Understanding Jaundice in Dogs
Jaundice in dogs, also known as icterus, is a condition characterized by the yellowing discoloration of a dog’s gums, eyes, skin, and blood. This yellow pigment is the result of an increased accumulation of bilirubin, a waste product produced during the breakdown of red blood cells. Hyperbilirubinemia, or elevated levels of bilirubin in the blood, is a symptom of a severe underlying condition and can be a medical emergency (PetMD).
Definition and Symptoms
Jaundice manifests as a yellowish hue on the skin, gums, white area of the eyes, and ear flaps of dogs. The intensity of the yellow discoloration may vary depending on the dog’s fur, gums, or skin pigment. While jaundice itself is not a disease, it is an indicator of an underlying health issue.
In addition to the visible yellowing, other symptoms that may accompany jaundice in dogs include:
- Dark urine
- Pale stools
- Lethargy
- Loss of appetite
- Vomiting
- Abdominal pain
- Weight loss
- Swelling or discomfort in the abdomen
If you notice any of these symptoms, it is important to seek veterinary attention promptly to determine the cause and initiate appropriate treatment.
Causes of Jaundice
Jaundice in dogs can occur due to various factors. It is often a result of an increase in bilirubin production associated with the damage or destruction of red blood cells, or a decrease in its removal from the body. Conditions affecting the liver, gallbladder, or red blood cells can significantly impact bilirubin metabolism, leading to jaundice (PetMD).
Common causes of jaundice in dogs include:
- Liver disease, such as hepatitis or cirrhosis
- Gallbladder disease, including gallstones or cholecystitis
- Inflammation of the bile ducts, known as cholangitis
- Infections, such as leptospirosis or canine infectious hepatitis
- Immune-mediated diseases affecting the liver, such as canine immune-mediated cholangitis
- Certain medications or toxins that can damage the liver
Determining the underlying cause of jaundice is crucial for appropriate treatment. Veterinary evaluation, including blood tests and examinations, can help identify the specific condition causing jaundice in your dog.

Understanding the definition, symptoms, and causes of jaundice in dogs is essential for recognizing this condition and seeking timely veterinary care. Early detection and prompt treatment can improve the prognosis and overall well-being of your furry companion.
Diagnosing Jaundice in Dogs
When it comes to diagnosing jaundice in dogs, veterinarians employ various methods to identify the underlying cause of this condition. Diagnostics play a crucial role in determining the appropriate treatment approach for the affected dog. Two commonly used diagnostic techniques for jaundice in dogs are blood tests and examinations, as well as ultrasound and biopsy.
Blood Tests and Examinations
To assess liver function and identify potential causes of jaundice, veterinarians often conduct blood tests and examinations. These tests help measure the levels of bilirubin in the blood and determine whether it is unconjugated (related to red blood cell breakdown) or conjugated (related to liver injury) (Cleveland Clinic). Elevated levels of bilirubin indicate liver dysfunction or other underlying conditions that may be contributing to jaundice.
In addition to bilirubin levels, veterinarians may analyze other liver enzymes and markers through a biochemistry profile blood test. This includes tests such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and total bilirubin. These tests help evaluate liver function and identify specific liver diseases.
During the examination, veterinarians may also look for other signs of liver disease, such as changes in appetite, weight loss, vomiting, or abdominal pain. These additional assessments aid in determining the underlying cause of the jaundice and guiding further diagnostic steps.
Ultrasound and Biopsy
In cases where blood tests and examinations do not provide a definitive diagnosis, veterinarians may recommend additional imaging techniques like ultrasound and biopsy to further evaluate the liver and surrounding organs.
Ultrasound is a non-invasive imaging method that uses sound waves to create detailed images of the liver, gall bladder, and bile ducts. It helps identify any abnormalities, such as gallstones or tumors, that may be contributing to the jaundice. Ultrasound can provide valuable information about the structure and condition of the liver, aiding in the diagnostic process.
In some cases, a liver biopsy may be necessary to obtain a more accurate diagnosis. A biopsy involves the collection of a small tissue sample from the liver for microscopic examination. It helps determine the severity and type of liver disease, such as hepatitis or cholangiohepatitis (Guilford Jamestown Veterinary Hospital). Biopsies can be performed using different techniques, including fine-needle aspiration or surgical biopsy.
By combining the results of blood tests, examinations, ultrasound imaging, and liver biopsies, veterinarians can accurately diagnose the cause of jaundice in dogs. This comprehensive approach enables them to tailor the treatment plan to address the underlying condition responsible for the jaundice in order to improve the dog’s overall health and well-being.
Treatment Options for Jaundice
When it comes to treating jaundice in dogs, the primary focus is on addressing the underlying causes and providing supportive care. Treatment options may vary depending on the specific condition causing jaundice. It is essential to consult with a veterinarian for an accurate diagnosis and tailored treatment plan.
Addressing Underlying Causes
Identifying and treating the underlying cause of jaundice is crucial for effective management. Causes of jaundice in dogs can range from immune-mediated hemolytic anemia, infections, toxins, cancer, liver failure, gallbladder disease, copper-associated hepatopathy, to portosystemic shunts. Diagnostic tests, including blood tests and examinations, may be conducted to determine the specific cause.
Once the underlying cause is identified, treatment will be directed towards addressing that condition. For example, if the jaundice is caused by liver infection or inflammation, appropriate medications and therapies will be prescribed to target the infection or reduce inflammation. In some cases, surgery may be necessary to address certain conditions, such as gallbladder disease or portosystemic shunts.
Medications and Therapies
In addition to treating the underlying cause, medications and supportive therapies may be used to manage jaundice symptoms and promote liver health. Medications prescribed for liver disease may help improve liver function and reduce inflammation (WagWalking). In cases where cancer is the underlying cause, chemotherapy may be considered as a treatment option.
Supportive therapies may also be recommended to aid in the recovery and overall well-being of the dog. These may include dietary changes, such as a liver-friendly diet, to support liver function and promote healing. Your veterinarian may also suggest supplements or medications to support liver health and reduce oxidative stress.
It is important to note that the treatment approach for jaundice in dogs will vary depending on the specific underlying cause and the severity of the condition. Regular monitoring and follow-up visits with the veterinarian will be necessary to assess the dog’s progress and make any necessary adjustments to the treatment plan.
By addressing the underlying causes of jaundice and providing appropriate medical care, it is possible to manage the condition and improve the dog’s overall health. Early detection, prompt treatment, and close collaboration with a veterinarian are key factors in achieving positive outcomes for dogs with jaundice.
Jaundice in Newborns vs. Adults
Jaundice, characterized by yellowing of the skin and eyes, can occur in both newborns and adults. However, there are variances in how jaundice presents and the treatment approaches for each group.
Variances in Presentation
In newborns, jaundice is a relatively common occurrence, with about 60% experiencing it within the first couple of days after birth (WebMD). It is often a result of the immature liver’s inability to efficiently process bilirubin, a substance produced when red blood cells break down. As the liver matures, it becomes more efficient in processing bilirubin, and the jaundice typically resolves within a few weeks without intervention.
Newborn jaundice may present as a yellowish tint in the skin and eyes. It usually starts on the face and then progresses downward to the chest, abdomen, and extremities. In most cases, it is a harmless condition that does not require treatment. However, in some instances, if the bilirubin levels become excessively high, treatment with phototherapy may be necessary to help break down the bilirubin (WebMD).
In contrast, jaundice in adults is less common. It can be a symptom of an underlying liver, blood, or gallbladder problem. The causes of jaundice in adults can vary and may include acute viral hepatitis, blocked bile ducts, or gallstones. Symptoms may include yellowing of the skin and eyes, flu-like symptoms, dark urine, and abdominal pain. If experiencing these symptoms, it is important for adults to consult a doctor promptly.
Treatment Approaches
The treatment approaches for jaundice in newborns and adults differ based on the underlying causes and the severity of the condition.
For newborns, jaundice often resolves without medical intervention as the liver matures and becomes more efficient in processing bilirubin. In cases where the bilirubin levels are elevated, phototherapy may be recommended. This treatment involves exposing the baby’s skin to a fluorescent white or blue-spectrum light, which helps break down bilirubin and facilitate its elimination from the body (WebMD).
On the other hand, treatment for jaundice in adults focuses on addressing the underlying condition causing it. This may involve lifestyle changes such as reducing alcohol consumption and managing hepatitis, as jaundice in adults is more commonly associated with liver diseases that can result from factors like excessive alcohol intake (WebMD). Prompt medical evaluation is necessary to determine the cause and appropriate treatment for jaundice in adults.
It’s important to note that phototherapy, effective for treating jaundice in newborns, has not been shown to be effective for treating jaundice in adults (WebMD). Therefore, it is essential for adults experiencing jaundice symptoms to consult a healthcare professional to determine the underlying cause and guide appropriate treatment.
Prevention and management of jaundice in adults involve lifestyle changes, such as reducing alcohol consumption and managing hepatitis, as well as seeking prompt medical attention for symptoms. Regular check-ups and screenings can help detect and manage any conditions that may contribute to jaundice in adults, especially in middle-aged individuals who are more susceptible.
