I also have a sensitive thin-walled TB (soles, not so much). The fix for him was thinner nails and no toe nails.
Thanks for all the suggestions - I did buy Durasole so I will give that a shot, and I will talk to my farrier about smaller nails. I think he was so fixated on keeping the shoes on in the past that he may have been a bit aggressive with the nails.
I do wonder how much the thrush and chronic dampness contributed to him being extra sore this last cycle.
For anyone that has used the equipack pads - did your farrier apply them or did you?
Today he was running and romping and very happy to not be on a trailer heading to a vet again. Unrelated to his foot problems but I can’t believe how quickly his chest wound has healed.
Equipak will stay in better if your farrier applies the mesh at time of shoeing and then pours it in. But you can buy the applicator gun and product yourself and apply it right after shoeing in a clean and dry foot, and in my experience will stay in decently well without the mesh.
