When dogs have ringworm and hair loss, we need to find out the cause first and then decide what medicine to use. If it is fungus, we can use some antifungal drugs. If it is parasites, we need to deworm or inject some drugs to kill the parasites. If there is still bacterial infection, we need to use antibiotics to treat it.
Tip:
If we want dogs to have no skin diseases, we need to keep their bodies dry, take them for exercise and sun exposure, and add more nutrients.
