This is a merge of Indigo's SDXL/Pony Model and Nova Animal Pony's Model.

Indigo's model focuses on males. Nova's Animal Pony does realism.

Mix them together and you get: male realism (it does females well, too!)

If the model defaults to generating humans: you can put "human" in the negative prompt. You can also specify fur/scales/feathers and/or increase the strength on the species tag.
For example:
"yellow feathers" or "gray fur", "white scales", "detailed {fur|feathers|scales}"

"(wolf:1.2)"

Adding the Pony score tags may enhance realism on some generations. Not adding them might make the generation look more like a 3D render than realism.
