What is the symbol on Kakashi's ninja dogs' backs?


Every one of Kakashi's ninja dogs has a symbol on its back that looks like a
face:

**What is this symbol and what is its meaning?**




It's a pretty interesting explanation... In this wiki for
[Ninken](http://naruto.wikia.com/wiki/Ninken) (Ninja dogs):

> They all have a face-shaped design on their backs called **Henohenomoheji**
> (へのへのもへじ) — which is the sound made when all the characters in the face are
> put together. Appropriately enough, children use this design as the face for
> their scarecrows, which is _"kakashi"_ in Japanese.

Basically, if you consider the picture you included:

  * The **eyebrows** are the Hiragana へ (he);
  * The **eyes** are the Hiragana の (no);
  * The **nose** is the Hiragana も (mo);
  * The **mouth** is another へ (he);
  * The **head shape** (kind of distorted) is the Hiragana じ (ji).

So, へのへのもへじ (henohenomoheji). The first "heno" is repeated because you have a
pair of eyes and eyebrows.
