Most often when we see a lesion like this on the skin it is the result of an insect bite, in particular a biting fly such as a black fly. If your dog is acting normally then I would just monitor the area. If the lesion grows in size, becomes raised or oozes a discharge, or your dog develops many more lesions, becomes lethargic or very itchy a vet exam is recommended.
