I would see a physician. Once the skin heals, apply Plato's Scar Serum twice daily followed by fractional lasers for the scars.

A dog bite can be very serious and can
lead to infection. Please see a physician.You may need antibiotics.
Best, Dr. Emer.
I'm sorry to hear about your injury. I would definitely get into your doctor today. These can get nasty in a hurry. I would start on an antibiotic, and watch it closely. If you get more swelling, pain, redness, or drainage, then a trip to the ER may be necessary.
