This is a friend's elderly pony they asked me to trim for them since I've done a short course on trimming. I've rarely encountered hooves like this though so I'm wanting some other opinions before I do anything.
For some background, she's obviously had laminitis in the past. The owner can't afford xrays at the moment to see what the pedal bone is doing (which is why I'm partly wary about cutting too much off). I've done some *very* basic trims on her in the past just to keep the toes from curling and the heel from underruning and they're looking a LOT better than when I met her.
Apologies for the poor pictures. This was the most solid flat ground on the property. I didn't have my tools with me either so I just had to clean the hooves with a basic cheap knife.
