Your canine companion slumbers by your side, but is she dreaming of you? Does she feel guilty about stealing your steak off the kitchen counter and eating it for dinner? What is she trying to say with that annoying bark? Does she like watching tv? After decades of research, neuroscientists have begun to answer such questions, giving us access to the once-secret inner lives of our canine companions and even translating their barks and wags so mere humans can comprehend them. At the forefront of this effort is Stanley Coren, a behaviorist from the University of British Columbia, who draws on decades of research to explore the psychological motivations behind dogs’ everyday behaviors, as well as what science says about their barks, thoughts, and dreams.

Do Dogs experience the Same Emotions as People?

Dogs have the same brain structures that produce emotions in humans. They have the same hormones and undergo the same chemical changes that humans do during emotional states. Dogs even have the hormone oxytocin, which in humans is involved with love and affection. So it seems reasonable to suggest that dogs also have emotions similar to ours. However, it is important not to go overboard: The mind of a dog is roughly equivalent to that of a human who is 2 to 2½ years old. A child that age clearly has emotions, but not all possible emotions, since many emerge later 
in the path to adulthood.

Dogs go through their developmental stages much more quickly than humans do, attaining their full emotional range by the time they are 4 to 6 months old. Much like a human toddler, a dog has the basic emotions: joy, fear, anger, disgust, excitement, contentment, distress, and even love. A dog does not have, and will not develop, more complex emotions, like guilt, pride, contempt, and shame, however.

You might argue that your dog has shown evidence of feeling guilt. In the usual scenario, you come home and your dog starts slinking around and showing discomfort, and you then find his smelly brown deposit on your kitchen floor. It is natural to conclude that the dog’s actions show a sense of guilt about its transgression. However, this is simply the more basic emotion of fear. The dog has learned that when you appear and his droppings are visible on the floor, bad things happen to him. What you see is the dog’s fear of punishment; he will never feel guilt. He will also never feel shame, so feel free to dress him in that ridiculous party costume.

Why Do Dogs Prefer HDTV?

Most dogs show little interest in the average television set because of their visual abilities. In its simplest form, a motion seen on the tv screen is just a changing pattern of light across the retina in our eye. The average person cannot see any flickering above 55 cycles per second (55 Hz). But beagles see flicker rates up to 75 Hz—about 50 percent faster than human rates—suggesting dogs perceive motion better than people do. Television images flicker at about 60 Hz. Since that is above a human’s flicker resolution ability of 55 Hz, the image appears continuous to us and blends smoothly together. Since dogs can resolve flickers at 75 Hz, images on a tv screen probably appears less real and less worthy of attention. However, since high-resolution digital screens are refreshed at a much higher rate, reports are increasingly surfacing of pooches who become very interested in newer technology hdtvs when a nature show contains images of animals moving.
