I always keep my horses legs on. In the winter i feel they need that extra protection from the mud. Although when you need to go somewhere you have to get the clippers out and do a bit of a tidy up!
this is llewi full clipped with legs left on - did it 2wks ago - you can just see the lines but he's still got quite a fine coat at the moment - he's just a sweaty beast so needed clipping.
