First, we need to determine what causes the dog to keep itching. It may be caused by an allergic reaction, skin irritation, and it may also be caused by itching caused by parasite infection. If it is an allergic reaction, you can try to take anti-allergic drugs to your dog; if it is infected with parasites, you can try to take anti-parasite drugs to your dog. If none of the above works, it is recommended that you take your dog to the veterinarian in time and the veterinarian will be diagnosed and treated.

The dog is itchy, and the first thing to do is to find out the cause. There are several main causes of common itching in clinical practice: skin diseases, skin allergies, and parasitic diseases, which require symptomatic treatment for different causes. If it is a skin disease and parasitic disease, local hair loss, scab, suppuration and other symptoms often occur, it is recommended to go to the hospital for treatment in time. If you have skin allergies, you can apply some dexamethasone ointment to relieve itching and avoid allergies. There are many reasons for itching in dogs, including long-term failure to take a bath, ectopic parasitic infections, and skin diseases. Among them, fleas are common in ectoparasite infections. When there are many fleas, you can clearly see many dark brown spots on the dog's hair.
