What are Discoid Lupus Erythematosus?

Being one of the most common autoimmune skin disorder in dogs in the United States, DLE was diagnosed in large numbers in the 70’s and 80’s. However, today there are many fewer cases of true lupus that are diagnosed. DLE can mimic other skin disorders and this does make it somewhat difficult to differentiate. 

Some of the disorders that it may look like are mucocutaneous pyoderma (dermatitis that presents due to use of antibiotics), pemphigus complex, cutaneous drug reaction, erythema multiforme, cutaneous lymphoma, uveodermatologic syndrome, solar dermatitis (collie nose), systemic fungal infections, tick borne diseases, cancer, kidney disease, heart disease, and viral infection, amongst others. 

Most of the time your dog will not present with any pain or discomfort, rather you will notice changes around his nose in regards to color, texture, scabs etc. Your dog will present with irritation and possible hair loss around his nose among other symptoms. These symptoms will be discussed below in depth.

Discoid lupus erythematosus (DLE) is a common autoimmune skin condition in dogs. Symptoms will be mostly in his nasal area but can also impact other areas of his face and head. It is relatively easy to diagnose and is also treatable.

Symptoms of Discoid Lupus Erythematosus in Dogs

Symptoms are generalized and can mimic other skin conditions. Some of the symptoms are listed below. 

  • Depigmentation – Your dog’s nose may begin to lose its color as well as his lips
  • Scaling – You may notice your dog’s nose begin to develop a “crust” on it as well as his skin developing dandruff
  • Erythema – His skin may begin to redden in patches around his limbs, mouth, and ears 
  • Erosions – Ulcers may begin to develop on his nose and other areas of his head and limbs; these ulcers can appear on or in his ears, mouth, tongue and genitalia 
  • Alopecia – He may begin to lose his hair around his nose and other areas of his face and body without other explanation 
  • Your dog’s nose may lose its bumpiness and appear flat and turn a gray color
  • Initial photo dermatitis – your dog may have had a reaction to sunlight that resulted in ongoing problems such as DLE
  • Aggravated by sunlight exposure – When he is out in the sunlight without protection his symptoms may flare up


There are certain breeds of dogs that have been identified as having a higher possible risk of developing DLE

  • Collies
  • Shelties
  • German Shepherds
  • Siberian Huskies
  • Brittany Spaniels

Causes of Discoid Lupus Erythematosus in Dogs

There is, unfortunately, no known cause for DLE and it is thought to be a hereditary condition. It has been seen in some cases that your dog most likely had an allergic reaction to sunlight and then began to develop DLE symptoms after that. If your dog is young to middle aged, he may also be at a higher risk of developing DLE.

Diagnosis of Discoid Lupus Erythematosus in Dogs

Diagnosing discoid lupus erythematosus in dogs can sometimes be difficult due to how many other disorders can be very similar in their symptoms. Your veterinarian will want to know about any changes to your dog’s environment or eating habits to determine if it is possible he is having an allergic reaction to something. Your doctor will also want to know what things you have noticed that have you concerned, such as change in his nose color or ulcers.

Your veterinarian will want to take a biopsy of your pet’s skin to better help with diagnosis as well as blood work to eliminate other possible causes of his symptoms. Formal diagnosis of DLE will be done via a physical exam, a detailed history of your dog’s medical care, biopsy results, and how he reacts to trial treatments.

Treatment of Discoid Lupus Erythematosus in Dogs

Treatment will be to help your dog’s symptoms rather than curing his DLE as there is no cure. It is important to note that this is considered a cosmetic condition and most likely is not causing your dog any pain or discomfort. Treatment will be done in conjunction with other treatment options as discussed below.

Due to mucocutaneous pyoderma not being different in symptoms from DLE your dog may be treated with Cephalexin 10-15mg daily for 30 days primarily. Once this treatment is complete your veterinarian will move on to the next steps. 

Following treatment for possible mucocutaneous pyoderma, avoiding excessive sun exposure for your dog will be important. It will also be important to begin using sunscreen on him and providing him with vitamin E and omega 3 fatty acids. 

Lastly, there are the medications tetracycline and niacinamide which can be used together to help manage symptoms of DLE. This medication protocol does have side effects of possible vomiting, diarrhea and anorexia. Both of these medications can be trialed for up to 60 days and if there is no change in symptoms, they will be discontinued and an anti-inflammatory will replace them. 

Topical steroids can be used when the area of your dog’s body that is impacted is small enough. However, it is important to be aware that too strong of a steroid can cause scarring. The primary steroid cream is tacrolimus topical .1%, this steroid has been shown in at least one study to be enough to treat a dog’s DLE symptoms alone and all other medications could be stopped. Your dog will be slowly weaned down off the steroid medications as well.

Recovery of Discoid Lupus Erythematosus in Dogs

Treatment is lifelong and centers around sun protection first and foremost with continued monitoring for symptoms. Due to there being no known cause of DLE there is also no cure and therefore lifelong management will be necessary. Your veterinarian will suggest when to bring your dog back in and how to administer any medications prescribed.

Your dog’s symptoms can disappear within a few days to months and with your veterinarian, an appropriate course of treatment will be determined. Recovery will be based on your dog’s quality of life and symptoms abating.

My dog has DLE. She has what appears to be an infected callus close to her elbow. Its top layer of skin is black in color & scaley. She's been on clavamox for 6 weeks & it has gone from a quarter size lesion to a dime size. Could this be caused by DLE?

It doesn’t sound like discoid lupus erythematosus to be causing black scaly skin directly, but it sounds more like lichenification secondary to something else like an infection. But from your description it sounds like the area is getting smaller shrinking from the size of a quarter to a dime; I would recommend you continue with the treatment prescribed and discuss with your Veterinarian at your next visit.

Has Symptoms

crusty nose

My 11 year old Lab Cobi was diagnosed with discoid lupus Erythematos via a nose biopsy. My Vet ordered the tacrolimus 1% drops and I did this faithfully for about a month. My issue was keeping him from licking after putting the drop on his nose. He was very good however could only keep him from licking for about 1 minute. I did buy a muzzle but I feel guilty doing this. Do you have any other suggestions? Was the tacrolimus the 1st medication that should have been tried or could an oral antibiotic been used to try to decrease the symptoms prior to the tacrolimus? Thanks for your help

Generally in cases of discoid lupus erythematosus, a topical approach is attempted first using tacrolimus and preventing exposure to sunlight; if there is no improvement with topical treatment then systemic treatment would then be considered by your Veterinarian. Whilst the muzzle isn’t ideal, it is all for a good cause in the long term; you could try using a nose protector which is designed specifically for this issue at the link below.

Rescue Chinese Crested 6 year old netured male, crusty bleeding oozing sores just below back bone on right side, pathology report says DLE . We’ve tried oral and topical steroids no effect. I stared using Zinc oxide on worst lesions and have had very good results. However I may have over dosed him in Zinc, he start e throwing up Monday, and has thrown up once a day. My regular Vet put him on cerenia and ranitidine and no stomachs problems since. So now not using Zinc oxide, and worried what to use in him. Have tried all types of antibiotic creams RX and over counter, plus anti fungal, nothing has helped as much as the zinc oxide. suggestions as to topical meds and perhaps oral?

Commonly the biggest problem with zinc oxide is when dogs lick themselves, if you have exhausted all other products you should consider using the zinc oxide again but placing a cone on Yoshi or a shirt which covers the affected area. I cannot think of anything else you could use which probably hasn’t been tried already. Regards Dr Callum Turner DVM

Thank you that confirms what my GP. Vet told me, I keep jammies on Yoshi all the time. Am happy to get your opinion!

Unfortunately, I do not fully understand your question; it sounds like Samson has some sores on his side and they are weeping (weed?). If this is the case, keep the sores clean with a dilute antiseptic and take Samson to your Veterinarian for an examination. Regards Dr Callum Turner DVM

Hi! My dog seemed anxious when we came home after a day being out of town most of the day. She was pacing and didn't seem herself. She was with my mother all day and she noticed this too. She also had what appeared to be a welt on her nose and she was rubbing her nose against us a lot and shaking her head. She finally went to sleep and woke up around 3am and started pacing from room to room and tried to get on the bed and seemed like she was trying to tell me something. I tried feeding her, taking her outside, all the normal things and I still couldn't figure out was wrong. Also near that welt or bite the top of her head felt lumpy and swollen. She finally settled after an hour. That morning we took her to the vet who ran blood work and all came back perfect according to her. She did note that her temp was 103 and put her on amoxicillin and carpofen to be taken every 12 hours. We went home gave her the meds at 1130am and she ate a little hear and there then started to become lethargic and then eight hours after meds started throwing up. She did this four times. And at 3am she woke up with one eye swollen and went back to sleep and woke up two hours later with other eye swollen. We tool her to emergency room vet and they felt it was an allergic reaction to one of the med, so they took her off both and gave her a shot of benadryl and cerenia and sent us home with two more doses of cerenia. She was lethargic the rest of the day and ate only a little and then today woke up, still lethargic and refused to eat anything. She has never refused food. She still wasn't herself but then I gave her the first dose of cerenia and a bit over an hour later she started eating and has been trying food ever since. I don't know if it's the meds or if she's getting better and also her nose remains red and there is no longer a welts... could any of this be symptoms of lupus? The nurse in the ER mentioned that her nose reminded her of a dog that she saw that had an autoimmune disorder. I'm so lost :(

Thank you for your email. Without seeing Nilla, I am not sure if she ma have an immune disorder, or an allergic reaction. It seems reasonable to give the medication a chance to work, as she seems to be improving from your description, and to follow up with your veterinarian if she is not improving, just to be sure. they'll be able to examine her, determine what might be going on, and recommend any testing or treatment that might be needed. I hope that she is okay.
