Question:

I've bought a new horse, can I change its stats?

Answer:

No! The only things that may be changed are the castration of stallions and the disciplines a horse competes in. However, before doing either of these things, it is a good idea to check with the person you bought the horse from, in case they have a sales clause restricting these things. As a note, though, if a horse is accidentally registered in the MHR with an impossible colour or obviously erronous information, correction will be permitted.
