Monistat Dog Yeast Ears. To treat a dog ear yeast infection, monistat should first be mixed with equal parts hydrocortisone cream in a small dish. The vet told me to go to the dollar store and buy the generic monistat and use it for 10 days.

An infection is referred to as yeast otitis. It's generally found on the paws, ear canals, armpits, jowls, anal area, and any skin folds that your pooch may have. Conofite only treats yeast, so i don't use that much.
