How Big Is a Dog's Brain?

Answer

To learn how big a dog's brain is, you need to consider the actual species. Some dogs have a larger brain than others. However, in most situations, the standard dog's brain weighs between three and four ounces. Even though these brains are very small, most dogs are smart and are able to learn. By comparison, a human's brain weighs about three pounds. Dogs, for example, can learn 150 or more words and commands with training and are able to read humans well.
