Well done for losing the weight so far. Unfortunately people think that some of the heavy horses are excellent weight carriers but they can't always carry as much as you would think, pull yes but not carry.

To be honest and I really don't mean to offend you but I would say that you would need to lose a bit more. Maybe once you are down to about 15 stone you could look at a heavyweight cob or a Clydesdale or Shire cross. I've had a Shire cross before and he was fab but unfortunately they do tend to cost a lot to look after as you have to pay extra for worming and shoes due to their size.
