Thanks for giving us an update. Glad that things seem to be moving in a better direction for Princess. Will be on the lookout for the latest xrays. Were any done after all the trimming and clogs were applied? It's a good thing that the vet took samples of the infection to culture to make sure it is being addressed with the correct medications.
Just a few thoughts for you to ponder.
How long is she supposed to be on the Isoxsuprine? It has been found to not be very effective when used orally in horses. The J-herb you were using(?) has much better vaso-dilating properties. IF she is on J-herb, shouldn't use it along with Previcox. What is the actual milligrams of the Previcox pill you are using half of?
Nothing applied to the sole will get into her blood to help infection as there is no blood supply anywhere near that area. All the blood vessels are tightly hugging the coffin bone and in the digital cushion. If needed, Lower Limb Perfusion would be one thing that could be done. Another is using sterile maggots.
As far as her diet is concerned, I thought Princess was on a mineral balanced diet? If so, then she has no need for any extra protein. Unfortunately, most vets do not understand that the amount of protein needed is not based on the percent protein of the feeds but on the actual amount in grams that is being ingested. In an IR horse, excess protein can be a lamintis trigger so not a situation of "more can't hurt".
Sue, with your care Princess will outlive most of us. She is indeed a "Princess" and so incredibly lucky to have you as her person.
