Gelding? I could see that. I thought maybe Gildan was some kind of paint, or line of paints.
Yeah, my first thought was autocorrect too, especially for the "Ovarian" bit, but he clearly wouldn't be posting from his phone. I haven't used Microsoft Word in years, does it autocorrect? I thought it just underlined misspellings.
"Gelded Hanovarian Paint Horse"? poor photo but looks like he may have been a paint that greyed out. But Hanovarians don't come in paint, so it might just be a WAG (Wild A$$ Guess) as to what the horse is. He probably asked a friend to post to CL for him and friend fried the spelling.
