Sounds unlucky, but is certainly linked to some unfavorable conditions. Laminitis is so variable as to the causes, but I did have a recent case that was linked to Cushing's. That horse is doing great. Personally, I rarely encounter abscesses...mostly happens among Barefoot horses or Horses with Flat soles. Proper farrier care and proper nailing goes a long way.

Here is a nice checklist, feel free to take it and pass it around the barn. Click the pic to see the large-size original.
