Have you ever watched dogs play at a dog park, seemingly smiling, jumping, and pawing all over each other, and wondered, "What do dogs think about?" or "How do dogs think?" Maybe you looked at your dog staring longingly out the window wondering what thoughts are crossing their mind, or chatted with your dog before work, feeling absolutely positive they understood everything you just said. But, does he? Are you simply assuming your dog understands you because their nonverbal communication, like eye contact, and even verbal communications like barking, make it seem as if they really get what you're saying?
Wondering how a dog's brain works is not a new subject. Humans have been pondering this question for centuries. Consider this quote from Jeremy Bentham, which dates all the way back to 1789, "... The question is not, Can they reason? Nor, Can they talk? But, Can they suffer?" All loving dog owners like to think that their furry friend can communicate with them. In fact, many believe that their dogs experience a wide range of emotions and worry about their pet's happiness and emotional well-being. Because of this, pet parents want to believe that dogs communicate, even if there happens to be a language barrier.
While dogs may not speak words in the same language as you, they are able to comprehend the world around them. The key is to understand how their brain works to see what they think and better understand their communication cues.
Do Dogs Think Like Humans?

There are numerous studies of how the human brain processes language, but how do dogs think? Neuroscientists at Eötvös Loránd University in Budapest recently completed a study published in Science in which they scanned the brains of thirteen family dogs with an MRI. While they were in the scanner, the dogs listened to their trainer's voice saying various phrases, such as "well done," which was considered a meaningful phrase, and "as if," a meaningless phrase, both in praising tones and emotionally neutral tones. The findings showed that the meaningful phrases were processed in the left hemisphere of the brain, regardless of intonation, which is similar to human's processing, but the meaningless phrases did not register. "It shows that these words have meaning to dogs," says Attila Andics, a neuroscientist who was a member of the research team.
In this study, intonation did play a role in the dogs’ understanding and was being processed in the right hemisphere of the dogs' brains. For example, speech that resembled praise lit up the reward system area of the brain. The findings of this study indicate that the meaning of phrases and the tone in which they are delivered are processed separately to help dogs identify what specifically was said to them.
