Digestive and Liver Health in Collies

Quick answer

Collies are prone to specific digestive and liver conditions that require careful observation. By maintaining a consistent health log and performing regular home exams, you can catch subtle changes early. If your dog shows persistent vomiting, weight loss, or unusual behavior, these are signals to have your veterinarian perform a physical exam and diagnostic blood work to determine the cause.

Pancreatitis

Pancreatitis involves inflammation of the pancreas, an organ essential for digestion. This is a recognised tendency in the breed. Owners often notice this condition when a dog experiences sudden vomiting, abdominal pain, or a hunched posture. You might see your dog stretching frequently or appearing restless because they cannot get comfortable. At home, the most common mistake is waiting to see if the symptoms resolve on their own. If your dog refuses food or seems lethargic, you should have your veterinarian perform a physical exam and blood tests to check pancreatic enzyme levels. This is a recognised tendency rather than a proven one, and how this passes down is not settled.

Exocrine Pancreatic Insufficiency

Exocrine Pancreatic Insufficiency, or EPI, occurs when the pancreas fails to produce the enzymes necessary to digest food. This is a recognised tendency in the breed. It often develops as a result of end-stage chronic pancreatitis in middle-aged to older dogs. The most common sign is a dog that eats ravenously but continues to lose weight. You may also notice the production of large, pale, greasy stools that have a foul odor. Because the dog is not absorbing nutrients, they may appear weak or have a poor coat quality. A veterinarian will typically use a specific blood test to measure the concentration of trypsin-like immunoreactivity to confirm this diagnosis. This is a recognised tendency rather than a proven one, and how this passes down is not settled.

Portosystemic Shunt

A portosystemic shunt is a condition where blood bypasses the liver, preventing the organ from filtering toxins from the bloodstream. Collies tend to have extrahepatic shunts despite being large dogs. This is a recognised tendency in the breed. You might notice your dog acting disoriented, pacing, or pressing their head against walls, especially after eating. Some owners report that their dog seems smaller than expected for their age or has a stunted growth pattern. A veterinarian will likely suggest blood work to check liver function and imaging, such as an ultrasound, to identify the abnormal blood vessel. This is a recognised tendency rather than a proven one, and how this passes down is not settled.
