Researchers at the University of Portsmouth are delving into how dogs think and communicate, shedding light on the complexities of canine cognition. On a winter's day, a flat-coated retriever named Calisto participated in experiments designed to assess her intelligence, part of a broader investigation into the bond between humans and dogs, which has existed for thousands of years.

According to the Pet Food Manufacturers Association, 33% of households in the UK own a dog. While dogs serve numerous roles, from assisting in detection tasks to being beloved family pets, scientists believe their behaviors can provide insights into human communication.
During the experiment, Amy West, a PhD student at the dog cognition center, presented two flower pots to Calisto, placing a treat under one while leaving the other empty. When prompted, Calisto quickly identified the pot with the sausage. Dr. Juliane Kaminski, a comparative psychology expert at the university, noted that dogs have been domesticated to respond to human gestures, unlike their closest relatives, chimpanzees.
Kaminski highlighted the importance of understanding whether dogs and children interpret gestures in similar ways, which could enhance our understanding of human communication. In a subsequent task, Calisto watched as West hid cheese under one pot and then swapped the positions, testing her grasp of object permanence—the concept that objects continue to exist even when out of sight. Although many dogs struggle with this notion, Calisto successfully chose the correct pot three out of four times, though Kaminski suggested her proximity might have aided her.
Kaminski's research includes studies on Rico, a border collie known for recognizing over 200 object names. Initial observations led Kaminski to think Rico was merely responding to human cues, but further investigation revealed his genuine ability to comprehend language. Kaminski and her team hope to uncover more dogs like Rico through their new initiative, "Finding Rico," though they anticipate identifying only about 50 globally.
It's important to note that while Rico excelled at learning object names, he faced challenges with object permanence, suggesting that canine intelligence encompasses diverse and complex skills. Kaminski explained that while some believe dogs can think like toddlers, others argue they lack flexible reasoning. She concluded that the truth likely lies between these perspectives, and research into canine understanding is still in its early stages.
Additionally, studies have indicated that dogs exhibit more facial expressions when being observed, notably raising their eyebrows, which may enhance their appealing appearance to humans. Kaminski posited that this behavior could reflect an evolutionary selection, as dogs look more infant-like with these expressions, but clarified that it is uncertain whether dogs consciously modify their expressions to elicit specific responses from their owners. As research continues, Kaminski remains focused on unraveling the mysteries of canine intelligence.
