My dog is a 1 year 5 months old male spitz. From few days i was observing a red coloured patch around its left nose. It seems as if there has been some hair loss. My local vet has prescribed a lotion named wakazole containing miconazole nitrate.But while applying it my dog gets very irritated and licks all over.I am applying it from last three days but the patch has not decreased.So i want to know is there any oral medicine as an alternative for this ailment.If yes then how to give it and for how long to continue?i would be thankful for your advice.
