I know how hard it is to find a name. I have a black TWH mare for a month before I found a name for her. But I think it's kinda like dogs- They have their own name, you just have to find it. The black mare was named Arora after a month of thinking but my prize mare RiverBelle (RIP) was named before she was even mine! I was riding her to test her out to see if I liked her, and the name popped into my head. Everyone thought it was a weird name, but it fit her. And now, that name revolves around me everyday. My farm is named after her, and so is one of my business'.
Sorry for the rant, I just get so excited when it comes to naming horses, haha. I have subscribed to this forum so I can keep an eye on Nilla's progress! Excited!! Beautiful girl by-the-way!
