The dog keeps scratching after being dewormed or it is because of insect bites

The dog keeps scratching after being dewormed. This has nothing to do with external deworming. It mainly occurs after being bitten by bugs. This phenomenon makes the dog's skin feel itchy, so the owner needs to help the dog get a physical check-up in time.

The dog keeps scratching after deworming or because it is dirty

There is no way to deworm the dog if the dog is very dirty. The owner still needs to treat the dog. When cleaning, you need to pay attention to using pet-specific cleaning shampoo. You also need to pay attention to the frequency to avoid over-cleaning and infecting skin diseases.
