I have a mare who has a pink nose that in the past has blistered and bled as well. What I have found that works perfectly is to put zinc oxide on her nose with my right hand every morning while I hand feed her (with the left hand) oats and then I put on her fly mask. She looks forward to this routine every morning and accepts the zinc oxide with no problem. It’s best to get the zinc oxide in the tube with not less than 30% zinc because it holds up the best (not runny) and stays on the longest (usually all day). Hope this helps…it works great for my mare.
