Gallbladder disease in dogs is not something most owners think about until an older dog suddenly stops eating and starts vomiting. One of the more serious culprits is a gallbladder mucocele, where the gallbladder fills with an abnormal, thick mucus rather than normal, fluid bile.
Small breed dogs are disproportionately affected, and it often occurs alongside hormonal conditions such as hypothyroidism or Cushing's disease, or in dogs with high blood fat levels. Shetland Sheepdogs appear to carry a particular genetic predisposition.
A gallbladder mucocele can obstruct bile flow and, if left unaddressed, cause the gallbladder wall to weaken and rupture, leading to bile leaking into the abdomen, a life threatening emergency. Vomiting or lethargy lasting more than a day, particularly in a small breed senior dog, deserves a prompt vet visit rather than a wait and see approach.
Ultrasound is the primary diagnostic tool, showing a distinctive pattern within the gallbladder often described as looking like a cut kiwi fruit. Bloodwork usually shows elevated liver enzymes. Dogs without symptoms and an early stage mucocele are sometimes managed medically, with medication to thin the bile and treatment of any underlying hormonal condition, monitored closely with repeat ultrasounds. Dogs with clinical symptoms, or any sign of impending rupture, generally need surgical removal of the gallbladder, which, while a significant surgery, has a good long term outlook once the dog recovers from the procedure itself.
Q: Can a gallbladder mucocele be found before symptoms appear? A: Yes, it is sometimes discovered incidentally on an ultrasound performed for an unrelated reason, before the dog shows any signs at all.
Q: Is gallbladder mucocele linked to diet? A: High fat diets and certain medications, including long term steroid use, are known contributing factors in susceptible dogs.
