There is some variation in brain size among different Dog Breeds, but that is mostly due to variation in body size. W. Tecumseh Fitch's 2010 book "The Evolution of Language" explains that, in general, larger animals have larger brains -- you couldn't very well encase a humpback whale's 10-pound brain in your skull. But if you're comparing brain size relative to body size, as the breed's body size gets smaller, dog brain size doesn't necessarily shrink in exact proportion. Smaller dogs tend to have brains that seem huge in proportion to their bodies when compared to the brain/body ratio of larger dogs.
25-27 in. tall 90-130 lbs. live 10-12 yrs.
The average size of a donkey's brain is comparable to a human. The donkey's brain is between 50 and 75 percent of the size of the human brain.
It is one-third the size of a human brain.
The average brain size of a moose is around 423 grams, which is relatively small compared to its body size. However, moose have adapted well to their environment despite their smaller brain size.
The average brain size of Australopithecines was around 400-500 cubic centimeters, which is smaller than modern humans. This smaller brain size is consistent with their more primitive cognitive abilities and behavior.
Between the ages of 10-12 the average size of a male brain is 1,440 grams and the average size of a female brain is 1,260 grams. The size of a nine year olds brain is only slightly smaller.
The average brain size of a raven is about 15% of its body weight, making it relatively large compared to other bird species. Ravencorvids are known for their high intelligence and problem-solving abilities, which are supported by their larger brain size.
The average human brain weighs three pounds (1.36 kilograms). The average female brain capacity is 79.3 cubic inches, slightly smaller than the male brain of 88.5 cubic inches. The largest human brains may be twice those of average size, but size has no relevance to brain performance.
The average size of a whale's brain is larger than most other marine mammals.
The average Neanderthal brain size was about 1,600 cc, which is slightly larger than the average modern human brain size of around 1,400 cc. This suggests that Neanderthals had relatively large brains compared to their body size.
8-13 in the first litter and English mastiffs are pregnant for about 3-4 months(93-124).
