Understanding Canine Cholestasis: Symptoms and Signs of Bile Duct Obstruction in Dogs

Pet owners are often vigilant about their furry friends' health, and recognizing the symptoms of potential illnesses is crucial. One such condition that can affect dogs is cholestasis, a condition where bile flow from the liver is obstructed. This article will delve into the symptoms and signs of bile duct obstruction in dogs, commonly referred to as cholestasis.

Jaundice: A Telltale Sign

One of the most noticeable symptoms of cholestasis in dogs is jaundice. Jaundice is the yellowing of the skin, whites of the eyes, and mucous membranes due to elevated levels of bilirubin in the blood. Bilirubin is a waste product that is normally processed by the liver and excreted in bile. When bile flow is obstructed, bilirubin accumulates in the body, leading to jaundice. If you notice a yellowish tint to your dog's skin or eyes, it's essential to consult a veterinarian immediately.

Abdominal Pain and Swelling

Dogs with cholestasis may experience abdominal pain and swelling. The obstruction of bile flow can cause the liver to become inflamed and enlarged, leading to discomfort. Your dog may exhibit signs of pain, such as whining, restlessness, or a reluctance to move. Swelling in the abdomen can also be a sign of fluid accumulation or an enlarged liver, which should prompt immediate veterinary attention.

Changes in Appetite and Weight Loss

A decrease in appetite is a common symptom of cholestasis in dogs. The obstruction of bile flow can interfere with the digestion and absorption of fats, leading to a loss of appetite. As a result, dogs may experience weight loss. If your dog suddenly starts refusing to eat or loses weight rapidly, it's important to seek veterinary care to determine the underlying cause.

Diarrhea or Vomiting

Gastrointestinal symptoms such as diarrhea or vomiting can also be indicative of cholestasis. The obstruction of bile flow can disrupt the normal digestion process, leading to gastrointestinal upset. If your dog has persistent diarrhea or is vomiting, it's essential to consult a veterinarian to rule out cholestasis and other potential health issues.

Dark Urine and Pale Stools

Another sign of cholestasis in dogs is dark-colored urine and pale stools. Bile contains a pigment called biliverdin, which gives feces their typical brown color. When bile flow is obstructed, the pigment is not excreted, leading to pale stools. Additionally, bilirubin may be excreted in the urine, causing it to appear dark. These changes in urine and stool color can be early indicators of cholestasis.
