What Does Liver Disease In Dogs Mean?

Liver disease in dogs can take many forms, from inflammation (hepatitis) to genetic disorders (such as copper storage disease) or tumors. Regardless of the cause, when the liver is damaged, it cannot perform its vital functions effectively. Symptoms may be vague at first but often progress to loss of appetite, vomiting, weight loss, increased thirst, lethargy and, in severe cases, jaundice or neurological symptoms (hepatic encephalopathy).

Diagnosis is made by a veterinarian through blood tests, urine tests, ultrasound and often a liver biopsy for a definitive diagnosis. A correct diagnosis is crucial to being able to choose the right food for liver disease in dogs and a treatment plan.

How Special Foods Support the Liver

Liver disease foods are scientifically formulated to:

• **Reduce Liver Stress:** Through controlled levels of high-quality, easily digestible protein. This minimizes the production of ammonia, which a damaged liver has difficulty detoxifying and which can lead to neurological problems.
• **Reduce Copper Accumulation:** With low copper levels to prevent further liver damage, especially important for breeds predisposed to copper storage disease.
• **Provide Sufficient Energy:** High content of easily digestible carbohydrates and fat ensures that the dog receives sufficient energy without overloading the liver with protein metabolism.
• **Support Liver Cells:** Enriched with antioxidants (Vitamin E, C, SAMe, Milk Thistle) to protect liver cells from oxidative stress and promote regeneration.
• **Control Fluid Retention:** Moderately reduced sodium content to reduce the risk of fluid retention (ascites).
• **Optimize Nutrient Absorption:** Added B vitamins and zinc to compensate for any deficiencies and support liver metabolism.

These diets are part of the veterinary food category and are essential for managing liver disease effectively.

Important Complementary Measures

In addition to diet, several other measures are necessary in the management of liver disease:

1. **Medical Treatment:** The veterinarian may prescribe medications such as antibiotics, corticosteroids (for inflammation), ursodeoxycholic acid (for bile flow), lactulose (against ammonia), or copper-binding agents.
2. **Supplements:** In consultation with a veterinarian, supportive supplements such as SAMe, milk thistle, and additional vitamins/minerals may be beneficial.
3. **Fluid and Electrolyte Balance:** Ensure good hydration, especially in case of vomiting or diarrhea.
4. **Management of Complications:** Treat symptoms such as fluid retention (ascites) with diuretics or by fluid resuscitation. Manage neurological symptoms with lactulose and a protein-controlled diet.
5. **Regular Veterinary Visits:** Frequent follow-ups with blood tests and possible ultrasound are essential to monitor liver function and adjust treatment.
6. **Overall Health Assessment:** Liver disease can affect and be related to other health problems. It is important to consider the dog's overall health, including skin health , gastrointestinal health , diabetes control , kidney disease , urinary tract problems , joint and movement health , stress and nervousness , dental health , and heart disease , as all of these can affect each other. Weight control for dogs is also of great importance.

Frequently Asked Questions about Food for Liver Disease Dogs

Here we answer some of the most frequent questions we receive regarding food for dogs with liver disease.

What is liver disease in dogs and what are the most common causes?

The liver is one of the most vital organs in the dog's body, responsible for over 1,500 different functions. It plays a central role in metabolism, detoxification, protein production, bile production, and storage of vitamins and minerals. When the liver becomes diseased, the entire body's function can be seriously affected. Liver disease in dogs can vary in severity and type, from acute to chronic conditions. Common types of liver disease: - Hepatitis (inflammation of the liver): Can be acute or chronic, infectious or non-infectious. - Cirrhosis of the liver: The end stage of chronic liver disease, where liver tissue is irreversibly damaged and replaced by scar tissue. - Portosystemic shunt (PSS): A congenital or acquired vascular malformation in which blood is shunted past the liver instead of passing through it for detoxification. - Liver tumors: Can be benign or malignant. - Copper poisoning/Copper storage disease: Some dog breeds (e.g. Bedlington terrier, West Highland White terrier, Dobermann) have a genetic predisposition to store too much copper in the liver, leading to progressive liver damage. - Acute liver damage: Can be caused by toxins (e.g. certain fungi, drugs), infections or trauma. - Cholangiohepatitis: Inflammation of the bile ducts and liver. Causes of liver disease in dogs: The causes are many and sometimes complex, but the most common include: - Infections: Bacterial (e.g. leptospirosis), viral, parasitic (e.g. liver flukes) or fungal infections. - Toxins: Ingestion of toxic substances such as certain plants, drugs (e.g. paracetamol overdose), chemicals, moldy food or algae. - Genetic factors: Some breeds are predisposed to specific liver diseases (e.g. copper storage disease in Bedlington terriers). - Medications: Long-term use of certain medications (e.g. corticosteroids, some anticonvulsants) can put a strain on the liver. - Other underlying diseases: Diseases such as pancreatitis, diabetes, or heart disease can affect the liver indirectly. - Trauma: Injuries to the abdomen can cause liver damage. Symptoms of liver disease in dogs: Symptoms can be vague and nonspecific in the early stages, as the liver has a large reserve capacity. Once symptoms appear, they may include: - Loss of appetite and weight loss. - Vomiting and diarrhea. - Increased thirst and urination. - Lethargy and decreased energy. - Jaundice (icterus): Yellowish discoloration of the skin, whites of the eyes, and mucous membranes, caused by the accumulation of bilirubin. - Increased abdominal size (ascites): Fluid accumulation in the abdomen. - Neurological symptoms (hepatic encephalopathy): Disorientation, drooling, seizures, behavioral changes (e.g., head-butting), as a result of toxins (especially ammonia) accumulating in the blood and affecting the brain. - Dark urine and light stools. - Bleeding tendency: The liver produces clotting factors. Diagnosis of liver disease in dogs: The diagnosis is made by a veterinarian through a combination of: - Blood tests: Elevated liver enzymes (ALT, ALP), elevated bilirubin, low albumin, altered coagulation values, elevated bile acids. - Urine test: May show changes. - Ultrasound: To visualize the size, structure, and possible changes or tumors of the liver. - X-ray: Can provide information about the size and shape of the liver. - Liver biopsy: Often necessary for a definitive diagnosis and to determine the type of liver disease and the degree of damage. This is the gold standard. - Other tests: E.g., copper biopsy in suspected copper storage disease. A dog food for liver disease is a fundamental part of the treatment to support liver function and reduce its workload, but it must always be complemented by a veterinary diagnosis and possible medical treatment.

What nutrients are crucial in food for liver disease dogs, and why?

A customized diet for liver disease dogs is a cornerstone of treatment and aims to reduce the strain on the damaged liver while providing enough nutrients to support regeneration and prevent nutritional deficiencies. The composition of the diet must be carefully balanced to achieve these goals. Here are the most important nutrients and why they are crucial: 1. Controlled, High-Quality Protein: - Why: Protein is essential for cell repair and maintenance of muscle mass. However, a damaged liver can have difficulty metabolizing byproducts of protein (especially ammonia), which can lead to hepatic encephalopathy (neurological symptoms). - Solution: Diets for liver disease contain carefully selected, easily digestible protein sources (e.g. vegetable proteins such as soy, dairy proteins such as casein, or specific animal proteins) in a controlled amount. The goal is to provide enough protein to avoid muscle wasting without overloading the liver. Some diets may have a higher protein content if liver function is still good, while those with hepatic encephalopathy require more stringent protein restriction. 2. Low Copper: - Why: Copper is normally stored in the liver and excreted via the bile. In liver disease, especially chronic hepatitis or genetic storage diseases, copper can accumulate to toxic levels and cause further liver damage. - Solution: These diets have a significantly reduced copper content to prevent excessive accumulation and facilitate excretion. 3. Controlled Sodium: - Why: Too much sodium can contribute to fluid retention (ascites, edema) in the abdomen or other parts of the body, which is common in liver disease. - Solution: Sodium is moderately reduced to minimize fluid retention. 4. High Energy from Carbohydrates and Fat: - Why: Since protein intake may be limited, energy needs must be met from other sources to prevent the body from breaking down protein for energy (which creates more ammonia). - Solution: These feeds are often energy dense, with an increased proportion of easily digestible carbohydrates and fat. Fat is a concentrated source of energy and generates fewer toxic by-products than protein. Easily digestible fats (e.g. MCT oils) can be beneficial. 5. Added Vitamins and Minerals: - Why: A diseased liver may have difficulty storing and metabolizing vitamins (especially fat-soluble A, D, E, K) and B vitamins. In addition, increased urination and decreased bile production can lead to deficiencies. - Solution: Fortification with water-soluble B vitamins, vitamins E and K, and zinc (which can inhibit copper absorption and is an antioxidant). Iron and manganese can be controlled. 6. Antioxidants: - Why: A damaged liver often experiences increased oxidative stress. - Solution: Added antioxidants such as vitamins E, C, selenium, taurine and S-adenosylmethionine (SAMe) help protect liver cells and support their function. 7. High Fiber Content (Soluble Fiber): - Why: Soluble fiber (e.g. from psyllium) can bind ammonia and other toxins in the intestine, preventing absorption and reducing the liver's workload. They can also help regulate intestinal transit. A food for liver disease dogs is a specialized diet and is part of veterinary food. It is crucial that it is prescribed and followed up by a veterinarian, as an incorrect diet can worsen the condition. At Zoostar.se you will find these customized foods that can give your dog the best conditions to manage their liver disease.

How to manage liver disease in dogs beyond diet?

Managing liver disease in dogs is complex and requires a multifaceted approach, of which the diet with food for liver disease dogs is a central part, but far from the only one. A close dialogue and collaboration with your veterinarian is essential to optimize your dog's quality of life and slow down the progression of the disease. Here are other important measures: 1. Medical Treatment: - Antibiotics: If there are signs of bacterial infections in the liver or bile ducts. - Corticosteroids (cortisone): In inflammatory liver diseases (hepatitis) to suppress inflammation. Use with caution. - Ursodeoxycholic acid (UDCA): A bile salt that helps improve bile flow and protect liver cells. - Lactulose: In hepatic encephalopathy to reduce the absorption of ammonia from the intestine. It acts as a laxative and lowers the pH of the intestine. - Copper binding agents: In copper storage disease to excrete excess copper (e.g. D-penicillamine, Trientine). 2. Supportive Supplements (always in consultation with a veterinarian): - S-Adenosylmethionine (SAMe): An important antioxidant and precursor to glutathione, which is crucial for the liver's detoxification processes. May improve liver function and protect liver cells. - Milk Thistle (Silymarin): An antioxidant and anti-inflammatory substance that can support liver health. - Vitamins E & C: Additional antioxidants. - B vitamins: To compensate for reduced storage in the liver. - Zinc: Can help reduce copper absorption and is important for liver function. 3. Fluid and Electrolyte Balance: - In case of vomiting/diarrhea: Ensure adequate fluid intake and correct any electrolyte disturbances, which may require intravenous fluids. 4. Management of Ascites (Fluid in the abdomen): - Diuretics (water pills): To reduce fluid accumulation in the abdomen. - Paracentesis: In severe cases, the vet may need to drain the fluid from the abdomen with a needle. - Dietary sodium restriction: An important part of the diet to reduce fluid retention. 5. Control of Bleeding Tendency: - Vitamin K: If the liver does not produce enough clotting factors. 6. Management of Hepatic Encephalopathy: - Protein-controlled diet: As mentioned, a diet with controlled levels of high-quality protein is crucial. - Lactulose: To reduce ammonia in the gut. - Antibiotics: Some antibiotics can be used to reduce ammonia-producing bacteria in the gut. 7. Regular Follow-up and Monitoring: - Blood tests: Frequent follow-up with blood tests (liver enzymes, bile acids, coagulation values) to assess liver function and adjust treatment. - Ultrasound: To monitor the condition of the liver. - Weight control: Maintain a healthy weight. Other related health problems may also be affected. For example, dogs with liver disease may need extra attention to skin health and gastrointestinal health. Sometimes they can also be linked to diabetes, kidney disease, urinary tract problems, joint and movement health, stress and nervousness, dental health or heart disease. Quality of life: The goal is always to maximize your dog's quality of life. This may mean balancing the intensity of treatment with the dog's well-being. Having a dog with liver disease requires patience and commitment. By following your veterinarian's advice, feeding the recommended food for liver disease dogs from Zoostar.se and paying attention to your dog's symptoms, you can give your best friend the best possible care.
