Decoding the Causes of Jaundice in Dogs

Jaundice in dogs refers to a yellowing of the skin, eyes, and mucus membranes, indicating an issue with the liver or red blood cells. The condition is often a symptom of an underlying problem rather than a disease in itself. In this article, we'll explore the causes, symptoms, diagnosis, and treatment options for jaundice in dogs, helping you understand what might be affecting your pet.

What is Jaundice?

Jaundice is a medical condition characterized by the yellowing of a dog's skin, eyes, and gums. It occurs when there is an excess of bilirubin, a byproduct of red blood cell breakdown, in the bloodstream. Under normal circumstances, the liver processes bilirubin and excretes it through bile. However, when the liver is compromised or when red blood cells break down too quickly, bilirubin can build up in the bloodstream, leading to jaundice.

How Does Jaundice Affect Dogs?

Jaundice can be an indicator of several serious health issues, such as liver disease, hemolytic anemia, or bile duct obstruction. The condition affects the dog’s overall health, causing symptoms like lethargy, weight loss, and digestive issues. In severe cases, jaundice can lead to organ failure if left untreated.

What Causes Jaundice in Dogs？

Several conditions can lead to jaundice in dogs, some of which are more serious than others. These causes are typically related to liver dysfunction, the breakdown of red blood cells, or blockage of bile flow.

• Liver Disease

The liver is responsible for filtering out toxins from the body and processing bilirubin. When the liver becomes diseased or damaged, it may fail to process bilirubin properly, causing it to build up in the bloodstream. Hepatitis, cirrhosis, liver tumors, or toxicity from medications or poisons can all lead to liver dysfunction and jaundice.

• Hemolytic Anemia

Hemolytic anemia occurs when red blood cells are destroyed faster than the body can produce new ones. This can result from autoimmune diseases, infections, or toxins, leading to an overload of bilirubin in the bloodstream and jaundice.

• Gallbladder Disease

The gallbladder stores bile, which helps digest fats. When the gallbladder becomes diseased, infected, or obstructed (such as with gallstones), bile cannot be properly excreted, leading to a buildup of bilirubin in the liver and resulting in jaundice.

• Infections

Infections caused by bacteria, viruses, or parasites can affect the liver or red blood cells, resulting in jaundice. Leptospirosis, canine hepatitis, and tick-borne diseases are some examples of infections that can cause jaundice in dogs.

• Toxins and Poisons

Certain toxins, such as rat poison, pesticides, and medications, can damage the liver and red blood cells, leading to jaundice. Dogs may also develop jaundice after ingesting toxic plants or chemicals.

• Pancreatitis

Pancreatitis, or inflammation of the pancreas, can disrupt the digestive process and interfere with bile production and excretion, leading to jaundice. Dogs with pancreatitis may also experience abdominal pain, vomiting, and loss of appetite.

• Cancer

Tumors in the liver, bile ducts, or pancreas can obstruct bile flow, leading to jaundice. Liver cancer, lymphoma, or pancreatic tumors are common culprits of jaundice in older dogs.

Symptoms of Jaundice in Dogs

• Yellowing of the skin and eye sclera

This is the most obvious symptom of jaundice, which is caused by elevated bilirubin levels, resulting in a yellow coloration of areas such as the skin, conjunctiva of the eyes, skin at the base of the ears, gums, and skin on the abdomen. 

• Mental depression and lethargy

Dogs may exhibit mental lethargy and lethargy due to the fact that jaundice may be accompanied by dysfunction of the liver or other organs, affecting the overall health of the dog. 

• Loss of appetite and weight loss

Jaundice may lead to a loss of appetite in your dog, which in turn may lead to weight loss and a decline in physical condition. 

• Change in urine color (e.g., deep yellow, teal)

When a dog develops jaundice, the amount of bilirubin in the urine increases, resulting in a darker color of urine (e.g., deep yellow, teal). This is due to the liver's inability to properly metabolize bilirubin, allowing it to be excreted through the urine. 

• Digestive symptoms

Digestive complaints such as vomiting, diarrhea, and bloating often accompany jaundice. This is because jaundice may affect the normal functioning of the liver, which in turn affects the normal functioning of the digestive system.

• Other symptoms

Depending on the cause of jaundice, other symptoms may occur, such as increased or decreased body temperature, slowed heartbeat, difficulty breathing, excessive water intake and frequent bowel movements. 

If your dog shows any of these symptoms, it is advisable to take him to the veterinarian for examination and diagnosis so that the cause can be determined early and treated accordingly.

Diagnosing Jaundice in Dogs

To determine the cause of jaundice, a veterinarian will perform a physical examination and may recommend additional diagnostic tests:

Physical Examination

The vet will look for physical signs of jaundice, such as yellowing of the eyes or gums, and assess your dog's overall health.

Blood Tests

A complete blood count (CBC) and biochemical panel can help determine whether the liver is functioning properly and whether the dog is suffering from anemia or other underlying conditions.

Ultrasound and Imaging

Imaging tests, like ultrasound or X-rays, can be used to identify liver diseases, tumors, or bile duct obstructions that might be causing jaundice.

How to Treat Jaundice in Dogs?

The treatment of jaundice in dogs depends on the underlying cause. Jaundice is not a disease per se, but a symptom usually associated with liver disease, bile duct obstruction or red blood cell destruction. Here are some common treatments:

1. Medication

Depending on your dog's specific condition, your veterinarian may prescribe the following medications.

Antibiotics: If the jaundice is caused by an infection, such as hepatitis or cholangitis, antibiotics can help control the infection.
Anti-inflammatory medications: used to reduce inflammation in the liver or bile ducts.
Vitamins and nutritional supplements: such as vitamins B, C, and folic acid, as well as other nutritional supplements to help repair and detoxify the liver.
Liver-protecting medications: such as methionine and silymarin, which protect the liver organs, help protect the liver and bile, and reduce the burden on the liver.

2. Adjustment of diet

During the treatment of jaundice in dogs, it is recommended to feed high-protein, low-fat food and avoid greasy and stimulating food. Vitamin B, vitamin C and folic acid can be given to your dog in moderation to help liver repair and detoxification. If your dog refuses to eat, you can make the food into a paste and slowly instill it with a syringe to avoid choking. You can also feed goat's milk powder, bone broth, chicken broth, fish broth and other nutritious and convenient food for your dog to eat. 

3. Provide enough water and rest

Jaundice can cause toxins to build up in your dog's body, and water can help dilute the toxins and promote excretion. Therefore, make sure your dog has enough water and provide a quiet resting environment so that your dog can rest adequately. 

4. Treatment of Causes

If jaundice is caused by a specific disease, such as gallstones, tumors or parasitic infections, surgery or other targeted treatment may be required.

During the course of treatment, the dog's condition needs to be closely monitored and the treatment plan adjusted according to the veterinarian's advice. At the same time, care should be taken to keep the dog's living environment clean and avoid contact with other sick dogs to avoid infection. 

How to Take Care of Dogs During Jaundice?

I. Dietary care

1.Balanced and appropriate nutrition

Choose high-protein, low-fat foods: for example, lean chicken, eggs (egg white-based), fish and other foods rich in high-quality protein. These foods help to replenish your dog's nutrients while reducing the burden on the liver.

Increase intake of high-vitamin foods: like fresh vegetables (e.g. broccoli, carrots) and fruits (e.g. apples, bananas), which can provide a variety of vitamins such as Vitamin C and B vitamins, which can help boost your dog's immunity and contribute to the recovery of liver function.

Copper control: Avoid feeding copper-rich foods, such as liver foods, as too much copper may aggravate the liver.

2.Adjustment of feeding method

Small amount of food: Divide the daily amount of food into several feedings, and reduce the amount of each feeding appropriately. This will reduce the burden on your dog's digestive system and prevent vomiting and other discomforts caused by eating too much at once.

Hydrate: Make sure your dog has fresh, clean water to drink at all times. Jaundice can cause a buildup of toxins in your dog's body, and water helps dilute the toxins and promote excretion. If your dog is not very active in drinking water, try using a pet-specific waterer or adding a small amount of broth to the water to entice your dog to drink.

II. Condition monitoring and care

1.Observe changes in symptoms

Skin and eye color: Pay close attention to changes in the shade of yellow of your dog's skin and eye sclera. If the yellow color gradually becomes lighter, it may indicate that the condition is improving; on the contrary, if the yellow color deepens, the condition may worsen.
Mental status and appetite: Pay attention to your dog's mental status, such as whether it is still lethargic, depressed, or if it shows signs of mental improvement. At the same time, observe the dog's appetite and record the amount of food eaten each day. If the dog's appetite improves, it is also a sign of improvement.
Urine and feces: Observe whether the color of your dog's urine is still dark yellow and whether the color of the feces has become lighter. Under normal circumstances, with treatment and recovery, the color of urine will gradually become lighter and the color of feces will return to normal.

2.Follow your doctor's instructions for care

Give medication on time: Give your dog medication exactly as your veterinarian instructs, including the type of medication, dosage, and time of administration. Do not increase or decrease the dosage or stop the medication on your own.
Regular review: Take your dog to the hospital for regular review according to your veterinarian's arrangement, such as conducting blood tests and liver function tests, etc., so that the treatment plan can be adjusted in time.

When to See a Vet
