Lupoid dermatosis in German Shorthaired Pointers is a skin condition that's often misunderstood. It's a complex condition that affects the skin's immune system, leading to a range of symptoms.
German Shorthaired Pointers are a breed that's particularly prone to lupoid dermatosis, with studies showing that up to 40% of the breed can be affected.
The condition typically starts with small, itchy lesions on the skin, which can eventually spread and become more severe.

What is Lupoid Dermatosis?
Lupoid dermatosis is a serious degenerative disease that affects German Shorthaired Pointers. It's a condition that can progress rapidly, so it's essential to catch it early.
The disease is usually noticed before a dog is six months old, when the skin starts getting crusty with scaling on the head, face, and torso. This can be a sign that something is wrong, and it's crucial to take your dog to the vet right away.
Lupoid dermatosis can cause a range of symptoms, including itchy skin, swollen and sore joints, and even kidney failure. If left untreated, the condition can spread to the lymph nodes, spleen, tonsils, and adenoids, leading to a poor quality of life for your dog.
In many cases, renal failure occurs within the first year of life, and sadly, many dogs are euthanized within the first two years due to the painful infections and renal failure.

German Shorthaired Pointer and Lupoid Dermatosis
The German Shorthaired Pointer is a breed that can be prone to lupoid dermatosis, a painful and itchy skin condition. This inherited condition can appear as early as 8 weeks of age.
Signs of lupoid dermatosis in German Shorthaired Pointers include dry, flaky skin, painful crusts, and lesions on the face, back, and ears. These lesions can lead to bacterial or fungal infections.
The condition can also cause hair loss and joint pain, which may lead to lameness. In severe cases, lupoid dermatosis can even cause renal failure.
Treatment for lupoid dermatosis in German Shorthaired Pointers focuses on relieving the discomfort caused by the condition, as there is no cure.
Symptoms and Diagnosis
Lupoid dermatosis in German Shorthaired Pointers can be a challenging condition to diagnose, but it's essential to catch it early to provide the best possible care for your furry friend.
The symptoms of lupoid dermatosis are varied and can affect each dog differently. In some cases, the disease only affects the skin, but most of the time it will progress to stage II, in which the joints and kidneys are affected as well.
Stage I symptoms include scaly skin with lesions and blisters starting on the head and spreading to the rest of the body, including the anus and inside the mouth. The skin may also become thickened, and there may be changes in pigment, hair loss, stiff legs, joint pain, swelling of joints, weakness, and weakened reflexes.
Stage II symptoms are more serious and can include fever, swollen lymph nodes, and kidney failure. These symptoms require immediate veterinary attention.
A veterinarian will likely suspect lupoid dermatosis in a German Shorthaired Pointer with a skin condition, but they will always do a complete body assessment, including a comprehensive physical examination. This will include vital signs, overall coat condition, lameness evaluation, auscultation, and palpation.
To confirm the diagnosis, laboratory tests such as a chemistry profile, blood count, and bacterial and fungal cultures may be performed. Skin scrapings and biopsies are also essential in detecting the condition, as they can reveal the presence of edema, hyperkeratosis, and degeneration of skin cells.
The veterinarian may also use indirect immunofluorescence to detect IgG of the basement membranes of the skin and sebaceous glands. An antinuclear antibody (AA) test is needed to confirm that this is an autoimmune disorder. Radiographs (x-rays) and ultrasound may be used to determine if there is any kidney involvement, and an MRI or CT scan can also be helpful in this case.
Here are the stages of lupoid dermatosis and their corresponding symptoms:
Treatment and Recovery
Lupoid dermatosis is considered an untreatable disease, but drugs can be used to slow its progression.
Cephalexin is a common drug used for treating lupoid dermatosis, but hydroxychloroquine has been found to be more effective.
Adalimumab has also shown effectiveness in treating the disease, and prednisone is given to decrease inflammation.
Antibiotics are prescribed to prevent infections, and shampoo containing chlorhexidine may be suggested to help manage skin symptoms.
NSAIDs are used to help with pain and inflammation of joints.
In some cases, the disease can go into recession completely, but many dogs are euthanized before their fifth year due to complications or kidney failure.
It's essential to continue regular veterinary check-ups to assess your dog's quality of life and perform laboratory tests as needed.
Some medications require frequent kidney and liver function tests.
If your dog is diagnosed with lupoid dermatosis, it's crucial to work closely with your veterinarian to develop a treatment plan.
Here are some common medications used to treat lupoid dermatosis:
- Cephalexin
- Hydroxychloroquine
- Adalimumab
- Prednisone
- Antibiotics
- Shampoo containing chlorhexidine
- NSAIDs
Skin Conditions and Testing
Lupoid dermatosis is a skin condition that affects German Shorthaired Pointers, and it's essential to understand the testing and treatment options available.
Most pooches diagnosed with lupoid dermatosis are euthanized by 4 years of age due to the pain and recurrent skin infections it causes.
The only definitive way to diagnose this condition is through a combination of blood tests, skin scrapings, and skin biopsies, as well as bacterial and fungal cultures of the skin.
Your vet can formulate a treatment plan that may include medicated shampoos and steroids to treat the skin.
If your German Shorthaired Pointer is diagnosed with lupoid dermatosis, it's crucial not to breed them, as carriers of the mutated gene can pass it on to their offspring.
A cheek swab DNA test is available through the University of Pennsylvania to detect the mutated gene.
Treatment with hydroxychloroquine may halt the progression of the disease if a pup is diagnosed at an early age.
The Lonestar German Shorthaired Pointer Club offers a marker test for lupoid dermatosis, and Purina has focused research on this condition in German Shorthaired Pointers.

Variants and General Information
Lupoid dermatosis is a type of autosomal recessive condition that affects the German shorthaired pointer breed.
The condition results from a genetic mutation that is specific to this breed, and it's not a guarantee that a pup will suffer from it just because they carry the mutated gene.
In order to develop the disease, a pup must inherit a mutated gene from each of their parents, which means genetic testing is recommended to prevent two carriers of the gene from mating.
About 25 percent of the offspring would suffer from the disease if two carriers of the gene were to mate, making genetic testing a crucial step in preventing the condition.
DNA testing is not perfect but can give you an idea of whether or not your pup is a carrier of the disease.
