Anyone have any suggestions on what I can do to make my horse comfortable until the farrier gets here?
Go to the hardware or lawn and garden shop. Look for those soft, flat pads that people kneel on when gardening. Another option are the puzzle-cut pads that people use to cover their garage or workshop floor. Buy a couple of those pads to cover all four feet or just one pad if you're only addressing the front feet.
Have the horse stand on pads, one foot at a time. Trace the hoof outline on the pad with a magic marker. Now cut the pad to create your temporary "horseshoe".
Clean the foot (walls and solar surface) with a wire brush then "paint" the bottom of the foot (frog/sole) with iodine or betadine.
Use duct tape to apply the "horseshoe" to the horses foot. Don't allow the tape to cover the heel bulbs or the soft tissue at the coronary. Keep it on the hoof wall. The hoof wall should be clean and dry to assure the tape will stick.
This protocol will make your horse more comfortable and assist in preventing solar bruising and/or abscessing.
Also, what should I be expecting as far as hoofs being short? Never dealt with this. Are we looking at boots, shoes, or what? I know it is hard to tell with no pics (sorry)....but any insight will be helpful.
If there is enough distal wall to work with, the farrier will probably want to install a "deep seated" set of shoes.
If there isn't enough distal wall to nail up the shoes, the farrier may opt to glue on a set of shoes or may recommend hoof boots. Hoof condition, limb/capsule conformation, environment and cost will be deciding factors.
Tell the BF he should probably keep his day job.
