We all know that the IQ of puppies is very high, and their IQ is different according to different dog breeds. Generally, the IQ of adult dogs is similar to that of children aged three or four, and that of dogs with high IQ is similar to that of children aged six or seven. It can be seen that the IQ of dogs is still very high. It is often seen in online videos that dogs can help their owners buy soy sauce and even go out to buy food. In fact, the size of the dog's skull and their IQ are innate, but it also needs later training and teaching, just as children can learn more knowledge through learning.

Different breeds of dogs have different IQ. At present, the cleverest is the border collie. The IQ of an adult border collie can reach the IQ of an eight-year-old child, and the average border collie is between two and seven years old. It can be seen that IQ has a lot to do with dog breeds. Shepherd dogs can manage sheep well. A sheepdog can manage hundreds of sheep without losing them. As long as they are responsible for guarding and preventing other animals from attacking, they can be said to be the best helpers in the pasture.

Scientists have proved that human civilization began with eating cooked food, and the IQ has been greatly improved because humans began to use cooked food. The human body needs more energy to digest raw food, which will affect the development of the brain, and so will dogs. In the past hundred years, domestic dogs basically no longer eat raw meat, but feed cooked food through their owners, so that they will have enough energy to promote the development and evolution of their brains.

Dogs are the most loyal partners of human beings, and they can protect their owners regardless of their own lives in times of danger. Their friendliness to human beings is unmatched by other animals, and dogs will have a very strong reaction to human tone. Smart dogs can make reflective understanding through simple words, thus making correct judgments. Many families will keep a pet dog to accompany their children, which can cultivate their love. Smart dogs will learn a lot from their children, which is why they often hear the owner of the border collie vomit, and always feel that the border collie is teasing them and their IQ is despised by the border collie.
