicious to us.

Dogs, on the other hand, have been bred and raised among humans for so long that they view our relationship with them as natural. Their instinct to fear us has been absent for many thousands of years, so they are born with a clean slate against us. It is up to us to ensure we live up to their trust.

Awe, thanks, Charlie! Lots of very specialized knowledge about a tiny, tiny portion of the world. I would kick ass in Jeopardy, but only if the only categories were strictly Life Science!

Well, this answers my question as to whether or not I should ever attempt to raise my own pack of wolves... YES! Just kidding. But seriously, I still want to. Who needs a home security system when you have wolves??
