Its a long story but to summarise.. bought by the person I got him off as a yearling, worked with and broken in later on, lent to 'friend' when owner had children etc. owner was told all was good he was happy and healthy by the 'friend'.
Some time later gets told to come get him or he'll be put down because of a rotated pedal bone. Owner goes and gets him and he is totally neglected, skin and bone, feet a mess, teeth a mess etc.
Gets him back to looking somewhat decent and then I bought him :)
