Understanding Mitral Valve Disease in Dogs: New Advances and Holistic Support

Mitral Valve Disease (MVD) is the most common heart disease in adult dogs, particularly affecting small breeds and older dogs. Recent research is providing new hope, with advances in diagnosis and treatment making it easier to manage this challenging condition.

One exciting breakthrough involves microRNAs (miRNAs)—tiny fragments of RNA that regulate gene expression. A new study has found that miRNAs can help detect myxomatous mitral valve disease (MMVD) early and may even distinguish between different stages of the disease:

• Preclinical stages (M1 and B2): When there are no outward symptoms but structural changes in the heart are present.

• Clinical stages (C and D): When symptoms like coughing, difficulty breathing, or exercise intolerance occur.

Why Early Detection Matters
“Catching this disease early can significantly improve the quality and longevity of life for affected dogs,” explains Dr. Robert Coultous, chief scientific officer and cofounder of MI:RNA, the company leading this study. By identifying MMVD before symptoms appear, veterinarians can intervene earlier, potentially slowing the disease’s progression and preventing further damage to the heart.

Holistic Options for Supporting Your Pet's Heart Health

Dr. Andrew Jones, author of Veterinary Secrets, suggests several natural remedies to support dogs with heart disease. These alternatives can complement conventional treatments and may improve your dog’s overall well-being.

1. Dandelion

   • Why it helps: This natural diuretic reduces fluid buildup in the lungs and abdomen—a common symptom of heart disease. Unlike conventional diuretics like furosemide (Lasix), dandelion contains potassium, which helps prevent deficiencies caused by frequent urination.

   • Dosage: 1 ml of tincture per 20 lbs of body weight daily, or as needed.

2. Hawthorn

   • Why it helps: Hawthorn strengthens the heart’s ability to pump blood and dilates blood vessels, making it easier for the heart to work.

   • Dosage: ½ ml of tincture per 20 lbs twice daily.

3. Coenzyme Q10 (CoQ10)

   • Why it helps: CoQ10 is an antioxidant that protects the heart muscle from damage and supports its function.

   • Dosage: 5 mg per 10 lbs of body weight daily.

4. Omega-3 Fatty Acids (from Krill Oil)

   • Why it helps: Omega-3s improve heart function, reduce irregular heartbeats, lower blood pressure, and decrease the risk of blood clots.

   • Dosage: 500 mg of krill oil per 25 lbs of body weight daily
