My dog has a belly rash, but no ticks. Could it be a black fly bite?

My dog has this rash on her belly. I didn’t see any ticks on her at all recently. She has tick preventatives every month also. I believe it could be a black fly bite(I saw images online)

You are right, it could be black fly bites, it is the season for it and they can cause lesions like this. Unfortunately without seeing Sophie in person, I cannot make a definitive diagnosis. I would take her into the vet in the morning to have this diagnosed and treated. Best of luck.
