My Dog Has A Rash Near His Private Area: Causes & Treatment

Has your dog been excessively scratching itself? Does your dog devote an unhealthy amount of time licking its private area?

Under all that fur and the silky coat, it might be difficult for you to diagnose, but your dog could likely be suffering from a skin condition like a rash.

A dog with a skin rash may show signs like excessive hair loss, skin redness, itching, dry, flaky skin, red bumps, sores, and scabs.

The causes of such a rash could be bacterial infections, parasites, allergens, hormonal imbalances, and other health conditions.

Your dog could get a skin rash anywhere on its body. But it is the moist areas that are often affected. So, rashes are common around the groin, armpits, ears, and skin folds.

So, if you are wondering, my dog has a rash near his private area, what can be the cause, what can I do, and when should I visit the vet – the article will attempt to provide you with all the answers.

My Dog Has A Rash Near Private Area: Causes & Treatment

Skin irritation is pretty common in the canine world. Depending on the dog’s health, age, where you live, and hygiene conditions, there are several different causes that can lead to a rash.

Here are some of the possible causes why your dog could have a rash near its private area.

1. Environmental Allergens

Do you find your dog excessively scratching itself? If yes, one of the common causes of chronic itching is environmental allergens. The skin condition is known as atopic dermatitis and is caused as a result of a hypersensitivity reaction to allergens.

Environmental allergens can be present throughout the year or could make their presence felt in different seasons like spring. For example, dust and mold are allergens that can be present anywhere you go, any time of the year. Pollen is an example of a seasonal allergen.

When the dog’s skin is exposed to these allergens or inhales them, it can start showing signs of an allergic reaction. The dog’s genetic makeup and immune system response are majorly responsible for triggering the reaction than the allergens themselves.

A dog with atopic dermatitis can show signs like:

Runny nose and eyes are less common symptoms seen in dogs with atopic dermatitis. The dog may not outgrow its allergies as it grows, so it would be best to visit the vet for a proper diagnosis and treatment.


Pinpointing the exact allergen affecting your pet can be a complex process. The vet may perform intradermal or blood allergy testing to find the cause.

According to AKC, the best way to protect your dog is to keep it away from the allergen. But this is not always possible when the issue is environmental. For example, you cannot keep your dog locked up inside the house.

Immunotherapy is one of the treatment options available. You can give the dog injections to help build its tolerance level to the allergen.

Other treatments may involve anti-inflammatory, anti-bacterial, and anti-fungal medications and topicals.

2. Food Allergy

Another allergy type that may cause the skin around the dog’s private area and around its paws and ears to develop a rash is a food allergy.

Like environmental allergens, the dog’s immune system overreacts to the substances in the food. Now, it could be a protein or a complex carbohydrate in the food triggering the production of antibodies.

Food allergies typically develop in the long term. For example, your dog may be okay with eating chicken, but with prolonged exposure, it can develop an allergic reaction to the protein.

Dairy and meat are the two common food allergens canines cannot handle. Examples include milk, chicken, beef, gluten, and soy.

Apart from a skin rash, dogs with food allergies can show signs like:

  • Itchy skin
  • Stomach upset
  • Vomiting
  • Diarrhea
  • Lethargy
  • Weight loss

Again, it would be best to visit the vet if your dog shows the above signs. There is no cure for this allergy, but the vet can help manage the symptoms.


Diagnosing a food allergy can be a long, drawn-out process. One of the accurate methods of identifying the allergen is to put the pet on a hypoallergenic diet for 8 to 12 weeks. You cannot include any ingredients that the pet has eaten in the past.

After 12 weeks, you can reintroduce the pet’s old food. If the pet’s symptoms return, it is diagnosed with a food allergy.

Once the food allergen is identified, it would be best to eliminate it from the dog’s diet. The vet can provide a customized diet plan ensuring the dog gets the right balance of nutrients even after the allergen is removed.

3. Bacterial Infections

Bacterial infections are common among canines. It can affect dogs of all breeds, shapes, and sizes, but they are especially seen in puppies and young dogs.

Pyoderma is a superficial infection that typically results from an underlying condition. Your dog’s hair follicles and surrounding skin could be affected. In addition, the dog’s skin barrier could be broken due to the condition, and continued exposure to moisture leads to infections.

There could be several causes for pyoderma. For example, injury, insect bite, allergy, poor diet, hormonal disorders, foreign bodies, or long-time administration of immuno-suppresant drugs could be probable causes.

Your dog could have skin rashes around its private areas, armpits, ears, skin folds, and space between its toes and between mammary glands in females.

Apart from rashes, the dog may show additional signs like:

  • Hair loss
  • Skin discoloration
  • Red bumps
  • Flaking skin

In the case of puppies, pyoderma may especially show up around their armpits and groin areas. You may notice red bumps that may scab or scale.


Identifying the underlying cause of pyoderma can be a task in itself. Depending on the pet’s symptoms and medical history, the vet may perform tests like skin cytology, skin cultures, fungal cultures, blood tests, and antibiotic sensitivity tests.

The treatment plan involves treating the infection and the underlying cause. Or else the infection will reoccur. The vet may put the dog on an antibiotic treatment plan for three to four weeks. In addition, topicals, shampoos, and medicated sprays may be prescribed.

Other medication or diet changes may be required depending on the underlying cause.

4. Fleas and Ticks

Fleas and Ticks

Fleas and ticks are parasites that can make life difficult for your pets. They can cause severe skin irritation and rashes and complicate your dog’s health.

These parasites can trouble your dog throughout the year, but they are more common during the warmer months.

Fleas are wingless parasites that feed on your pet’s blood. Your dog’s furry coat makes it a warm and ideal environment for the fleas to produce offspring.

You or your dog can easily bring fleas in from the outside. They could leave behind eggs and larvae in the upholstery and rugs, where they can survive for months.

Similar to fleas, even ticks feed on your pet’s blood. But they tend to be more dangerous than fleas. Ticks latch onto the host’s skin, bite them, bury their heads in the skin, and feed on the blood. They are commonly found around the dog’s ear, neck, and feet but can be found anywhere on the dog’s body.

If left untreated, ticks can lead to complications like anemia, tick paralysis, Lyme disease, and cytauxzoonosis.

Dogs with fleas and ticks on their body can show signs like:

  • Skin rashes
  • Extreme itching and irritation
  • Excessive chewing and licking
  • Hair loss

Fleas and ticks can be challenging to see with the naked eye. But if you run your hands through the dog’s fur, you may be able to feel the parasites. Please visit the vet if you suspect your pet has fleas and ticks on its body, as the condition requires treatment.


Depending on the severity of the condition, the vet may prescribe oral medication or topicals to be applied. The vet may also recommend the use of medicated shampoos, sprays, and powders.

You must clean up your dog’s immediate surroundings as well. This can include their beds, toys, the area they sleep in, your rooms, upholstery, and rugs, among others.

If you notice ticks on your dog’s body, you best remove them with a tweezer. However, be careful during the process, as the tick’s blood can infect other pets or even you.

Using a tweezer, grasp the tick close to the dog’s skin. Pull the tick in an upward motion. Please do not put too much pressure or twist the tick, as it can cause the infected blood to spread.

Once the tick is removed, monitor the area for any infection. If you see any redness or scabbing, please visit the vet.

For fleas and ticks, prevention is the best way to go. According to AKC, using topical prevention treatments, flea collars, using medicated shampoos, actively checking your dog, using flea combs, and keeping your environment clean are good preventive measures.

5. Yeast Infection

This is another common answer to the question, why my dog has a rash near his private area? Your dog’s skin normally has bacteria and fungi on it. However, when your dog is healthy, these organisms do not pose any problems.

But when the skin’s barrier is broken, the dog is injured or is suffering from a suppressed immune system; the same organisms could pose a problem. The environment then becomes ideal for the bacteria and fungi to thrive, resulting in a yeast infection.

The infection is typically caused by a fungus called Malassezia. Some other causes of yeast infection could be allergies, foreign objects, exposure to harmful substances like cleaning products, or food that is high in sugar and carbs.

Canines with a yeast infection can show signs like:

  • Skin rashes
  • Redness
  • Itching
  • Crusty and flaky skin
  • Musty odor
  • Recurring ear infections


The vet will have to take a sample and test it for a confirmed yeast infection diagnosis. Skin scraping, skin biopsy, and cotton swab samples are common methods for obtaining a skin sample. The sample is then studied under a microscope.

Once confirmed, the treatment plan may involve oral medications and topicals. Depending on the severity of the infection, the dog may be required to be on medication for four to twelve weeks.

The vet may prescribe medicated shampoos. If the infection has spread, then the dog’s skin should remain in contact with shampoo for a minimum of 10 minutes. A topical ointment may be prescribed for daily use if the infection is limited to certain areas.

6. Heat Rash

When your pet’s skin overheats, it can get a heat rash. Dogs cannot sweat as humans do. Panting is how they try to cool down. But this may not be quick enough on a hot summer day.

The areas on the dog’s body that are not covered by fur, that are tender and remain moist, are more susceptible to heat rashes. These rashes can appear on your dog’s stomach, private area, skin folds, and wrinkles.

If you find your dog panting, it would be best to bring it inside or take it to a shaded area where it can cool down and relax. Then, give it some water to drink.

A dog with heat rash may show signs like:

  • Skin redness
  • Tenderness
  • Itching
  • Boils or pimples
  • Foul odor

If your dog has a heat rash, it would be best to treat the area. Leaving a rash untreated can worsen the skin’s condition and lead to infections.


If your dog is panting, drooling, and has difficulty breathing, they are signs its body has overheated. Take the dog to a well-ventilated and cool area.

You can spray tepid water on the dog’s body. However, do not use cold water, as it can lower the dog’s body temperature too quickly, which is not good either.

If you see signs of a minor heat rash, covering the area with a cold compress should help. The vet may suggest using hydrocortisone cream or aloe vera to relieve skin irritation.

If the dog’s skin becomes too tender, paying the vet a visit would be best.

7. Vaginal Inflammation

Vaginal Inflammation

Female dogs, puppies or older, spayed or unspayed, can suffer from vaginal inflammation. You may notice your dog’s vaginal area has become swollen and red, and there is also discharge.

The condition can be categorized into two types depending on the dog’s age. For example, in young puppies, the condition is known as juvenile vaginitis, and in older dogs, it is known as adult-onset vaginitis.

There could be several causes of vaginal inflammation. Some of these causes include allergies, UTI, infection, presence of foreign bodies, pee or poop causing irritation, cancer, and physical abnormalities.

Dogs with vaginal inflammation can show signs like:

  • Skin rashes
  • Frequent urination
  • Excessive licking of private area
  • Red or swollen vulva
  • Difficulty urinating

Please contact the vet if your dog shows any of the above signs. The underlying cause will have to be identified and treated for the inflammation to settle and not recur.


The vet may start with understanding the dog’s symptoms, diet, routine, medical history, and any recent changes made.

The vet may perform a thorough physical examination of the vaginal area. Imaging techniques like vaginascopy and ultrasound may be used to detect any abnormalities, tumors, or lesions. The vet may scrape some tissue around the dog’s vagina to check for an infection.

The treatment depends on the results of the tests performed by the vet. Surgery will be an option if the cause is a tumor or an abnormality. The vet will prescribe a long course of oral medications if it is an infection.

In mild cases, keeping the vaginal area clean and using mild prescribed wipes should be enough.

8. Exposure to Toxins

Exposure to Toxins

Seemingly innocent everyday products, food, and plants may be harmful to your pets. When exposed to such toxins, your dog can show an allergic reaction, like skin rashes.

Dogs are curious by nature; you will often find them snooping around non-edible products trying to figure out what they are. Everyday products like fabric softeners, mothballs, rat bait, paint, lawn fertilizers, and anti-freeze can be toxic to dogs. And thus, should be kept away from their reach.

When it comes to food items like chocolate, grape, garlic, onion, caffeine, and alcohol should not be a part of the dog’s diet. The toxicity levels can vary, but it would be best to avoid them.

If your dog ingests a toxic plant or brushes against one, it may show more signs than skin rashes. Some common plants that may be harmful to your dog are poison ivy, peace lily, yew bush, almond, foxglove, and hibiscus.

When exposed to toxins, apart from skin rashes, the dog can show signs like:

  • Skin sores and burns
  • Vomiting
  • Diarrhea
  • Lethargy
  • Behavioral changes
  • Difficulty breathing
  • Collapse


Some of these toxins may only turn into mild cases, but it would be best to contact the vet if you suspect the dog has been exposed to toxins.

The vet may need details about the amount of toxin ingested, symptoms, medical history, and the dog’s diet and routine. The vet may then call you to the clinic or advise you to monitor the pet’s condition at home. They may ask you to rinse the dog’s skin wherever it came into contact with the toxin.

If the toxin was recently ingested, less than four hours, the vet may try to induce vomiting. Do not try this at home, as it may cause more harm than good for the dog.

Depending on the symptoms, the vet may provide supportive care, like administering intravenous fluids and oxygen therapy.

9. Hormonal Imbalances

Hormonal Imbalances

Like humans, dogs also have hormones that regulate their mood, energy, and appetite. Skin changes are a common indication of hormonal imbalances in dogs.

There can be several causes of hormonal imbalances in dogs. One such condition is known as hypothyroidism. When the dog’s thyroid gland becomes underactive, its metabolism slows down. The causes for the condition may be immune-mediated disease and other idiopathic causes.

If your dog suffers from hypothyroidism, it can show signs like:

  • Dark skin pigmentation
  • Prone to skin and ear infections
  • Excessive shedding
  • Weight gain
  • Lethargy

Another hormonal condition that can affect canines’ is Cushing’s disease. The dog’s adrenal glands produce more cortisol than required in this condition. The cause could be prolonged administration of prednisone or dexamethasone or steroid medications or a tumor on the pituitary gland.

The symptoms of this condition can be similar to aging, and hence diagnosis becomes difficult.

If your dog has Cushing’s disease, it can show signs like:

  • Thinning of skin
  • Skin lesions
  • Extreme thirst
  • Frequent urination
  • Hair loss
  • Tiredness


Hypothyroidism is a condition that cannot be cured. But the condition can be managed with thyroid replacement hormone therapy. This therapy must be followed for the rest of the dog’s life. You can administer the medication orally.

You will need to work closely with the vet to determine the correct medication dosage. Initially, the vet will take a blood sample after the first month to test the thyroid levels. And then, the vet will repeat the process every six months to ensure the pet is not over or under-dosed.

In the case of Cushing’s disease, if the cause is a pituitary gland tumor then the vet may prescribe oral medications to destroy some part of the adrenal glands so cortisol production is regulated.

Surgery may be an option if the tumor is benign, but this option is rare in the canine world.

10. Genetics

Your dog’s genetic makeup could be one of the reasons for its frequent skin irritation issues. For example, according to PetMD, dogs with short coats are prone to skin irritation. Especially when these dogs have skin folds, the hair can poke onto either side, causing the pet discomfort.

Then you have conditions where the skin thickens abnormally. For example, breeds like Doberman Pinschers, Golden Retrievers, Cavalier King Charles Spaniel, and Rottweilers are prone to a condition called canine ichthyosiform dermatoses.

German Shorthaired Pointers can have a condition called hereditary lupoid dermatosis. Skin crusting is one of the symptoms of this condition.

The signs of these genetic health issues may vary from skin rashes, lesions, crusting, and flaking, to hair loss. Please discuss these signs with the vet.


If your pet has a genetic predisposition, then one cannot avoid the condition altogether. However, you can keep up with your pet’s hygiene, take precautionary measures and be on the lookout for any early signs. This may help catch the issue early on and begin treatment.

For example, in the case of short-coated dogs using medicated shampoos and frequently grooming the pet can help.

The condition may not be completely curable in the case of canine ichthyosiform dermatoses, but the signs can be managed with shampoos and other medications.


My dog has a rash near his private area – what can I do? As we have seen above, there could be several possible reasons for your dog’s skin rash.

It could be a reaction to an environmental or food allergen, a bacterial or yeast infection, fleas, or ticks. The condition could also result from a heat rash, hormonal imbalances, and genetics.

Apart from a skin rash, if you notice other signs like flaky skin, excessive itching or licking, scabbing, crusting, or pimples, please get in touch with the vet.

In most cases, the rash could be a result of an underlying health condition. So the vet will diagnose the cause and provide treatment for the rash and the underlying condition.
