He's a cutie alright! But I have a bit of a soft spot for awkward ponies
I totally agree with the above posts-
He needs quite a bit of muscle, especially along his topline. He also has a bit of a 'hay belly' which is making his neck look even less developed than it probably is (just not proportionate!)
Again, some hill work, long trotting and work on building neck muscle would do this horse wonders.
That being said, he looks like a total sweetheart!
You're very lucky to have such a tolerant friend :)
