interesting... found this post by the owner of the skinnies:

"My vet sees alot of overfed horses as well as the underfed. There is such a thing as killing them with kindness. Causes problems like founder, navicular, etc."

THATS a great excuse for them looking like that. Sounds like it might be time for a new vet.
A great deal of intelligence can be invested in ignorance when the need for illusion is deep.
