I am trying to see if there is anything I can put on Bianca's nose that she won't just lick off, to protect it? I've noticed her nose was dry and flaky and I thought it was maybe diet related, but then I noticed that it is worse on days we go outside for long periods. I think it may be from exposure/sun so I wanted to use a sunscreen. The problem is anything I put on her nose is immediately licked off, and I don't want to use something that she will just remove right away or that might be harmful if ingested. Any suggestions?
