Its tough finding good media, almost anything pre 2000 is out because of some sort of bigotry and even after that it gets iffy sometimes, and if you filter for copaganda, zoo propaganda, agri propaganda and corporate propaganda there is not a lot left...
I was going to ask about your home language, as dogs definitely do not "wa" in the US 😹 I love those differences.
Edit: Also, I think of German children's stories as being very bloody: kids get maimed, and the world is generally dangerous. Is that still present at all, or am I out of date by 100+ years?
the latter lol it's just been bog-standard racism the past century. There's quite the movement to create inclusive childrens books though, to normalize different family structures and cultures right from the start, but animal books for vegans are still quite sparse.
edit: there's one book where spousal abuse is played for laughs a couple times though, by a very popular author too, extremely weird shit
