Pigs are actually considered the fifth-most intelligent animal in the world—even more intelligent than dogs—and are capable of playing video games with more focus and success than chimps! They also have excellent object-location memory.
7. African Gray Parrots. African Gray Parrots are thought to be one of the most intelligent species on the planet, rivaling even apes. Some researchers have suggested that these parrots have a reasoning ability akin to a three- or four-year-old human child.
Your Grumpy Pup Is a Very Smart Dog — Science Says So
That said, research has been divided on the dog/cat intelligence question, with some studies suggesting dogs are more intelligent than cats because of their social nature, while others found that cats rank higher in abilities, such as long-term memory.
Horses and Dogs are both intelligent animals, but they have different cognitive strengths. Horses excel in areas like navigational intelligence while dogs do better with social intelligence. Neither animal is smarter than the other, that's just what makes them unique!
Chimpanzees. Chimps are our closest relatives in the animal kingdom, so it's unsurprising they display intelligence similar to that of humans. Chimps fashion spears and other tools, display a wide range of emotions, and recognize themselves in a mirror. Chimps can learn sign language to communicate with humans.
Dolphins are often cited as the second smartest animals on Earth due to their relatively high brain-to-body size ratio, the capacity to show emotion, and impressive mimicry of the dumb apes who research them.
Recognizing themselves in a mirror, learning to perform certain behaviors and solve problems faster than other animals are some of the skills of pigs, considered to be one of the smartest species, even more than chimpanzees, dogs or dolphins.
Pigs are gentle creatures with surprising intelligence. Studies have found they're smarter than dogs and even 3-year-old children! In the wild, pigs form small groups that typically include a few sows and their piglets.
Rats are as smart as dogs
And, while rats are much smaller than elephants, they have excellent memories.” American veterinarian and rat advocate Dr Karen Becker states: “Studies also show that rats are surprisingly self-aware, they're ticklish, and they dream just as we do.
Kangaroos showcase a notable level of intelligence, as evidenced by their ability to establish communication with humans to acquire food and employ strategic tactics, such as luring predators into the water for self-defence.
1. Border Collie: A workaholic, this breed is the world's premier sheep herder, prized for its intelligence, extraordinary instinct, and working ability. 2. Poodle: Exceptionally smart and active.
Dogs understand human language better than dolphins.
But are they as intelligent as dolphins? In some areas, no; in others, yes. Dogs did not make the grade on the self-awareness Mirror Test—something dolphins have mastered—and dolphins appear to be better problem solvers.
Few animals are trainable in this way, particularly animals that aren't domesticated. Dogs, for example, can do a great number of things. Bears are believed to be more intelligent than most dogs, but dogs have been domesticated for thousands of years.
Koalas. Koalas are not only extremely cute, they're smart, too! The marsupials know how to listen to their bodies and can dive into a deep sleep for an average of 22 hours a day. Koalas snack on eucalyptus leaves, which aren't high in nutrients—the abundant rest makes this diet possible.
Although chickens have a reputation of not being the smartest birds in the nest, the studies indicate that they are on par with other highly intelligent species such as dogs, chimpanzees, elephants, dolphins and even humans, Marino said.
While intelligence is difficult to quantify in any organism, many studies suggest that dolphins are second only to us humans in smarts. Using brain size as a barometer, dolphins come in second only to humans in brain-to-body size ratio. However, dolphins also excel intelligence-based tests.
Research based on cranial capacity proportionate to body mass and cognitive testing indicates that dolphins are smarter than chimpanzees.
Horses are very social and affectionate animals. They cannot verbalize “I love you” but they can communicate those sentiments through their actions. Not all horses show affection in the same ways though. Here are some things to look for in your horse's behavior to know he loves you.
The average dog's IQ is about 100. Based on the results done to test a dog's IQ, it turned out that dogs, even the average ones, have the IQ same as a 2-years old human.
Dogs often seem more loyal and protective of their owners than horses. One reason for this that according to history, dogs have been domesticated much longer than horses. Dogs will also willingly defend themselves and their “pack” from danger by standing their ground and even attacking.
