I have a pet bunny that is about 4 years old and appears to have snuffles.  It was just recently treated with Baytril (10 days, twice a day) but still has this condition.  Now I have been given IC Gentamicin to go into his eyes twice a day as a topical treatment.  He has no discharge in his eyes or nose and is eating fine.  I was told this could also be a tooth condition.  If the drops don't work, and he does not have any issues with his teeth, what else can be done?  There have been no changes on the environment where we live and the house is heated with forced hot water.  A humidifer was suggested but the house is not dry.  Any suggestions would be greatly appreciated
