I spoke with my vet today who laid out a plan of action:
1) treat the infection - hydrogen peroxide and apple cider vinegar (these will sting)
2) identify any underlying pathology in the heel region.
3) correct hoof balance so that Candy starts landing heel first rather than toe first.
Interesting protocol approach. Reminiscent of the adage, "putting the horse before the cart".
I'll play the devil's advocate as an educational exercise.
Besides suggesting there is a hoof "balance" problem (there is), did the vet explain why
there is a hoof balance problem, how the imbalance manifests, and how it should be resolved?
Does the veterinarian see the "underlying pathology" as unrelated to the "hoof balance" problem?
Did the trim resolve the "toe first landing" associated with the imbalanced hoof?
Should all horses always land heel first?
There is an etiology to pathological diagnostics. It's a "chicken or the egg" puzzle that leads us to correct protocol.
I also purchased some No Thrush today! From what I've read it seems to be a goer - Candy also let me drag cotton tips soaked in iodine through the cracks.
From what you've read in this thread, a product that delivers low solubility, bactericidal levels of antibiotic "seems to be a goer" for a horse living in chronic wet environs.
the vet wants me to keep going with iodine gauze and bandages so I might invest in some boots she can wear in the paddock to try and keep the hooves dry (or stable if I can get one).
Wrapping an imbalanced, distorted, contracted, shearing, bacterial/fungal infected foot in a largely anaerobic rubber container that will leak, increase breakover length and move the base of support even further posterior the limb axis is... an interesting approach.
The farrier shaved the frog back a bit and actually said he couldn't see thrush and that the frog looked quite healthy underneath?
I find these to be helpful.
Cases he has seen horses with thrush have the foot bleeding and the frog red raw =\ anyway... have a look and see what you think (her hooves are no where near ideal)
I have little doubt that "cases he has seen horses with thrush have the foot bleeding and the frog red raw
". Those are certainly good indicators!
Thank you for sharing your case.
