Overall the whole series is very, very bloody. There isn't an episode without fighting or blood.

A lot of bloody violence throughout the entire series. Characters/Dogs are attacking each other, moderate blood is always shown.

It is more gory then ginga nagareboshi gin but not more bloody but it is still worst bc of the gore and on scene gore so it is not recommended for people under 12. There is a scene where dogs shove their mouths inside a big monster dogs chest much, much blood and gore, it's detailed and you see limbs fly of when they rip limps of but only fast so it's easy to miss.

"Damn", "Bastard", "Hell" and "Idiot" are the most common curse words in the series.

In Episode 9 "F**k you" is said once

"Asshole", "Goddamn", and "Shit" are used several times.

A couple uses of "crap", "piss" and "fuck".

It doesn't say the worst words but they say words like: shit, bitch, bitching, bastard and asshole so much so it's severe and there is also some uses of: Fuck, Fucked up and Fuck you.

There is 0 uses of drugs, alcohol, smoking.

In Episode 3 there are dead dogs lying around on the ground

There is no episode without violence or fighting so it's severe with fighting and intense moments and bloody too.
