Liver shunt in dogs - what are the symptoms? - briefly
Liver shunts in dogs occur when blood bypasses the liver, leading to a buildup of toxins. Common symptoms include lethargy, poor growth, and neurological issues such as seizures or disorientation.
Liver shunt in dogs - what are the symptoms? - in detail
Liver shunts, also known as portosystemic shunts (PSS), are a serious condition in dogs where abnormal blood vessels allow blood to bypass the liver, preventing it from filtering out toxins and waste products effectively. Recognizing the symptoms of liver shunts is crucial for early diagnosis and intervention.
Symptoms of liver shunts in dogs can vary depending on the severity and type of the shunt. The most common signs include:
-
Neurological Symptoms: These are often the first noticeable symptoms due to the buildup of toxins in the brain. They may include:
- Lethargy or listlessness
- Confusion or disorientation
- Aimless pacing or circling
- Head pressing (dogs may press their head against a wall)
- Seizures or tremors
- Blindness or changes in vision
-
Gastrointestinal Symptoms: The liver plays a significant role in digestion, and any disruption can lead to gastrointestinal issues. These may include:
- Loss of appetite
- Vomiting
- Diarrhea
- Weight loss
-
Urinary Symptoms: Toxins that the liver is unable to filter out can affect the kidneys and urinary system, leading to:
- Increased thirst
- Frequent urination
- Urine with a strong odor
-
Behavioral Changes: Dogs with liver shunts may exhibit unusual behavior due to the buildup of toxins in the brain. This can include:
- Aggression or irritability
- Depression or lethargy
- Changes in sleep patterns
-
Physical Symptoms: Some dogs may show physical signs such as:
- Small body size or failure to grow (in puppies)
- Slow heart rate
- Low body temperature
-
Vascular Issues: In some cases, dogs with liver shunts may develop vascular issues due to the abnormal blood flow, leading to symptoms such as:
- Enlarged liver or spleen
- Abdominal distension or fluid buildup
If your dog exhibits any of these symptoms, it is essential to consult a veterinarian promptly. Early diagnosis and intervention are crucial for managing liver shunts effectively. Treatment options may include medical management with drugs that help reduce the amount of toxins in the bloodstream, or surgical procedures to close the abnormal vessels and reroute the blood flow through the liver.
