Dog intelligence

Dog intelligence, also known as dog cognition, is how dogs learn, remember, and think. Dogs learn from the world around them, remember what they learn, and use it to solve new problems. This helps them understand and interact with their environment and the people they live with.

Research has shown that dogs have many skills that show they are intelligent. They have great memory and can understand human actions, like gestures and pointing. Dogs also follow voice commands, showing they understand what people are saying.

Dogs can even think about what others are thinking, known as having a theory of mind. For example, they might act in ways that suggest they understand how others feel. They also show self-awareness by recognizing their own smell, which is like passing a test to see if they know themselves. These abilities make dogs very smart and able to connect well with humans.

Evolutionary perspective

Dogs have been used in many studies about how animals think, learn, and remember. Scientists have found that dogs have special skills that help them understand humans, like reading gestures and following commands. These skills are similar to those of young children and might be an example of convergent evolution, where different species develop similar abilities.

Because dogs have lived with humans for thousands of years, they have learned to respond to human social cues and understand words. Some studies show that domestic dogs may have lost certain problem-solving skills compared to their wild relatives, like dingoes. Research also suggests that dogs may have changes in their brain cells that help them learn and remember better. Most studies focus on pet dogs in homes, and dogs from other places might think differently.

Studies history

The first test to measure dog intelligence was created in 1976. This test looked at memory, speed, and how well dogs solve problems. It also saw how dogs deal with new situations and tricky feelings. The test was done with 100 dogs to set standards for different breeds.

Later, Stanley Coren used answers from dog judges to rank dog breeds by intelligence. He shared these results in his 1994 book, The Intelligence of Dogs.

Perception

Perception is how dogs learn about the world using their senses. Dogs are very good at smelling things. They can also see, hear, taste, and feel touch. They might even sense the Earth's magnetic field. Some scientists think dogs can tell time by noticing changes in smells in the air.

Awareness

Dogs can understand that things still exist even when they are hidden. This skill is called object permanence. Dogs learn this skill in steps, just like human babies. By 8 weeks old, dogs can follow an object even when it goes behind screens.

Studies show that dogs can recognize other dogs, no matter how big or small they are. Dogs can also tell dogs apart from other animals. Research using special brain scans has found that dogs can understand human voices. Dogs can also feel the size and movement of their own bodies.

Social cognition

Dogs can learn by watching others, not just by being taught. They watch what their friends are doing and change their actions if the other dog is not looking. Puppies learn fast by copying older dogs.

Dogs are good at understanding people. They can follow gestures like pointing and understand voice commands. In tests, dogs can find where a treat is hidden just by seeing a person point or look in a certain direction. They do this better than some other animals, like chimpanzees and wolves. This skill helps dogs work well with people in many tasks.

Memory

Dogs have great memory skills! They can remember past events and even understand what humans are saying.

For example, some dogs can learn the names of objects and pick them out from a group just by hearing their names. One dog named Betsy, a Border Collie, knew over 345 words and could match objects with photos she had never seen before.

Another dog, Rico, could learn new words quickly. He could understand simple phrases like “fetch the sock” by knowing the meaning of each word. These skills show how smart dogs can be!

Emotions

Studies show that dogs may feel emotions such as jealousy and anticipation. But we need to look at their behaviors carefully.

For example, a Siberian Husky looked guilty when its owner came home to find shredded newspapers. But it looked the same way even when the owner shredded the papers himself. This shows the dog was waiting for a scolding, not feeling guilty like humans.

Researchers study dogs’ emotions using special cognitive tests, called cognitive bias test. Dogs cannot verbalize their feelings. These tests help scientists learn about a dog’s mood. Dogs with separation anxiety may seem more negative, but treatment can help. Dogs can also tell the difference between happy and sad human faces and look at the right side of a face, just like people do. This is a special trait among non-primate animals.

Problem solving

Dogs can solve problems in clever ways. Some dogs have learned to use robots to get food. Others have even learned to ride public transport to reach places they want to go. For example, a dog named Eclipse in Seattle sometimes took the bus to the dog park before his owner arrived.

Studies show that some animals, like dingoes, can be better at solving certain puzzles than typical house dogs. When faced with a tricky problem, dogs often look to humans for help, showing they understand they can get support from people.

Learning by inference

Dogs can learn by making guesses, just like children. They can teach themselves new behaviors by watching and interacting with other dogs. In a study, dogs saw two bowls, one with a treat. After watching the empty bowl lifted and placed down several times, some dogs guessed correctly which bowl had the treat more often.

Theory of mind

Further information: Dog behavior and Theory of mind

Theory of mind is the ability to understand that others have their own thoughts and feelings, just like we do. Some studies suggest that dogs may have a basic form of this ability. For example, dogs might hide food when someone else isn’t looking, which could show they understand that others can’t see what they’re doing. Dogs also notice what objects a person is looking for and can point out the right items, showing they can guess what another person needs or wants. This means dogs might have a simple way of understanding other people’s minds.

Tool use

Dogs can learn to follow special commands, like driving cars. This shows how well they can learn and understand tasks that help them work with humans.
