Here's why:
* Different species: Chihuahuas are dogs, while gorillas are primates. They have different genetic makeup and fur types.
* Fur density and length: Gorillas have thick, dense fur that covers their entire body. Chihuahuas have short, fine hair, which can vary in length depending on their coat type.
* Body size: Gorillas are significantly larger than chihuahuas, so even if a chihuahua had the same type of fur as a gorilla, it wouldn't look as furry because of the smaller size.
It's important to remember that comparing the fur of different species can be misleading, as they have different purposes and evolutionary adaptations.
