Thanks for the help, guys. My dry lot is really quite large because most of my property is heavily wooded, so there is plenty of space. I'm really not looking to take on another nearly full-size equine, so I would not want a 12hh pony as a companion. Whatever I get her needs to be small enough that I can afford to feed it and pasture puff pony with her expensive vet bills, and keep my riding horse boarded. I understand a mini has vet bills, too, and have emergency funds, but on a regular basis, I couldn't afford a third near full size horse. I do not have enough hay or storage space, and can't afford to buy by the bale or substitutes for them. Maybe I should look in to getting her a goat to hang out with.
