狗狗颜文字U・x・U：种类、符号技巧与全球传播

1. 狗狗颜文字的符号构成——鼻子、舌头和耳朵技巧

`U・x・U` is the archetypal dog kaomoji: U characters on both sides represent the dog's round ears, while the central x represents the nose (or closed eyes). In (ᵔᴥᵔ), ᵔ represents eyes (a "raised-eyebrow expression") and ᴥ represents the characteristic Y-shaped nose and mouth of dogs. The character ᴥ (U+1D25) is precisely a symbolic rendering of the Y-shaped structure of a dog's nose.

To express tongue in dog kaomoji, ε or ω represents the tongue's curve, creating happy tongue-out expressions like (っ≧ω≦)っ. Floppy-eared dogs use づ or ( for ears, sometimes representing friendly nuzzling actions like (づ｡◕‿‿◕｡)づ.

Breed-conscious variations also exist. ≧∇≦ (excited Shiba face), variants of (=^ω^=) evoking husky blue eyes, (•̀ᴗ•́)و evoking the large ears of a chihuahua.
