The most common symptoms of panniculitis in dogs are the formation of lumps or swelling under the skin. These lumps can feel soft or firm and vary in size. They are often painful and may enlarge or harden over time.
In addition to the palpable lumps, dogs with panniculitis may have hair loss and redness at the affected sites. In some cases, ulcers and purulentPurulent refers to pus or the production of pus, which may indicate a bacterial infection. Purulent inflammatory conditions are often painful and may have significant swelling and redness. discharge may occur if the inflamed areas open.
Systemic symptoms, such as fever, lethargy, and loss of appetite, may also occur, especially if the inflammation is caused by an infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease. or a systemic disease.
Diagnosis
The diagnosis of panniculitis begins with a thorough clinical examination by a veterinarian. The veterinarian will examine the dog’s skin for lumps, swelling, and other signs of inflammation. A complete historyThe medical history is the systematic collection of a patient's medical history through questioning. It includes information about previous illnesses, treatments, allergies, and lifestyle habits., including information about previous injuries or illnesses, can also be helpful.
To confirm the diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients., a fine needle aspiration or biopsyA biopsy is a medical procedure in which a small amount of tissue is removed from the body to be examined under a microscope for signs of disease.

Additional tests, such as blood tests, X-rays, or ultrasoundUltrasound refers to sound waves that are above the hearing threshold of the human ear. In medicine, ultrasound is used for diagnostic imaging procedures to visualize internal organs, tissues, and blood flow., may be necessary to rule out or identify underlying systemic diseases.
Therapy
The treatment of panniculitis depends on the underlying cause. If an infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease. is present, antibiotics or antifungals may be prescribed to combat the pathogens. For autoimmune causes, immunosuppressiveImmunosuppressive agents are medications or substances that specifically suppress the activity of the immune system. They are used in dogs and cats to treat autoimmune diseases, allergies, and to prevent rejection reactions after transplants. drugs may be necessary to control the immune responseAn immune response is the immune system's reaction to foreign substances (antigens), such as microorganisms or proteins. It involves a series of processes aimed at recognizing, fighting, and eliminating these antigens..
In cases where the panniculitis is caused by foreign bodies or traumatic injuries, surgical removal of the affected areas may be necessary. Removal of necrotic tissue and cleaning of the wound can help promote healing.
Pain relievers and anti-inflammatory drugsAnti-inflammatory drugs are medications that reduce inflammation. They can be divided into nonsteroidal anti-inflammatory drugs (NSAIDs) and corticosteroids and are used in dogs and cats to reduce Inflammatory conditions and Pain. can be used to relieve the symptoms and improve the dog’s comfort. Close monitoring by the veterinarian is important to assess the success of the treatment and make adjustments if necessary.
Prognosis and follow-up care

In some cases, the disease can become chronicChronic refers to a condition or disease that is long-lasting or permanent. Chronic diseases often develop slowly and can lead to persistent or recurring health problems over time. and recurrentRecurrent refers to a disease that repeatedly returns or worsens after a temporary remission or improvement. flare-ups require continuous medical care.
Prevention
The prevention of panniculitis can be difficult because the causes are diverse. Good general care and hygiene can help minimize the risk of infections and injuries. Regular veterinary examinations can help detect and treat underlying diseases early.
For dogs with known autoimmune diseasesAutoimmune diseases are conditions in which the immune system mistakenly attacks the body's own cells or tissues as if they were foreign substances. Examples in dogs and cats include autoimmune hemolytic anemia and systemic lupus erythematosus. or a tendency to panniculitis, a special diet or adapted management may be required to support immune function and reduce inflammation.
It is also important to minimize potential hazards in the dog’s environment to avoid injuries that could triggerA trigger is a stimulus that elicits a specific reaction or state. In veterinary medicine, this can refer to emotional responses, such as fear or aggression, or medical conditions, such as seizures in dogs and cats. panniculitis. Monitoring the dog for signs of skin changes and early veterinary advice can be crucial to effectively manage the disease.
Outlook on current research
Research on panniculitis in dogs is a continuously evolving field that focuses on identifying the underlying causes, effective diagnostic methods, and innovative treatment options. Current studies are investigating the genetic factors that could lead to an increased susceptibility to panniculitis. Some research suggests that certain dog breeds may be genetically predisposed, suggesting that a genetic component needs to be considered.
Another important area of research is the role of the immune systemThe immune system is the body's defense system against infectious agents such as bacteria, viruses, fungi, and parasites.
