When I first met Casanova a month or so ago, he was a lot lighter than he is now, but I'm thinking it's either just the change in weather/sun exposure or his breeding, as his dam is black and his sire was a very dark bay. When I first noticed the patch, I didn't think much of it, but now that he's darkening up, this weird little patch isn't! Plus the white fading around it is a little strange.
Anybody have any ideas, or maybe just a birth mark?
My horse has a white mark on her Girth part, but that's a scar I believe from the trainer when the girth rubbed her. I didn't really like that trainer he didn't do a very good job with her so we had to take her to another which did a whole lot of a better job. But that white mark does look cool though on her though.
