Updated On September 23rd, 2025

Pet's info: Dog | Fox Terrier | Male | neutered | 11 years and 5 months old | 15 lbs

My dog suddenly has a bunch of red spots on his stomach, chest and groin. They are not raised, and do not seem to be itchy. One is very target-shaped in appearance. Can you please tell me what these are?

These are likely fly or insect bites. They should fade in the next day or two. If he begins to itch, contact your veterinarian for a dose of Benadryl (diphenhydramine). Place an e-collar (cone) on him to prevent licking. These bites are common in the Spring.

    Thank you for your question. These spots are similar to what we see with insect bites, fly bites in particular. These bites usually resolve in a few days. If the spots are getting larger in size or become open sores or have a discharge coming from them then an examination by Bailey's vet is recommended.

Hi! I found these on my puppy's belly, it doesn't seem to bother him, it's neither itch nor painful, we are traveling in national parks, is this some kind of insect bites? Do I have to do anything about it?
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!

Found these spots on my dog dog stomach today
Your dog could be suffering from an allergy, mites, fleas, a bacterial or fungal infection. each of these requires a different treatment, so it is important to find out what is causing the itch. For now I would observe and monitor the skin condition. Should it spread, you will need to take your dog to a veterinarian for a skin exam. Your vet will do a thorough exam and maybe a a skin scrape. He will then discuss the options with you and then prescribe medications, possibly give an injection to stop the itching, if any is present.

My pet has been on flea and tick prevention his whole life but all of a sudden we left him with a family member when we went out of town and when we got him back he had all of these red mark on him. We thought they were tick bites but have not found
I just saw an article about something like this today. These may be fly bites. You're in the right area for black flies and these marks look similar to the ones in the article (https://www.goodhousekeeping.com/life/pets/a27755129/red-spots-on-dog-stomach/). If he is scratching excessively or seems uncomfortable, take him to see you vet, but if these are indeed black fly bites, the season is short and then they're gone.

What are these red marks on my dog’s belly? They are not her nipples and I have never seen them before. Does she need a vet visit?
Ouch! It looks like there may be a bit of contact dermatitis (allergy) going on. This can happen for a number of reasons including rolling in something that caused irritation (grass, dusty floors, etc), food allergies, or even minor infections causing irritation. You can try giving a benadryl at home to help with minor itchiness. An Elizabethan (cone) collar or T-shirt over the area is also a good idea to keep Ellie from licking it so she can't cause more irritation or infection. If the area doesn't improve or resolve in a day or two, is very itchy, painful, or worsens, then a vet visit is best to find the underlying causes so it can be treated.

Hi, my dog had a couple of red spots on his belly when we came back from camping last week, it got worse over the last couple of days since he has been scratching. We gave him a flea treatment and dewormed him Tuesday but it seems to be getting worse

My dog is getting these weird red spots on his belly.
Hello. Those red spots are a clear indication of some significant inflammation going on. The issue is what is the cause. It may be allergy derived, or there could be some infection involved as well. You can spray the area with an over the counter spray containing hydrocortisone ( Wal Mart sells Pro Sense All Dogs Itch Spray with Hydrocortisone ). If this does not help, you should see Bama's veterinarian for further work-up. Thanks for using Boop by Petco.

Early today my dog was outside laying and playing in the grass and when I came to bring him in I noticed a bunch of red spots around his gential area. They don’t look like bits more like itch spots. Like the size of a bingo stamper. I have no idea wh
The most common reason that we will see marks like that show up on the non-haired skin of the abdomen are because of black fly or other insect bites. They do not generally tend to be itchy, but they can be. If any of the areas are becoming swollen, enlarging or appearing to spread, then Apollo should see your veterinarian. Otherwise, the areas tend to fade on their own. https://www.vin.com/veterinarypartner/default.aspx?pid=19239&id=7986755 Good luck! I hope that was helpful. Thanks for using Boop by Petco.

My dog has large red bumps on him on his belly , face, armpits? He's only 9 months
This looks like an allergic reaction to something or general allergies. Make sure he is on a good veterinary prescribed flea control. You can try to shampoo him in a chlorhexidine shampoo to help heal the red bumps. You can also Give him 75 mg (3 adult) Benadryl to help with any itching. If he isn't itching and/or the bumps aren't improving, I would contact your vet for an exam to ensure he doesn't need a stronger allergy medicine or antibiotics. I hope this helps!

What are the red spots on my dog's belly
Although a picture would help defining the underlying cause of it, this is probably due to an allergy, although it could also be infection (bacterial or fungal) or mites . First of all, in order to rule out skin parasites, you will need to treat with a high quality flea treatment (advocate or advantage), then ask the vet to perform a skin scrape - this might reveal an infection or a mite infestation. If all of those came back negative, the next step is to treat the allergy symptomatically and try to discover the cause of the allergy. Three main type of allergies are usually affecting pets: food allergies, flea and parasite related ones and environmental type (allergens coming from trees, pollens, dust etc etc). Some medications can be given by the vet in order to repair the skin lesions (steroids and antibiotics). Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.
