Superficial Necrolytic Dermatitis in Dogs

Dogs of any breed, age, or gender can get an uncommon skin condition known as superficial necrotic dermatitis (SND). In this article, we will go over everything you need to know about this disorder.

Superficial Necrolytic Dermatitis (SND) is a rare skin disease that can affect dogs of any breed, age, or gender. It is a condition that causes the skin to become red, crusty, and itchy and can lead to hair loss and skin ulcerations. SND is frequently linked to illnesses like liver disease or pancreatic tumors, which leads experts to believe that it is brought on by a hormonal imbalance.

This article will provide an overview of SND, including its causes, symptoms, diagnosis, and treatment options, to help pet owners better understand this rare and potentially serious skin condition in dogs.


It is unclear what exactly causes Superficial Necrolytic Dermatitis (SND) in dogs. However it is thought to be related to hormonal imbalances in the body. In particular, hepatitis, liver cirrhosis, and pancreatic tumors are frequently linked to SND, as are other disorders that have an impact on the liver and pancreas.

These ailments may interfere with the metabolism of the dog, causing the body to contain less amino acids like methionine and tryptophan. The maintenance of healthy skin depends on amino acids, which are necessary for creating proteins. The skin's capacity to regenerate and repair itself is hindered when levels of these amino acids are low, which causes the typical signs of SND.

Poor nutrition, contact with pollutants, and the use of certain drugs are additional variables that may play a role in the onset of SND in dogs. However, some breeds, like the Doberman Pinscher, are thought to be more prone to SND than others, raising the possibility that heredity may be involved in its onset.


Superficial Necrolytic Dermatitis (SND) in dogs is characterized by a distinct set of symptoms that are typically observed on the face, paws, and groin area. The most common symptoms of SND in dogs include:

  • Red, crusty, and flaky skin: The skin may appear dry and flaky and may develop a rough, scaly texture.

  • Itching and discomfort: The affected areas of the skin may be extremely itchy, which can lead to excessive scratching, licking, and biting.

  • Hair loss: As the disease progresses, the hair in the affected areas may fall out, leaving patches.

  • Ulcerations of the skin: In serious cases, the skin may develop ulcers and bleed or leak.

  • Dogs with SND may display signs of discomfort or suffering, lose their appetite, and become lethargic.

Diagnosis of Necrotizing Migratory Erythema

Due to the symptoms' similarity to those of other skin illnesses, it might be difficult to diagnose Superficial Necrolytic Dermatitis in dogs. A veterinarian would normally do a comprehensive physical examination and run a number of diagnostic tests to determine the exact diagnosis. They may consist of:

  • Skin biopsy: A small sample of skin may be taken and examined under a microscope to look for characteristic changes seen in SND.

  • Blood tests: Checking the levels of amino acids, liver enzymes, and other markers of pancreatic and liver function can be done through blood tests.

  • Urinalysis: An analysis of the dog's urine can assist in identifying alterations in their metabolic processes that may be causing skin problems.

  • Imaging tests: X-rays or ultrasounds may be used to evaluate the liver and pancreas for signs of disease.

Treatment Options

The underlying cause of the condition affects how to treat erythema in dogs. Treatment of the underlying disease is frequently required to address the skin symptoms in situations when SND is connected to a liver or pancreatic condition. For canine SND, the following treatments may be used:

  • Nutritional therapy: Providing a diet that is rich in protein and essential amino acids, including methionine and tryptophan, can help improve skin health in dogs with SND.

  • Medications: Corticosteroids and other immunosuppressive medications may be prescribed to help control the inflammation and itching associated with SND.

  • Topical treatments: Medicated shampoos, creams, and ointments may be used to help soothe and heal the affected skin.

  • Management of underlying conditions: In dogs with SND, treating the underlying liver or pancreatic disease, whether by medication, dietary modifications, or surgery, can also assist in alleviating the skin symptoms.

It can be difficult to treat SND in dogs, and it could take many months to get the symptoms under control. In addition, to stop the recurrence of skin problems, the underlying disease must frequently be managed over the long term.

How Can You Prevent Superficial Necrolytic Dermatitis In Dogs

Migratory necrolytic dermatitis can be difficult to prevent, as it is often associated with underlying conditions such as liver or pancreatic disease. However, dog owners can take the following actions to assist in promoting good skin and possibly lower their dog's risk of having SND:

  • Balanced diet: Provide a healthy diet that is balanced and rich in vital fatty acids, vitamins, and high-quality protein to help support good skin.

  • Regular veterinary visits: Frequent veterinary appointments can assist in identifying any underlying medical disorders that might be impacting the skin and general health of the dog.

  • Avoid exposure to toxins: Skin irritation and inflammation can be avoided by limiting the dog's exposure to pollutants, such as pesticides, cleaning products, and other chemicals.

  • Maintain good hygiene: Regular bathing and grooming can help remove dirt, debris, and bacteria that can add to skin irritation and infection.

These actions can improve general skin health and perhaps lower the chance of acquiring skin illnesses like SND, even if it may not be feasible to avoid the onset of SND totally.
