[1.12.2] Passive mob/entity with multiple texture variations

[Erfurt]

Hey guys, so I have been working on making a new passive mob/entity, everything works as I want it to. However I would like to use multiple different textures for it. After looking at some of the vanilla code for other mobs, I wasn't able to find anything solid that I could use. So how am I supposed to do this? From the information that I have been able to gather, it seems that vanilla mobs can have variants in a folder for a mob, but how would I do the same thing for my mob?

You can't just say "I wasn't able to find anything solid that I could use". You need to say what you looked at and why you had difficulty. I mean you want this to work like a horse, right? So I assume you looked at EntityHorse and its parent AbstractHorse? After looking at that, what did you try? Or what is your actual question?
