Unfortunately I don't have a picture of the lump.
But my Grandpa and I have spanish horses pure breed.
One of our males valued around 60k was being exercised and he hit his ankle on a rail.
This caused a huge lump to grow on his foot and unfortunately we were never able to ride him again.. He was a huge beautiful horse and ended up selling him eventually.
Was wondering if anybody had the same experience of their horse hitting their ankle and causing bad problems.
