There’s a very promising new transformation game with a short demo out y’all should check out and support (they’ve got a patreon)- as of now it’s a Ren’py game that will heavily focus on women with anthro fox, donkey, pig, and werewolf forms. A lot of the imagery focuses on them being partially changed, and most importantly the demo does feature the beginnings of the donkey girls transformation.
