/jp/ - Otaku Culture

Hi there, i have a little doubt i hope someone that knows japanese could resolve.

I know that Inu in japanese as dog would be wrote as 犬 , but i want the writing for cur, mongrel, and translate indicates that it would be 雑種 or 駄犬, the last could be verbalized as Daken. I'm wondering if there is a term that could be verbalized as Inu by that meaning.

(the image is related, i wanna print a shirt with Gilgamesh, as that is a recurring insult that he tends to say.)
