Have you ever wondered, like me, how their brain works in such a small skull, how they perceive dangers, and how they alert their owners? How big is a Shih Tzu’s brain? Of course, you thought about it!

The cephalic density of these dogs is very high, and their brains, which weigh 70-80 grams, are well-developed. Their memory is very strong. Research shows these small breed dogs always remember past events and bad behaviors.

These small breed dogs have a compact skull and brains compared to other breeds, but nature has placed receptors in their brains that are present in different dogs. They detect threats and enemies in exactly the same way as wild dogs, and this feature makes this furry fellow distinctive.

Flat-face dogs are very loyal, affectionate, and loving, as all their body parts are very small. Similarly, their brain is 70 to 80 grams, which is very small compared to other breeds. But yes, when it comes to intelligence, these dogs are very intelligent and remember things, so here are some interesting facts about the size of a dog’s brain!

Brain weight and volume:

Intelligence never depends on the weight or volume of the brain; it is a genetic factor that every dog ​​inherits from its ancestors.

  • Brain weight: 70-80 grams (2.5-3 oz)
  • Brain volume: (3.3-4 cubic inches)

Naturally, these dogs’ brains are smaller than those of other breeds, but this does not mean that they are behind in intelligence. These dogs are fully intelligent and have excellent understanding.

I love these small-breed dogs because of their beautiful, shiny eyes, flat faces, and small heads. They are very fun to cuddle. Cranial capacity means the space where the brain fits.

But these dogs still need to catch up in any field!
