My vet recommended Clotrimazole 1% solution in the form of spray for my dog's skin problem caused by yeast. It is quite helpful but expensive, I think more then $20 for 30 ml bottle. When I needed a refill I searched online rather than going back to the vet, and VetDepot had the same solution for much less. I'm using the same spray bottle.

I can't believe this only cost $5. It's way cheaper than the other antifungal spray I was using and it seems to work just as good.
