2019-08-06 size of the brain

I saw a very little bog on my way home.

The dog's head is so little.

I had a question at that time.

"Does a dog have different intelligence depending on the size of the brain?"

A dog has absolutely different body size by type.

Maybe a dog probably also has different brain size by type.

I googled the dog's brain.

I knew that there is no difference depending on the size.

The fact also applies to people.

I understood.

However, what is a size of the brain decided by?

I will google the question next time.
