Storm, it happens to me too sometimes that I have what I refer to as "pixel pony brain" not remembering anything. Not even when I check my list at the matchmakerpage
I need to give gray horses more love. I tend to avoid them because they like to make more gray horses, but some of the coats on here are really gorgeous.
I have a short SH she is 14.3. Where is the cutoff between the PON and the SH. I would like to breed her back to a PON and wondering if I use a Stallion that is 13.3 or under will raise the chances of a PON foal?
In all honesty, it's just luck xD You can definitely get a PON from her. I bred a 15 hand SH mare with a 14.2 PON stud and got a PON filly. I got lucky but to better your chances use shorter studs.
