Causes
The kidneys are essential organs responsible for filtering waste products from the blood, regulating fluid balance, and maintaining electrolyte balanceThe electrolyte balance refers to the balance of electrolytes in the body, which is essential for many physiological processes. Disturbances in the electrolyte balance can lead to serious health problems.. In chronic nephritis, the kidney tissue is continuously inflamed, leading to damage to the kidney structures, especially the nephrons. Nephrons are the functional units of the kidney responsible for the filtration and purification of the blood.
The causes of 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. nephritis can be diverse. One of the most common triggers is a persistentPersistent means lasting or continuing for an extended period. In veterinary medicine, it can refer to chronic diseases or symptoms that do not subside. bacterial 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. that has not been completely treated. These infections can ascend from the urinary tract and reach the kidneys. Similarly, certain 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., in which the immune systemThe immune system is the body's defense system against infectious agents such as bacteria, viruses, fungi, and parasites.

Symptoms
The symptoms of 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. nephritis in dogs are often insidious and easily overlooked in the early stages. The first signs often include frequent drinking and urination, as the body tries to compensate for excess waste products that the kidneys can no longer effectively filter.
As the disease progresses, loss of appetite, Weight loss, Vomiting, and DiarrheaDiarrhea refers to the condition of frequent, watery bowel movements, which can be a sign of infections, digestive disorders, or other health problems. may occur. The dogs appear lethargic and weak, which is due to the accumulation of toxins in the body and the loss of important nutrients. In severe cases, there may be bad breath and ulcers in the mouth, indicating an increased concentration of toxins in the blood.
EdemaAn edema is a buildup of fluid in the body’s tissues, leading to Swelling. Edema can be localized or generalized and is often a sign of an underlying condition., i.e. Swelling in various parts of the body, can also occur because the kidneys are no longer able to regulate fluid balance. This can be particularly visible in the face, legs, or abdomenThe abdomen, also known as the abdominal cavity, is the part of the body located between the rib cage and the pelvis. It houses several important organs, including the stomach, liver, kidneys, intestines, and spleen..
Diagnosis
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. of 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. nephritis usually begins with a thorough 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. and clinical examination by the veterinarian. Blood tests are crucial to assess kidney function. Elevated levels of creatinineCreatinine is a waste product that results from the breakdown of creatine, a chemical compound that provides energy in the muscles. The concentration of creatinine in the blood and urine is an important indicator of kidney function. and urea in the blood are typical indicators of kidney failureRenal failure is a condition in which the kidneys can no longer adequately perform their function of filtering and excreting waste products from the blood. It can be acute or chronic and requires immediate medical treatment..
In addition, urine tests can be performed to check for proteinuriaProteinuria is the presence of excessive protein in the urine, often indicating kidney dysfunction. It can be an early sign of kidney disease in dogs and cats. (the presence of protein in the urine) and the specific gravity of the urine, which provides information about the kidneys’ ability to concentrate. Imaging procedures such as 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. or X-rays can help detect structural changes or abnormalities in the kidneys.
In some cases, a kidney 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.

A special kidney diet that is low in proteinProteins are large molecules made up of amino acids and play an essential role in almost all biological processes. They are necessary for building body tissue, the function of the immune system, and as enzymes for metabolic reactions. and phosphorusPhosphorus is a vital mineral found in bones and teeth, playing a central role in energy metabolism and DNA. A balanced phosphorus to calcium ratio is essential for the health of dogs and cats. can help relieve the kidneys and reduce the formation of toxins.
Medications such as ACE inhibitors can be used to lower blood pressure and support kidney function. If a bacterial 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 are needed to fight the pathogens. 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 help reduce inflammation.
In advanced cases, fluid therapyTherapy refers to the treatment of diseases or disorders with the aim of alleviating symptoms, promoting healing, or improving quality of life. Therapies can be medicinal, surgical, or through other medical interventions. may be necessary to regulate fluid balance and support the eliminationElimination refers to the process by which waste products and toxins are removed from the body. This includes excretion via the kidneys (urine), intestines (stool), lungs (breath), and skin. of toxins. This treatment can be administered either intravenously or subcutaneously, depending on the dog’s condition.
Prognosis and follow-up care
The prognosis for dogs with 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. nephritis depends on various factors, including the stage of the disease at the time of 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., the underlying cause, and the response to treatment. In the early stages, appropriate treatment can significantly improve the quality of life and slow the progressionProgression refers to the advancement or worsening of a disease over time. It describes an increase in the severity or extent of the disease symptoms. of the disease.
Unfortunately, a complete cure is rare, as damage to the kidneys that has already occurred cannot be reversed. In advanced stages, the prognosis is often unfavorable, and treatment focuses on relieving symptoms and supporting kidney function.
Regular monitoring by the veterinarian and adjustments to treatment are crucial to achieve the best possible outcome and maximize the dog’s life expectancy.
Prevention
PreventionPrevention includes measures taken to prevent diseases or injuries. In veterinary medicine, this includes vaccinations, parasite control, and health monitoring. of 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. nephritis in dogs begins with minimizing risk factors and promoting good kidney health. Regular veterinary check-ups are important to detect early signs of kidney disease and take action in time. A balanced diet specifically tailored to the dog’s needs can help protect the kidneys.
It is important to treat urinary tract infections early to prevent bacteriaBacteria are microscopic, single-celled organisms that exist in almost every environment on Earth. Some types of bacteria are beneficial or even essential to life, while others can cause disease. from ascending to the kidneys. Dogs should also be protected from contact with potentially kidney-damaging toxins by keeping them away from dangerous substances such as certain plants, chemicals, and medications.
For breeds that are genetically predisposed, genetic counseling may be useful to assess the risk of developing the disease. In such cases, a targeted breeding strategy can help reduce the prevalence of kidney disease.
Outlook on current research
Research into Chronic Nephritis in dogs is a dynamic and continuously growing field. Scientists are striving to identify the genetic factors that contribute to susceptibility to this disease. There is evidence that certain breeds are more susceptible due to genetic predispositions. For example, studies in breeds such as the Dalmatian, Bull Terrier, and Shih Tzu have shown a higher incidenceIncidence refers to the number of new cases of a disease or condition that occur within a specific time period in a specific population group.
