Manga sauce

I'm looking for a manga/hwa/hua I don't remember well, I followed it for months, it was about Buddhist things

I remember that the protagonist was a wolf who became a human and lived with a clan of dragons, but they were attacked by heaven and he was the only one who survived along with another girl, which is actually the sutra they have to carry. to nirvana.

one of the characters was a pig, another a monk who, long ago, was the one who brought the sutra to the world along with a Dragon that had been turned into a horse.

​

Sorry if it's hard to understand, I'm translating it from Spanish to English
