Well, lets put it this way.
My LOVES fluffy mini babies. he bought a mare...and a stud. Made some babies and sold the stud this past spring.
My vet has seen her, but has never mentioned anything about it. We're getting her teeth floated so I'm going to ask her about it.
On the topic of her hooves, yeppers. I've been in contact with my vet for recommendations and I've called around for the farriers of various breeding facilities. I have quite the list to call and weed out whether or not they do minis.
