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.

This could be a local irritation or local allergic reaction to something like a plastic dish. It could also be an indication of trauma, such as scraping her face or muzzle against the fence or something like that. I recommend you keep the area clean and dry and watch it closely for any increase in size, redness, any discharge or any pain. If it does not improve within a couple days I recommend having your veterinarian do an exam.

How to tell if my dog's skin bump is a rash or mosquito bite?

This looks like a rash from laying in the grass or something in the ground. I recommend cleaning the area with a warm wet cloth and applying a thin film of antibacterial ointment on it. If it is getting worse then take Jules in for an exam since it could be an infection and he may need antibiotics to clear it up. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Jules.

What is this smooth red spot with a white center on my dog's skin?

Thank you for the picture of Chipper's lesion. It appears to be a black fly bite. These lesions from the bite look bad, but typically they do not bother the pet. You don't need to do anything to treat it, these usually go away on their own over time. That being said, if this doesn't improve over the next week, it looks worse, or he's constantly itching it, then he will need to see a vet. I hope this helps!

My dog has skin bumps. Are they black fly bites or an infection?

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.

What's this red ring on my dog's skin? Is it a bug bite or infection?

It is possible this is an insect bite. Fly bites in particular can look like a red ring with a central pallor (pale area in the middle). It is tough to tell from the photo what the central area looks like. If it is raised and looks like it is filled with yellow/pus, then this could be a pustule which is a sign of skin infection. If the center is flat with the skin and just pale in color, then a bug bite is more likely.

My dog has a new pea-sized bump with a sore on his skin. What is it?

This looks like it could be an insect bite or sting, or a tick bite if they are in your area. Skin infections can also occasionally start this way. If you start to see more lesions similar to the one above, or if this bump begins to increase in size or have any discharge I would recommend having it examined by your veterinarian. If it is an insect bite it should be gone in the next 7-10 days or so. Monster is a handsome guy!

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

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.

Why does my dog have sudden red spots with black dots like bites?

It is hard to tell for sure it if both dogs have it I would be most suspicious of black fly bites, which are often just a local irritant. However, the other big concern would be petechia hemorrhages- which could come secondary to things like rat poison exposure! If they are feeling fine and were exposed to flies recently this is more likely but if they seem to feel off or had any other signs of concern it would be safer to take them in!
