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

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.

The most common reason that we see red circular rashes in dogs are actually bacterial skin infection. Tick bites rarely cause red circular rashes in dogs (it's more common in people). Ringworm certainly can cause a circular rash, but they often aren't red in dogs. I would recommend having your vet examine Chance and determine what they think is going on. They may be able to tell by looking at it, or they may need to do some special skin tests like skin scrapings or skin cytology in order to determine the best treatment for Chance. I hope that was helpful. Thanks for using Petco Pet Education Center, formerly Petcoach.

Skin lesions like Coco has can be caused by bacterial, parasitic or fungal infection, dietary or environmental allergies or sensitivities, immune system disorders, an insect bite like you mentioned, or a combination of the above. I recommend making an appointment to have Coco seen by your veterinarian to help determine the cause of the lesion you’ve noticed and to make sure it is treated appropriately. The vet will likely want to look at a sample from the area under the microscope to determine if there is an infection and to figure out what medication is appropriate for treatment. In the meantime, you can bathe Coco in hypoallergenic shampoo for dogs to clean the area, but this will likely not resolve the lesion.I recommend getting Coco on parasite prevention year round.

It is possible, though it looks more like it could be a bacterial infection. Ideally, take her in to the vet for an exam so that the proper treatment can be determined.

It could be an insect or tick bite, it could also be ringworm, if this does not get any better within a week you will need to take her to your vet in order to get it checked and treated. try to avoid contact as ringworm is contagious to humans as well.

Belle may have a skin infection (bacterial or fungal) or it could be a result of insect bites. Check her over for fleas or evidence of flea dirt and consider treating her for fleas just to be sure. Have her examined by your veterinarian to diagnose and treat any infection. If she is licking or chewing, place an e-collar (cone) on her until she sees the vet.

From the appearance in those photos, I suspect those are black fly bites. They can cause pretty dramatic round red lesions that are flat (not raised). While they look impressive, Gnocchi shouldn't be bothered by them. They will gradually go away (it can take a week or two) and are not dangerous. I hope this helps!
