My family and I have a 2 year old mini filly that we have had sense she was a weanling. We have always thought that she was a black tobiano, but now she has white hairs mixed with her black hairs near her flank area, and she has white hairs on each side of her tail near the top, but is black in the middle.
This makes me think that there is a possibility that she may actually be a rabicano. I have no actual experience with a rabicano as no one that I know owns one, which is why I am questioning if she is a rabicano or not.
At the moment I can not get any pictures to upload, I am sorry about that. I will try to get the pictures asap.
