A small area of infection can be eliminated by some pet sprays or ointments, such as Peter Fen, dog mites or Golden Shield Anti-inflammatory Mite Cream.

But if it's a large area infection, it's best to shave it off. The easiest way is to go to the vet and give Labrador an injection.

In addition, pay attention to diet. The outbreak of general skin diseases shows that Labrador's skin resistance is weak and the metabolic function of endocrine system is poor. Try not to make the dog angry for a long time.
