wha? ypur question was a bit random.
If you asking about problems they can have with there noses then prepare for along answer as it involves there eyes too.
King charlies as i call them are bred to breed characteristics which means a very short snout. Due to this they can have very short tear ducts (which helps remove dirt from the eyes) therefore there eyes require regular cleaning, if an infection occurs it MUST be dealt with immediately to prevent long term damage.
discharge from the nose is probably from the tear ducts but all ways get it double checked by your vet!
as i said your question was a bit odd so i hope i have helped??????
