I made so many versions of it that I don't remember how it was trained, it should work the same way as the futanari horse ?????, because it has a wide range of furry images it tends to do it without being prompt, if it has a lot of animal parts try to put in the negative prompt.

The futanari_canine_penis, it can be over trained, I recommend using it in 0.7,lower epochs should work fine,
