Understanding Canine Lupus
Lupus in dogs, also known as systemic lupus erythematosus (SLE), is a serious autoimmune disease that affects the dog’s immune system, causing it to attack its own tissues on a cellular level. This immune-mediated disease can lead to inflammation and affect multiple organs and bodily systems. There are two main types of lupus that can occur in dogs: discoid erythematosus (DLE) and systemic lupus erythematosus (SLE) (WebMD).
What is Lupus in Dogs?
Lupus in dogs is an autoimmune disease where the dog’s immune system mistakenly identifies its own proteins as foreign and produces antibodies against them. These antibodies form immune complexes that can cause inflammation and damage to various organs and tissues in the body. The exact cause of lupus in dogs is still unknown, but it is believed to have a genetic predisposition and may be triggered by environmental factors (PetMD).
Types of Lupus in Dogs
-
Systemic Lupus Erythematosus (SLE): Systemic lupus erythematosus is the more severe form of lupus in dogs. It affects multiple organs and bodily systems, leading to widespread inflammation and tissue damage. SLE can cause the immune system to attack organs, skin, and glands in different dogs. Certain dog breeds, such as German Shepherds, Beagles, Poodles, Collies, Irish Setters, Afghan Hounds, and Shetland Sheepdogs, may be more prone to developing SLE.
-
Discoid Lupus Erythematosus (DLE): Discoid lupus erythematosus primarily affects the skin, especially around the nose, and is also known as facial or cutaneous lupus erythematosus. It causes skin crusting, scabbing, and lesions. DLE is more common in hot and sunny climates where exposure to ultraviolet (UV) light can exacerbate the condition. While DLE primarily affects the skin, in some cases, it can progress to involve other parts of the body (WebMD).
Understanding the different types of lupus in dogs is crucial for accurate diagnosis and appropriate treatment. In the following sections, we will explore the symptoms, diagnosis, and treatment options for lupus in dogs.
Symptoms of Canine Lupus
Detecting the symptoms of lupus in dogs is essential for timely diagnosis and treatment. Canine lupus can manifest in various ways, with symptoms differing from dog to dog. In this section, we will explore the common signs and manifestations of lupus in dogs.
Common Signs of Lupus
- Skin lesions: Dogs with lupus may develop skin lesions, which can vary in appearance. These lesions may be red, scaly, crusty, or even ulcerated. They often occur on the face, ears, paws, and other areas exposed to sunlight.
- Enlarged lymph nodes: Lupus can cause the lymph nodes to become swollen and tender to the touch. These enlarged lymph nodes can be detected during a physical examination.
- Fever: Dogs with lupus may experience intermittent or persistent fevers. Monitoring their body temperature can help identify this symptom.
- Decreased appetite and lethargy: Lupus can cause a decrease in appetite and energy levels. Dogs may seem less interested in food and become lethargic or fatigued.
Manifestations of Lupus in Dogs
Lupus can affect various body systems, leading to a range of manifestations. Some of the common manifestations of lupus in dogs include:
- Joint pain and stiffness: Lupus can cause inflammation in the joints, resulting in pain, stiffness, and lameness. Dogs may have difficulty moving or exhibit a reluctance to walk or run.
- Kidney problems: Lupus can affect the kidneys, leading to conditions such as lupus nephritis. Signs of kidney involvement may include increased thirst and urination, loss of appetite, nausea, vomiting, and muscle wasting (Small Door Vet).
- Neurological symptoms: In some cases, lupus can affect the central nervous system, leading to neurological symptoms such as seizures, behavioral changes, and coordination difficulties.
- Dermatological symptoms: Approximately one-third of dogs with lupus will develop dermatological symptoms. These can include skin lesions, hair loss, ulcers around the mouth or genitals, and other changes in the skin’s appearance.
- Anemia: Lupus can cause a decrease in red blood cell count, resulting in anemia. This can lead to symptoms such as weakness, pale gums, and lack of energy.
It’s important to note that the symptoms of lupus can vary in severity and combination. If you suspect your dog may have lupus based on these symptoms, it is crucial to consult with a veterinarian for a proper diagnosis. A veterinarian will conduct a thorough examination and may recommend further diagnostic tests to confirm the presence of lupus.
Understanding the signs and manifestations of lupus in dogs is crucial for early detection and appropriate treatment. If you notice any of these symptoms in your dog, seek veterinary care promptly to ensure the best possible care and management for your furry companion.
Diagnosing Lupus in Dogs
Diagnosing lupus in dogs involves a comprehensive evaluation to rule out other potential causes and identify specific markers of autoimmune conditions. Since lupus can manifest in various ways and affect different organs, diagnosing the disease can be complex and challenging. Veterinarians employ a combination of methods and diagnostic tests to reach a conclusive diagnosis.
Methods for Diagnosing Lupus
To diagnose lupus in dogs, veterinarians utilize a systematic approach that involves:
-
Comprehensive physical examination: The veterinarian will conduct a thorough assessment, considering the dog’s history, clinical signs, and physical symptoms. This helps to identify any specific manifestations associated with lupus and differentiate them from other conditions.
-
Ruling out other potential causes: Since lupus shares symptoms with other diseases, veterinarians must exclude other possible causes before concluding a lupus diagnosis. This process involves eliminating conditions such as infections, other autoimmune disorders, and organ-specific diseases.
-
Bloodwork and laboratory tests: Blood tests, including a complete blood count (CBC) and serum biochemistry panel, are commonly performed. These tests help evaluate the dog’s overall health, detect abnormalities, and assess organ function. Additionally, specialized tests like the Coombs test, ANA test (anti-nuclear antibodies), Lupus erythematosus cell test, and immunofluorescence testing may be used to evaluate autoimmune markers and provide valuable insights into the presence of lupus (PetMD). It should be noted that while the ANA test is important in diagnosing lupus, a positive result alone is not conclusive, as anti-nuclear antibodies can appear due to other autoimmune disorders or infections (Small Door Vet).
-
Urine testing: A urinalysis may be conducted to assess kidney function and detect any signs of kidney involvement, which is common in systemic lupus erythematosus (SLE).
-
Biopsies (if necessary): In cases of suspected discoid lupus erythematosus (DLE), a skin biopsy is typically performed to provide a definitive diagnosis. In some instances of SLE or when other organs are affected, biopsies of those organs may also be necessary to confirm the diagnosis.
Diagnostic Tests for Canine Lupus
Diagnostic tests play a crucial role in identifying and confirming lupus in dogs. These tests may include:
| Diagnostic Test | Purpose |
|---|---|
| Complete Blood Count (CBC) | Evaluates red and white blood cell counts, providing insights into potential anemia and inflammation. |
| Serum Biochemistry Panel | Assesses organ function, including liver and kidney health, which can be affected by lupus. |
| Coombs Test | Detects the presence of autoimmune hemolytic anemia, a common complication of lupus. |
| ANA Test (Anti-Nuclear Antibodies) | Identifies the presence of anti-nuclear antibodies, which are present in approximately 95% of dogs with lupus. However, a positive result does not guarantee a lupus diagnosis, as it can also occur in other autoimmune disorders or infections. |
| Lupus Erythematosus Cell Test | Determines the presence of abnormal cells in the blood, which can indicate SLE. |
| Immunofluorescence Testing | Utilizes fluorescent antibodies to detect specific autoantibodies associated with lupus. |
| Urinalysis | Assesses kidney function and detects any signs of kidney involvement, which is common in SLE. |
| Biopsy | Provides a definitive diagnosis by examining tissue samples from affected areas, such as the skin in the case of DLE, and other organs in the case of SLE. |
The combination of physical examination, ruling out other potential causes, and performing these diagnostic tests helps veterinarians establish a diagnosis of lupus in dogs. It’s important to consult with a veterinarian experienced in autoimmune diseases to ensure accurate diagnosis and appropriate treatment for your furry companion.

By effectively managing lupus symptoms and utilizing appropriate medications, you can help improve your dog’s comfort and overall well-being. Regular communication with your veterinarian and adherence to the prescribed treatment plan are essential for the best possible outcome for your furry companion.
Discoid Lupus Erythematosus (DLE)
Discoid Lupus Erythematosus (DLE) is the most common type of cutaneous lupus in dogs, although it is rare in cats. Dogs affected by DLE develop crusting and scabbing of the skin, usually starting around the nose. Additionally, there is a loss of skin pigmentation in the affected area.
Overview of DLE in Dogs
DLE primarily affects the skin, causing characteristic lesions. The exact cause of DLE is unknown, but it is believed to have an immune-mediated component. Certain breeds, such as Collies, Shetland Sheepdogs, and German Shepherds, are more predisposed to developing DLE. Sun exposure may also play a role in triggering or exacerbating the condition.
To diagnose DLE in dogs, a skin biopsy is usually necessary. A small sample is obtained from a skin lesion using a punch biopsy, and it is sent to a pathologist for analysis to confirm the presence of DLE. Prior to the biopsy, antibiotic therapy may be recommended to minimize the chances of secondary bacterial infections interfering with accurate results.
Diagnosis and Treatment of DLE
The diagnosis and treatment of DLE require a comprehensive approach. Along with the skin biopsy, a thorough physical examination and medical history review are conducted. Diagnostic tests, such as blood work and urinalysis, may also be performed to rule out systemic lupus erythematosus (SLE) or other underlying conditions.
Treatment for DLE aims to suppress the immune system and manage the skin lesions. Topical medications like tacrolimus ointment can be effective in some cases. Systemic medications, such as tetracycline and niacinamide, may also be prescribed. In certain situations, a combination of medications may be needed to achieve the best results. Treatment should be continued until the lesions are fully resolved (VCA Canada).
It’s important to note that dogs with DLE often have secondary bacterial infections in the affected areas. Therefore, antibiotic therapy may be recommended before the skin biopsy to minimize the chances of infection interfering with accurate results.
With appropriate follow-up care and ongoing therapy, the prognosis for dogs with DLE is generally good. Although dogs may experience repeated episodes throughout their lifetime that require treatment, consistent follow-up care can help limit the impact of DLE on their quality of life.
