How can I identify a dog scratch?

Question

Hello doctor,

I was standing on a roadside, and suddenly a dog passed behind me. I did not know if he scratched me or not. I did not feel it at that time, but after a few days, I saw some red dots and an itching type pattern on my knee side right now. I am so confused if it is because of that dog scratch or it is my phobia. Is anyone feeling the same thing? I would love to talk with people who are feeling the same. I am so exhausted.

Please help.

Thank you.

Hello,

Welcome to icliniq.com.

I understand your concern.

I can understand how distressing and exhausting this situation feels for you. You did the right thing by seeking clarity instead of staying alone with fear.

Based on what you described, the event itself does not suggest a dangerous exposure. You were standing by the roadside when a dog passed behind you, and at that moment, you did not feel any bite, scratch, pain, or bleeding. This detail is very important medically.

A rabies-related exposure requires a clear bite or scratch with a break in the skin, which is usually immediately noticeable. Rabies cannot be transmitted through intact skin, and it does not appear days later as mild itching or red dots. The delayed appearance of itchy red marks on the knee strongly argues against any dog-related injury or infection.

From a dermatological perspective, your attached picture(attachment removed to protect patient's identity) has scratch marks that are far more consistent with excoriation marks, mild contact dermatitis, insect bite reactions, or irritation caused by scratching, sometimes even scratching that happens unconsciously.

Anxiety and fear significantly heighten skin sensitivity, making normal or minor skin changes feel alarming and unusual. This is a very common experience, and many people go through similar fears after unexpected encounters with animals, even when no injury has occurred.

Medically speaking, since there are no visible wounds, no bleeding, and no immediate pain, there is no indication for rabies vaccination or emergency treatment. Your symptoms do not match the pattern of rabies exposure or progression.

Please take measures like avoiding scratching. Apply Calamine lotion day and night on the area for seven days, keep the area moisturized, and take tablet Rigix(Cetirizine) 10 mg (milligrams) at bedtime for itching if needed.

I hope this helps.

Kindly follow up if you have more concerns.
