She's a bay tho so I'm not sure if I could find a horse that could possibly produce that with her and also compliment her, but I'll look more into it when I'm more serious about breeding her.
To produce a registered foal, you'd have to find an APHA stallion and the only way to be as close as possible to guaranteed grulla is a homozygous tobiano and homozygous dun because neither tobiano nor dun exist in Thoroughbreds. I'm not trying to sound like a Debby Downer, but you might have to do quite a bit of searching to find a quality stud that compliments your mare and is homozygous for both tobiano and dun. You could find one probably pretty easily..but I can tell you it will most likely be owned by a color breeder that only cares about the color.
Anywayyy. I do love grullos. I have only seen one in person and it was only when I drove past it several times this summer. I know a girl who just bought one, but I doubt I will ever see him other than in pictures.
