I found an article online that began to discuss why dogs are truly “man’s best friend” and it was definitely interesting. At Emory University, dogs were trained to stay still in MRI machines so that their brains could be scanned. The researches then used fMRIs, functional magnetic resonance imaging, to measure how their brains respond to different smells.
When reviewing the results, it turned out that when a dog smelled the scent of its owner the caudate nucleus had heightened activity. The caudate nucleus is also referred to as the reward system because it is included in the area of the brain that is associated with finding something pleasurable. It was also found that not only can dogs recognize their owner’s voice, but they can also recognize the changes in tone. It is wired in them to know what they know and act how they do. Dogs think of their caretakers as parents and will go to them when something is wrong with them or their caretaker.

It wasn’t surprising to learn this information but I found it very pleasant and warming. Connection between species is something that can be found in many different ways but the bond between human and dog is truly something special.
