My adopted rescue has alot of skin problems and his nasal folds being one of them. I use Baby Gold Bond and apply it with a Q-Tip and just roll it into the folds really well at least twice a day (avoiding his eyes).

As you probably already know, the issue is yeast. We with our bully we have found that a very small amount of over the counter yeast treatment for women, monostat, seemed to help with our dog. Anything that blocks the formation of yeast growth will help. You might want to get a perscription of tetracycline from your vet.

Or the creme, the generic form is Animax, it does wonders even overnight to kill the bacteria resposible for the "yuck nose fold". It has a steroid component which will help with the red rawness.

Desitin cream to soothe and protect or Gold Bond powder to dry the area. If it gets really infected you may need something from the vet like an antibiotic.

try phoning your regular veterinarian's office and ask if you can purchase this medication to clean a deep nose wrinkle. If you use the same vet and have been there recently, they should sell you this medication. If they don't dispense without an exam, be sure you keep a list of medications you want to keep in your cupboard, and ask to buy them when you do go next time; medications such as Animax ointment, a small bottle of chlorhexidine solution (4-6oz) and perhaps Malaseb shampoo (altho online suppliers will sell you these two latter items w/o Rx).
