To solve this mystery, scientists measured the skulls of 55 wolves and 159 dogs of different breeds in an attempt to calculate the relative brain sizes of wolves and dogs. The results showed that the average brain volume of dogs is about 99.7 cubic centimeters, while the average brain volume of wolves is 131 cubic centimeters.
In other words, the brain of a wolf is more than 30% larger than that of a dog.
In addition, scientists also found that the closer the relationship between dogs and wolves, the smaller the brain capacity. (Husky: Are you clicking on me?)
