Injury Medicine for a boo boo?

If it's tiny just clean it with some water or safe antiseptic (chlorhex or diluted betadine) and I wouldn't bother putting anything on it. It should heal fine. Neosporin can be harmful if ingested and being on the nose, it's almost sure to be ingested while grooming.

Sometimes the start of a fungal infection can look like a little injury of some kind- especially on the nose. If it doesn't seem to be healing or grows in size you might want to look into treating for fungus.

Well I went out for a couple hours and it was there. It isn't like this has grown overnight - it was just there within 2 hours.

Hi,

I have a similar situation. My wife and I adopted two new piggies yesterday (females ~3 months) and it appears they had a bit of a squabble in the night. This morning one piggy had a small (5-6mm) cut or deep scratch on her face near her nose. There was a tiny amount of dried blood, but no signs of serious bleeding. Doesn't look deep. Just clean it and leave it be? Or does this require a trip to the vet?

Thanks!
