So I've been looking at pictures of pony breeds, and trying to figure out what Duncan could be mixed with. Neither of his parents are registered as anything, but I know that they're definitely not Shetlands.
He's a year and a half old, and roughly 10hh.
Here's his head:
And here he is from the side-- you can see how long his "ankles" are (that's what I call them). And the farrier is scheduled to come, so ignore is long feet. You can also see how he has a slight Roman nose (I love his face )
So, pony experts, what do you think he could be crossed with? I'm hoping he'll top out at about 11hh. That would be awesome.
