What causes gallstones in dogs

Gallstones are most commonly a secondary condition. Certain breeds are more prone to developing gallstones than others. These breeds include Poodles, Schnauzers and Shetland Sheepdogs. However, any dog breed can potentially have gallstones.

What causes gallstones is the inability of the gallbladder to function properly. Bile flow is interrupted and it becomes too saturated. That causes the gallstones to form.

Additionally, a build-up of bile can occur due to inflammation, infections, or gastrointestinal diseases.

Gallstones can also form due to taurine deficiency, different environmental conditions, hereditary factors or changes in the lining of gallbladder.

Treatment

If you notice any symptoms of cholelithiasis in your dog, contact your vet. Most of them can be seen on X-rays.

If the gallstones are small enough, your vet will simply dissolve them and follow up with antibiotics. Additionally, he may also prescribe some supplements for deficiencies that caused the gallstones.

Usually, vets will also recommend a high-protein, fat-reduced diet for dogs who have experienced gallbladder complications.

However, if the gallstones are larger enough to cause blockages or perforations, your vet may consider surgery. Very often, the whole gallbladder will be removed. However, that doesn’t have to worry you. Dogs can live a long and healthy life even without their gallbladder. But you will have to follow some specific dietary guidelines.
