Cholangiohepatitis in dogs is a rare but serious issue. It causes inflammation in the gallbladder, bile ducts, and liver cells. This can happen due to bacteria or viruses. While cats are more often affected, dogs can get it too.
Signs include poor appetite, fever, losing weight, throwing up1, diarrhea, and turning yellow1.
Catching this early is key for a good outcome. To diagnose it, vets may use blood tests, scans, and liver biopsies2. Treatment involves antibiotics and care based on the dog’s needs. If caught early, most dogs bounce back fully2.
Yet, some dogs may not recover as easily and could lose liver function permanently2. Without control, prolonged inflammation can lead to bad liver damage and failure2. Thus, long-term medicines and regular check-ups are vital for these dogs2. Dogs with severe cases need care from specialists and ongoing tests2.
Supplements like Sam E, milk thistle, and Ursodiol are also important in treating cholangiohepatitis2

Causes of Cholangiohepatitis in Dogs
Cholangiohepatitis in dogs often comes from various reasons. These include bacteria and viruses. Bacteria from the intestine can move to the gallbladder and bile ducts. This might happen if dogs eat raw meat or go through trash, raising their chances of getting sick. Sometimes, viruses can also cause cholangiohepatitis.
Symptoms of Cholangiohepatitis in Dogs
Dogs with cholangiohepatitis may show various symptoms. Signs like losing hunger, fever, and losing weight are common. Also, they might throw up, have diarrhea, and turn yellow, known as jaundice.1 Some might even get a swollen belly due to fluid buildup.1
It’s crucial to understand that these signs are not unique to cholangiohepatitis. This means that similar symptoms could point to different illnesses. So, to make a correct diagnosis, vets need to do a detailed check-up, blood tests, and imaging.1
When dogs don’t feel like eating, it’s often because their liver isn’t working right. The liver is important for breaking down food. Fever is another symptom that suggests inflammation in the liver or bile ducts.1
Dogs may lose weight for many reasons, such as not eating much, not absorbing nutrients well, and the body needing more energy due to inflammation.1 Vomiting and diarrhea are signs too. They show there are problems in the stomach that are linked to liver illness.1
Jaundice makes the skin and eyes yellow. It happens when there’s too much bilirubin, a yellow substance from breaking down red blood cells. If the liver can’t process bilirubin properly, it builds up and causes yellowing.1
Knowing these symptoms helps vets identify cholangiohepatitis in dogs. Catching it early and starting treatment is key to helping dogs feel better.1
| Symptoms | Percentage of Dogs Affected |
|---|---|
| Vomiting | 72.2% |
| Lethargy | 70.4% |
| Inappetence | 64.8% |
| Ultrasonographic abnormalities in the hepatobiliary system | 84% |
| Concurrent biliary disease | 46.2% |
| Biliary tract obstruction | 42.6% |
| Hyperbilirubinemia | 64% |
| Hypercholesterolemia | 56% |

Diagnosis of Cholangiohepatitis in Dogs
Diagnosing cholangiohepatitis in dogs includes various tests to confirm the illness. Blood tests help spot liver inflammation and give clues about the cause. They check for bacteria or viruses, which helps in choosing the right treatment1. Imaging like abdominal ultrasound is key. It lets us see the liver and bile ducts clearly. This way, issues like gallbladder thickening or big bile ducts can be found1.
A liver biopsy might be needed to get a closer look at tissue samples. This can show if neutrophilic cholangitis (NC) or cholangiohepatitis is present1. About half the dogs checked will show signs of other bile diseases at the same time1. Tests for biliary and liver bacteria can also identify common culprits like Escherichia coli and Enterococcus spp.1.
The diagnostic process for cholangiohepatitis in dogs usually needs several tests. Blood tests, imaging, and biopsy are all used together. They help confirm the diagnosis and give a prognosis. These methods are vital for finding the best treatment plan1.
Treatment for Cholangiohepatitis in Dogs
When we talk about treating cholangiohepatitis in dogs, the main focus is on fighting the infection. Vets often start with broad-spectrum antibiotics for a good start2. They might change the antibiotics based on test results, to find the best fit for the dog’s needs. Supporting the dog’s health is very important, especially if they are very sick2. Things like IV fluids keep the dog hydrated, and medicines can help with fever, throwing up, and diarrhea2. Dogs that have issues with their immune system might need extra drugs like corticosteroids to get better2.
Liver supplements could be suggested to help the dog’s liver health. S-adenosylmethionine and milk thistle are favorites because they might protect the liver2. They help by protecting and fixing liver cells. Changing the dog’s diet can also help heal the liver and make the dog feel better2.
Treatment time for cholangiohepatitis in dogs can change. It often lasts six to eight weeks or more, depending on how severe the condition is and the dog’s response to the treatment3. Getting better from cholangiohepatitis can take weeks, especially with serious damage to the liver and bile ducts. Sometimes, scar tissue might prevent a full recovery3.
The outlook for dogs with cholangiohepatitis varies based on a few things. These include how severe the disease is and how far it has progressed. Catching it early and starting treatment quickly helps a lot with getting a good outcome3. It’s a good idea for dogs to get checked every year with blood and urine tests. This could help catch cholangiohepatitis early on3.
Management and Prognosis of Cholangiohepatitis in Dogs
Treating cholangiohepatitis in dogs means a long-term plan and close watch. This helps achieve the best outcome. The prognosis looks good for dogs with infectious cholangiohepatitis, as long as they get the right treatment quickly.
Out of 54 client-owned dogs with cholangitis or cholangiohepatitis, common clinical signs included vomiting (72.2%), lethargy (70.4%), and inappetence (64.8%).1
While many dogs get better with treatment, some face complications. These dogs might need medicine and check-ups for life because of other health issues or immune problems.
Patients that develop a secondary chronic inflammatory liver condition may need lifelong medication and monitoring. Many can be managed for years.2
Cholangiohepatitis can turn into a serious condition that doesn’t stop causing liver inflammation. Without treatment, it leads to liver scarring, cirrhosis, and eventually, the liver stops working.
Chronic, uncontrolled liver inflammation can lead to cirrhosis of the liver and organ failure.2
Regular check-ups are crucial for dogs living with cholangiohepatitis. These visits often involve blood tests and scans to check the liver. They help adjust the dog’s treatment plan when needed.
The median patient survival was 671 days. Dogs that did not undergo cholecystectomy had a 2.1 times greater hazard for death compared to cholecystectomized dogs. Dogs older than 13 years had a 5.0 times greater hazard for death compared to younger dogs.1
For serious cases, dogs may need to stay in the hospital under the care of specialists. Once home, it’s important to have follow-up visits. These check how treatment is working and if any adjustments are needed.
Patients with severe cholangiohepatitis requiring hospitalization for intravenous therapy and support are generally followed by internal medicine specialists during their hospital stay. Follow-up for lab tests, ultrasound, and medication adjustments should be planned after hospital discharge.2

Importance of Early Diagnosis in Cholangiohepatitis
Spotting cholangiohepatitis early is key in treating dogs effectively. Because its signs are hard to pinpoint, finding it early is critical. Doctors use various tests to look for clues. These include special images and lab tests that show liver issues, such as swelling and changes in the gallbladder2.
Doctors often use abdominal ultrasound to check the liver and bile ducts. This helps them spot changes that suggest cholangiohepatitis. Blood tests and checking how the liver works are also vital. They give doctors more information about the liver’s condition2.
Finding the disease early lets doctors start the right treatment quickly. This can stop the disease from getting worse. Dogs that get treated early often recover fully. Research shows that early treatment leads to better health outcomes2.
If the disease is found late, it can make recovery hard and may permanently harm the liver. But, early detection means the treatment can be more aggressive. Tests and maybe a second biopsy can show how bad the liver inflammation is. This helps plan the treatment better, improving the dog’s chance of recovery2.
| Statistical Data | Cholangiohepatitis in Dogs |
|---|---|
| Prevalence in Dogs | Less common than in cats2 |
| Recovery potential | Early diagnosis leads to a higher chance of full recovery with appropriate therapy2 |
| Complicated recovery | Some patients may experience permanent loss of liver function2 |
| Lifelong medication and monitoring | Patients with secondary chronic inflammatory liver conditions may require ongoing treatment and surveillance2 |
| Complications of uncontrolled inflammation | Scar tissue formation, cirrhosis, and organ failure2 |
| Importance of follow-up | Lab tests and occasional biopsies provide a better assessment of inflammation and guide treatment decisions2 |
Finding cholangiohepatitis early is vital for a dog’s health. Veterinarians use advanced tools and exams to spot this disease. This allows for quick treatment decisions. Early detection and treatment can greatly improve a dog’s life quality2.
Canine Cholangitis and Hepatic Dysfunction
Cholangiohepatitis in dogs links to hepatic dysfunction, checked via blood tests and liver exams.1 High levels of enzymes like alanine aminotransferase show liver cell damage. Abnormal bile acid, low albumin, high bilirubin, and cholestasis are other key signs.1
Looking at liver biopsy samples under the microscope is useful. It shows changes in the liver such as bile duct growth and cell necrosis.1 These insights are crucial for understanding liver issues.
Blood tests are vital to learn about liver disease in dogs with cholangiohepatitis.1 These tests watch over liver enzymes, check liver function, and find bile flow and metabolism problems. Examining the liver closely also provides helpful info for treating cholangiohepatitis in dogs.
By using both blood tests and examining the liver, vets gain a full view of the liver problems in dogs with cholangiohepatitis.1 This knowledge is key to guiding treatment, watching how the disease moves, and tweaking treatments as needed.
Hepatic Dysfunction in Dogs with Cholangiohepatitis
| Hepatic Dysfunction Parameters | Prevalence in Cholangiohepatitis Dogs (%)1 |
|---|---|
| Elevated liver enzymes (alanine aminotransferase, glutamate dehydrogenase) | XX.X |
| Abnormal fasting bile acid levels | XX.X |
| Hypoalbuminemia | XX.X |
| Hyperbilirubinemia | XX.X |
| Cholestasis | XX.X |
Ultrasonography and Diagnostic Procedures for Cholangiohepatitis
Ultrasonography is key in diagnosing cholangiohepatitis in dogs. It lets vets see the gallbladder, bile ducts, and liver closely. They can spot signs like gallbladder wall thickening and expanded bile ducts through ultrasonography.
Other tests, like fine-needle aspiration (FNA), also help diagnose and treat cholangiohepatitis. FNA takes a fluid or tissue sample from the gallbladder. It checks for bacteria and inflammation, guiding treatment4.
Along with FNA, gallbladder culture tests the fluid for bacteria. This finds the right antibiotics to fight the infection2. These tests improve diagnosis and treatment plans.
In some dogs, a liver biopsy may be needed for a deeper look at the liver inflammation. It takes liver tissue for study. The biopsy shows liver damage details and helps create a proper treatment plan4.
Using ultrasonography and other tests, vets can accurately diagnose and treat cholangiohepatitis in dogs. These methods offer insights into the disease and assist in picking the right treatments, enhancing dogs’ chances of recovery.
| Diagnostic Procedure | Benefits |
|---|---|
| Ultrasonography | – Visualizes gallbladder and bile duct abnormalities – Assists in diagnosis and evaluation of cholangiohepatitis |
| Fine-Needle Aspiration (FNA) | – Provides samples for microscopic examination – Helps identify bacteria and inflammatory cells |
| Gallbladder Culture | – Identifies and characterizes bacteria present – Guides selection of appropriate antibiotics |
| Liver Biopsy | – Evaluates liver tissue under a microscope – Assesses liver pathology and guides treatment |

Other Considerations in Cholangiohepatitis Diagnosis and Treatment
Besides bacterial or viral infections, other things can cause cholangiohepatitis in dogs. For example, gallbladder mucocele is a condition where too much bile builds up in the gallbladder. This can cause inflammation in the liver and make cholangiohepatitis worse. Sometimes, immune problems also play a role, making diagnosis and treatment more complicated.
To diagnose cholangiohepatitis, vets use different tests. Ultrasound can spot gallbladder mucocele by showing the bile buildup. Liver biopsy and culture tests check for inflammation and infections. These tests help decide the best treatment for each dog.
Treating cholangiohepatitis means dealing with the causes and the liver inflammation. Antibiotics are key for fighting the infection. Dogs might get medicines like penicillins, cephalexin, enrofloxacin, and metronidazole, depending on the case5. Metronidazole is especially good against certain bacteria that affect the liver5.
For ongoing liver problems, corticosteroid therapy is advised5. Drugs like Prednisone help reduce liver inflammation5. If steroids alone don’t work, vets may add azathioprine. For serious liver scarring, colchicine can help stop it from getting worse5.
Some dogs need treatment over a long time. Lactulose helps lower ammonia levels, important for dogs with liver issues5. Ursodeoxycholic acid has been effective in treating chronic liver diseases5.
It’s important to keep an eye on how treatment is going. This might mean blood tests and ultrasounds every few weeks at first3. After things stabilize, yearly check-ups are recommended to make sure dogs stay healthy3.
