Vet’s 2025 Guide to Cholelithiasis in Dogs – Gallstones Diagnosis, Treatment & Prevention 🐶

By Dr. Duncan Houston BVSc

💡 What Is Cholelithiasis?

Cholelithiasis refers to gallstones—solid concretions of cholesterol, bilirubin, or minerals—forming within the gallbladder or bile ducts of dogs. These can be harmless or lead to serious issues like bile duct obstruction or infection.

⚠️ Who’s at Risk?

Middle-aged to older dogs, especially small and female breeds
Dogs with endocrine conditions (hypothyroidism, Cushing’s, diabetes) or lipid disorders
Gallbladder dysmotility and bile infrequent emptying

🔍 What Causes Gallstones?

Bile saturation with cholesterol, bilirubin, or calcium
Chronic inflammation of the gallbladder or bile ducts
Underlying congenital malformations in the bile ducts

🧩 Clinical Signs to Monitor

Vomiting, lethargy, abdominal pain 🇦🇹
Jaundice, fever, anorexia 💛
Occasionally asymptomatic—discovered during routine ultrasound

📋 Diagnostic Approach

Cholelithiasis diagnosis involves:

Physical exam—check abdomen, pain, jaundice
Bloodwork—elevated liver enzymes, bilirubin, GGT, inflammation markers
Ultrasound—stone detection, wall thickening, duct dilation
X-rays/CT—less sensitive than ultrasound, but may detect mineralized stones
Bile or liver biopsy—culture for infection

💊 Treatment Options

1. Medical Management

Ursodeoxycholic acid (15–25 mg/kg q12h) to dissolve stones
S-AME, vitamin E for liver protection and bile flow
Antibiotics for bacterial cholangitis or cholecystitis
IV fluids, low-fat diet, antiemetics as supportive care

2. Surgery (Cholecystectomy / Cholelith Removal)

Recommended if stones obstruct the bile duct, cause infection, or risk rupture. Surgery plus bile duct flushing/cholecystoenterostomy may be required.

Poor surgical outcomes are rare; prognosis is good if managed promptly
Laparoscopic options reduce recovery time

📉 Prognosis

Medical therapy—good in stable cases; requires monitoring ultrasound, and labs
Surgical cases—with prompt treatment, most dogs do well long term
Complicated cases (rupture/infection)—carry a higher risk, but early intervention helps

🛡️ Prevention & Monitoring

Routine abdominal ultrasound in high-risk dogs—e.g., small breeds, older age, endocrine disorders
Manage concurrent disease (Cushing’s, thyroid, lipids)
Low-fat diet, weight management, liver-support supplements
Prompt veterinary care at the first signs of GI upset, jaundice, or abdominal pain

🌟 Real-Life Case Highlight

Case: Bella, an 8-year-old Miniature Schnauzer, displayed elevated liver enzymes on annual labs; ultrasound identified gallstones. She was treated medically with ursodiol, SAMe, antibiotics & diet change. Six-month follow-up showed resolved stones and normalized labs—no surgery needed! 🎉🐾
