What do our dogs really think of us?

We love our dogs.

In the 30,000 years humans and dogs have lived together, man’s best friend has only become a more popular and beloved pet. Today, dogs are a fixture in almost 50% of American households.

From the way dogs thump their tails, invade our laps and steal our pillows, it certainly seems like they love us back. But since dogs can’t tell us what’s going on inside their furry heads, can we ever be sure?

Actually, yes. Thanks to recent developments in brain imaging technology, we’re starting to get a better picture of the happenings inside the canine cranium.

That’s right — scientists are actually studying the brains of dogs. And what the studies show is welcome news for all dog owners: Not only do dogs seem to love us back, they actually see us as their family. It turns out that dogs rely on humans more than they do their own kind for affection, protection and everything in between.

The most direct brain-based evidence that dogs are hopelessly devoted to humans comes from a recent neuroimaging study about odor processing in the dog brain. Animal cognition scientists at Emory University trained dogs to lie still in an MRI machine and used fMRI (functional magnetic resonance imaging) to measure their neural responses to the smell of people and dogs, both familiar and unknown. Because dogs navigate the world through their noses, the way they process smell offers a lot of potential insight into social behavior.

The scientists found that dog owners’ aroma actually sparked activation in the “reward center” of their brains, called the caudate nucleus. Of all the wafting smells to take in, dogs actually prioritized the hint of humans over anything or anyone else.

Read the rest at the original article. Delightful study, especially – I guess – because it reassures what humans like me feel goes back to the time when we shared our caves with our dogs. And all the way up to and including our modern dwellings. Especially when it feels like the house and furnishings belong to the dog as much as anyone else.

Well, at least in our house.

Thanks, Mike

    “Dogs hear our words and how we say them” http://www.eurekalert.org/pub_releases/2014-11/cp-dho112014.php Also: “A University of Sussex research project has suggested that man’s best friend can process human speech in rather sophisticated ways. Mammal communication researchers in the School of Psychology tested more than 250 dogs to see how they responded to a set of spoken commands. They found that, like humans, dogs use different parts of the brain to process the verbal components of a familiar sentence and the emotion or intonation of the speaker.” http://www.bbc.com/news/uk-england-sussex-30214426
