Amid the pandemic, many people have been spending more time at home with their dogs, leading to increased curiosity about their pets' thoughts and feelings. As a researcher in dog cognition, I often wonder what my dogs, Charlie and Cleo, are experiencing during our daily lives together.

With more Americans working from home, many have found themselves sharing personal spaces with their furry companions. This has led to an uptick in pet adoptions as people seek the joy of having dogs in their lives. As a result, I've received questions from both new and seasoned dog owners about their pets’ mental states and overall happiness.

Research on dog cognition can shed light on what dogs think and require to live fulfilling lives.

Dogs possess an extraordinary sense of smell that far exceeds that of humans. While I appreciate the beauty of our walks, my dogs are occupied sniffing the ground, detecting scents from other animals and people that are imperceptible to me. Dogs can smell cancer, explosives, and even COVID-19, demonstrating their remarkable olfactory abilities.

A dog's sense of smell is estimated to be 10,000 to 100,000 times more acute than that of a human. This is due to their having around 300 million olfactory receptors compared to our roughly 6 million. Their olfactory epithelium is also significantly larger, allowing them to process smells in a way we cannot fathom. For perspective, this capability is akin to detecting a teaspoon of sugar in enough water to fill two Olympic-sized swimming pools.

To enhance your dog's happiness, consider taking them on “sniffy walks,” where they can explore at their own pace and gather information about their environment.

Research indicates that dogs share a deep emotional bond with their owners, akin to the attachment between infants and parents. When dogs are separated from their owners, they show signs of distress and eagerly reunite upon their return.

A study discovered that food-deprived dogs often greet their owners before eating. Additionally, when a dog gazes at its owner, both release oxytocin, known as the “cuddle hormone,” reinforcing their emotional connection.

To strengthen your bond with your dog, engage in eye contact, offer physical affection, and even use a playful tone when speaking to them. These actions can enhance their happiness and deepen your relationship.

Understanding your dog's behavior not only satisfies your curiosity but also helps ensure they lead a fulfilling life. Now, I'm off to spend some quality time with Cleo and Charlie, letting them guide me on our next exploration.
