I had a really hard time the first time I razored a horse, but it wasn't that I thought it would be harmful to the horse I was afraid I would by nicking them too much. But I can honestly say I am pretty good at not bringing any blood, they stand reasonably still and do not seem to mind at all. I have one that will almost go to sleep while getting groomed, and another tries to give kisses the whole time. I do the muzzle and above the eyes, not the eyelashes. I have to agree with horsefeather that they are there for a reason, it does give a bigger eyed look, but I am not willing to turn their eyes red and irritated just for that little bit of strategy. The razoring does no harm, unless the person is careless and let's them get sunburned, but if I am going to go to all the trouble to get them groomed, polished and in shape, I think I can keep them out of the sun.
