My dog has a sudden, raised, painless spot on her skin. What is it?

Updated On September 23rd, 2025

This raised plaque showed up on my dog in less than 24 hours. Does not itch nor is it painful. Located at bottom of rib cage. I cleaned it with alcohol and it peeled off to show pink skin as shown in the picture. I do not recall her having any wounds or injury here yesterday.

It could be a localized area of dermatitis. You can try an over the counter wound spray, like Vetericyn Plus, and see if the lesion resolves. If not, she should be examined by your vet to determine the cause and prescribe medications to treat.

    Sorry it is not possible to diagnose this from a photo. This needs to be seen by a veterinarian for a skin exam. This could be a fungal infection, skin tumors, bacterial infection and other skin conditions caused by autoimmune disease or even contact with a chemical or other irritating substance. I strongly suggest your client make make an appointment with his vet for an exam.

    This presentation could be due to a localized spot of skin infection (likely to be caused by bacteria but fungal infections can be considered as a differential diagnosis). A check up, appropriate disinfection and possibly antibiotics (oral, topical or in a shampoo formulation) are needed to solve the problem.

    This presentation could be due to a localized spot of skin infection (likely to be caused by bacteria). A check up, appropriate disinfection and antibiotics (oral, topical or in a shampoo formulation) are needed to solve the problem. Disinfection may be started at home with very diluted hibiscrub or betadine or salted water baths. Buster collar may be useful as well to avoid any licking/scratching (if any).

My dog had this on her back this morning. It wasn’t there when she went to bed. She sleeps inside. What could it be? It doesn’t seem to hurt her.

I discovered this on my dog Rexi, I have no idea what caused this. It wasn’t there this morning. What could this be and what should I do? I washed it with water and cleaned it with colloidal silver.

Hi, and thanks for your question. This presentation could be due to a trauma or localized spot of skin infection (likely to be caused by bacteria or fungal). A check up, appropriate disinfection and possibly antibiotics or antifungal meds (oral, topical or in a shampoo formulation) are needed to solve the problem. Disinfection can eventually be started at home with very diluted hibiscrub or betadine or salted water baths. Buster collar may be useful as well to avoid any licking.

This spot in my dog’s leg has light hair iam afraid it is something dangerous my oldest dog has it but eventually it was because seh sit too much on hatd land so the hair was removed once i solved this the hair came back.
Hello. All I can see is a small area of dermatitis on the leg. It can have many causes, but you can treat this with an over the counter skin antiseptic called Hibiclens. Gently scrub the skin twice a day & dab dry ( do not rinse ). Do this for about 2-3 weeks & the lesion should clear up. But since I cannot make any kind of actual diagnosis, if the skin becomes more irritated or the area does not seem to be healing, please consider seeing your veterinarian. Thanks for using Boop by Petco.

My dog has a small red round rash. No satellite lesions. Solid red. No hair loss. No apparent pain or itching. Any idea what it could be? I did not see any bugs attached there. He had a tick last week but it was on his flank. This area is on his lowe
Bo's lesion looks most suspicious for a bacterial skin infection, but could also be due to ringworm, mange, or bruising. Since it does not seem to be bothering him, you can monitor the lesion for the time being to see if it changes colors, grows, becomes itchy, or spreads elsewhere. You can also try bathing him with an antimicrobial shampoo (here is one example: http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=27982 ). However, if the lesion worsens or seems to be causing discomfort, it is worth taking a trip to the vet for evaluation. I hope that all goes well!

My dog has this on her skin what is it?
The picture makes it difficult to see. It's possible it may be a scab trying to heal, a minorly infected area of skin, or a wart/growth forming. It would be best to keep the area clean and dry and keep Belle from licking or chewing at the spot. If the area continues to change in appearance, is bothersome to Belle is hot to the touch, painful, or oozing debris, or doesn't seem to be healing, it is best to seek veterinary care in person. Your vet can take a look at and sample of the spot as needed and provide more tailored treatments depending on the cause.

Hi! My 9 month maltese has an unusual spot under her armpit. I can't make sense of what it is.. it may be a burn, a cut, a bug bite or something else.. I really don't know what to do about it please help! P.S I thought it would be good to mention t
Poor Masha! This looks like a relatively minor skin wound, from what I can tell in the photos. It's possible that her skin may have been accidentally nicked or caught in the clippers during her haircut yesterday - it's very easy for this to happen in small dogs with delicate skin. She also could have scraped or poked herself on something, or this could be a local inflammatory reaction to some type of insect bite. If this is the only spot like this you can see and she is acting normal otherwise, you could opt to monitor it for the next few days to see if it heals up on its own. You could also use a topical antibiotic spray such as Vetericyn or Nutri-Vet on the area as well, if you wish. If it does not seem to be healing within 5-7 days, or if the area around the wound becomes red and swollen, then it would be best to have her seen by a vet - in that case, she would likely need prescription antibiotics and anti-inflammatory medication to treat the problem.

What could these red spots on the inner left leg of my dog be? Should I be concerned, only on that area, noticed it yesterday.
It's possible that Feli has been licking or scratching this area, causing these abrasions. This type of lesion can develop pretty quickly - even overnight. Some of the most common causes of itching include allergies and fleas. Make sure that she's regularly receiving a good quality flea preventive (Bravecto, Nexgard, Credelio and Simparica are all great prescription options, and K9 Advantix II is available over the counter). You can also give her a bath in a gentle oatmeal or baby shampoo in case there are any lingering allergens on her coat causing irritation. You certainly don't need to rush her to a vet for these lesions alone, but if they get worse or spread, then you should take her to get checked out. When dogs scratch, they can damage the protective skin barrier, which can make them susceptible to developing skin infections. I hope that she's on the mend soon!
