Why does my dog have a painful rash on his inner thigh?

Updated On September 23rd, 2025

Pet's info: Dog | Miniature Pinscher | Male | neutered | 20 lbs

Hi I have no idea where my dog acquired this strange blustery rash on his inner thigh but I noticed it today and it is very painful for him. It seemingly appeared overnight and I’ve been applied dog anti septic spray and veterinarian grade steroid/anti fungal/antibacterial cream to the rash which seems to be helping, the middle photo is before application of the anti septic and triple action cream. What does this look like to you?

Hello. This is very typical of an allergic dermatitis reaction. Your treatment is appropriate so just continue until the skin is fully healed. Then, at the first sign of it coming back, start the cream again. You should also contact your veterinarian to see if the newer anti-allergy medications like Apoquel or Cytopoint would be appropriate to prevent these flare ups from happening. Thanks for contacting Petco Pet Education Center, formerly Petcoach.

    Poor Leo! You are right that this does not look like a hot spot. It’s very possible that he could have an underlying allergy causing this rash to be a common problem. Definitely keep your appointment with you veterinarian. At home, you can try washing it daily with hand soap and rinsing it well. Once it is dry, apply a dab of coconut oil and rub it in well. Do this twice daily. The only thing is that you don’t want Leo to lick it off. I recommend he wear an elizabethan collar afterwards until the oil is fully absorbed. I hope this is helpful and please feel free to post any additional questions.

    Looks like a bit of a heat rash. I suggest you get these medicated wipes and wipe the area 2-3 times per day until healed. http://www.allivet.com/p-5446-mal-a-ket-medicated-wipes-50.aspx If no improvement or it gets worse at any time then I suggest you get Tank to your vet for an exam. Hope this helps. Best wishes.

I noticed these marks on his inner thigh, groin area, they don’t seem to bother him, they are not swollen or bloody. What could they be, and what can I do at home to help? Thanks
Hello and thank you for contacting Boop by Petco. I suspect these sores are from the skin rubbing against abdominal wall when Tucker is walking. It does happen to some dogs, particularly during warm months. Please, get a baby diaper rash cream or ointment and use it twice a day for 6-7 days. Make sure that you get a fragrance free one without vitamins or supplements (most of baby rash products are like that). If that doesn't help you will have to take Tucker to your vet to get a cream with an anti-inflammatory agent.

Lambeau has what it looks like to be a rash on his inner thighs. I gave him a bath today and put antiseptic shampoo on the area. Then put a sav cream on. Can you tell me what this is or what medicine I can put/give him?
Lesions like this are commonly bacterial and less commonly ringworm (which humans can get). Sometimes they are a problem by themselves but if they occur frequently or seem like they never go away fully, it can indicate and environmental or food allergy. Of the two allergies, environmental is the more common. You can wash those lesions every day. Once it is dry you can apply the salve as long as it is safe for pets, or coconut oil. Only a small amount is needed and you should rub it in well. Make sure Lambeau does not lick it as this could make it worse and ingesting those products may upset his stomach. If he doesn’t get better within a week, I recommend to have him seen by his veterinarian. I hope this is helpful and please feel free to post any additional questions.

Hi .. I am not sure what this rash is on my dog . We had a flea issue which has gotten a lot better . He is always scratching and biting. The rash is on his inner thighs and under armpits , a little on his stomach . I found a “hotspot” on the out sid
Unfortunately, you can’t tell the cause of the rash just by looks alone. It’s possible this is still related to the fleas in the environment or that this is an allergic reaction. This could be a mange as well. I recommend to treat him with a good flea product like Simparica. If you must use an over-the-counter product, use Frontline. This is still a good product but there are some resistance with fleas. Make sure to protect the area from any licking or scratching with an Elizabethan collar. You can wash the area once a day and rinse it well. Start him on an omega-3 fatty acid supplement. If this does not start to look better within a week or if it starts to get worse, have him examined by the veterinarian. I hope this helps and please feel free to post any additional questions.

She has a red area on the inside of her leg near her private area. It almost looks like dried blood but it won’t wipe off, maybe a rash?
Thanks for using Boop by Petco! This is possibly due to allergies. It really comes down to figuring out what is causing her allergies so that they can be treated or the specific allergen avoided. A secondary infection is likely and also needs to be addressed. There are many things that can cause allergies though in most cases they can be broken down into 3 big categories: flea, food and environmental allergies. Allergies are usually worked up in a stepwise fashion starting with flea allergies as this is the easiest and cheapest to take care of. If not on a flea preventative, then it would be a good idea to get started on one. If already on one then it would be a good idea to change to something else (there are many new products out in the market). If not improved in 1-3 months then it is time to move on and check for food allergies by switching to a novel diet (new protein and new carbohydrate). If that does not seem to be the issue then you are left out having to check for envir

My dog has a rash in his right armpit and elbow. We took him to the vet and they weren't sure what could be causing it. They prescribed him Betafuse vet gel and told us to use it twice a day for 2 weeks. It's been 2 weeks now and the rash has gotten

My Dog has a severe rash between his thighs it looks a lot like when humans develop a bad case of chaffing very similar .. I have a cream for humans called DERMAID 1% , would this cream that is very effective on humans be suitable for dogs.. ? This
I am sorry to hear about your dog. This medication appears to have hydrocorisone as an active ingredient. This will help decrease inflammation of the skin, but often in these cases if this is an ongoing rash there is a secondary bacterial or yeast infection in the area. You could try the dermaid but often with cremes a dog will lick it off and then it doesn't have enough contact time with the skin, so I would consider putting an e-collar on her if she is licking at the area. You could also try a medicated shampoo such as Duoxo chlorhexidine shampoo. If this isn't improving then a trip to the vet is recommended.

My dog sudden has a new rash, started red itchy, now darkening can I use triple antibody cream or hydrocortisone cream on her
I don't think either of those will help much, but they won't hurt, just make sure that your dog doesn't lick it off. This rash looks evident of chronic inflammation, which could be caused by atopy, flea allergies, food allergies, chronic yeast or bacterial infection, mites, etc. I would recommend that you have your dog examined by a vet so that the actual cause of the rash can be diagnosed and treated to prevent flare-ups on the skin.
