Common Small Dog Breeds Prone to Liver Disease

Small dog breeds that are notably prone to liver disease include the Yorkshire Terrier, Maltese, Shih Tzu, Chihuahua, Cairn Terrier, West Highland White Terrier, and Havanese. These breeds have a higher risk of developing various inherited and acquired liver disorders due to genetic predisposition and breed-specific vulnerabilities.

1. Yorkshire Terrier

  • Highly susceptible to congenital portosystemic shunts, a condition with abnormal blood vessels bypassing the liver.
  • Prone to microvascular dysplasia (MVD), affecting liver function.

2. Maltese

  • Predisposition to portosystemic shunts and glycogen storage disease Type 1A, which can be severe.
  • Early detection and management are crucial.

3. Shih Tzu

  • Higher rates of liver failure and other hepatic disorders.
  • Conditions like shunts and inflammatory liver diseases are common.

4. Chihuahua

  • Genetic predisposition to liver diseases such as portosystemic shunts, MVD, and chronic hepatitis.
  • Regular veterinary screenings are necessary.

5. Cairn Terrier

  • At risk for chronic hepatitis and congenital vascular anomalies.
  • Microvascular dysplasia may manifest later in life.

6. West Highland White Terrier

  • Develop portosystemic shunts and MVD, often with genetic links.
  • Recommend early liver screening.

7. Havanese

  • At risk for MVD and portosystemic anomalies.
  • Disease is often detected in routine bloodwork in young dogs.

Other Notable Breeds

  • Bichon Frise, Dandie Dinmont Terrier, and Bedlington Terrier are also prone, particularly for copper storage disease.
  • Australian Terrier, Skye Terrier, and Toy Poodle have lower risk but remain susceptible.

Why Are Small Dogs More Prone?

  • Genetics: Inherited mutations affecting liver development and metabolism.
  • Vascular Anomalies: Portosystemic shunts and MVD predominantly affect small breeds.
  • Storage Diseases: Metabolic diseases commonly impact toy and miniature breeds.

Key Insights and Expert Recommendations

  • Regular Wellness Checks: Vital for early detection, particularly in at-risk breeds' first two years.
  • Genetic Testing: Breeder-supported genetic screening can identify some conditions.
  • Liver-Friendly Diet: Diets designed for less hepatic strain may slow disease progression.

Key Things to Remember

Breeds like the Yorkshire Terrier, Maltese, Shih Tzu, Chihuahua, Cairn Terrier, West Highland White Terrier, and Havanese face significant liver disease risks. Early, proactive veterinary care and screening are essential to enhance lifespan and wellbeing.
