Itching from a dog bite scar may be caused by wound healing, allergic reaction, rabies virus infection, or other reasons. A detailed analysis is as follows:

1. Wound Healing

After a dog bite, the wound gradually heals, and itching may occur during this process. No special treatment is required; simply maintain local cleanliness and hygiene.

2. Allergic Reaction

Following a dog bite, the body may develop an allergic reaction causing itching. Under a doctor's guidance, antihistamine medications such as chlorpheniramine maleate tablets or loratadine capsules can be used to relieve itching caused by the allergic reaction.

3. Rabies Virus Infection

If the wound is not promptly cleaned and treated after a dog bite, it may lead to rabies virus infection, which can cause itching. Under medical supervision, disinfectants such as povidone-iodine can be applied to the wound, along with medications like erythromycin ointment or amoxicillin granules for treatment.

In addition, itching could also result from flea infestation. If the itching is severe or accompanied by other symptoms such as fever or swelling, prompt medical attention is recommended for proper diagnosis and treatment by a qualified healthcare professional.
