We rescued a 3yo mini mare that had only seen a farrier once in her life, and had been left in a muddy paddock. She had thrush in all four hooves because of this and I treated it with Iodine sprayed directly onto the bottoms of the hooves, then left her to stand on concrete until the iodine dried to her hooves.. Did that twice a day and in a week it was gone.
My gelding is prone to abcesses, popped 3 last winter *head desk*
It can be caused (as far as I'm aware) from soft hooves and a foreign object becoming lodged inside the hoof, causing the infection there while trying to get the foreign object out. Eg if a nail pokes a hole in a hoof or something. Or a stone bruise can turn to an abscess too
My boy popped 3 consecutively after using a different farrier, not sure if that coincidence or not but yeah.
I soaked in epsom salts and bandaged with poultice (a hoof is the most awkward thing to bandage
) that kept it out of the mud while it was healing too.
The 3rd and last time, I had my normal farrier come out and he dug the abscess out, since then, no more problems. *crosses fingers*
