Hypothyroidism is the most common hormonal imbalance in dogs, characterized by a deficiency of thyroid hormone. At Union City Veterinary Medical Center, we are dedicated to diagnosing and managing this condition to ensure your pet's health and well-being.

What is Hypothyroidism?

Hypothyroidism occurs when the thyroid gland, located in the neck, produces insufficient levels of thyroid hormones, which are crucial for regulating metabolism.

This condition is most prevalent in medium to large breeds of dogs, typically between the ages of 4 to 10 years. While rare in cats, hypothyroidism can occur transiently following thyroid treatment for hyperthyroidism.

Causes of Hypothyroidism

The primary cause of hypothyroidism in dogs is the immune-mediated destruction of the thyroid gland, accounting for at least 95% of cases. Other causes include:

Immune-Mediated Destruction

The primary cause of hypothyroidism in dogs is the immune-mediated destruction of the thyroid gland.

This accounts for at least 95% of cases.

Natural Atrophy

Natural atrophy of the thyroid gland can lead to hypothyroidism.

This occurs as the gland gradually loses function over time.

Dietary Iodine Deficiency

Insufficient iodine in the diet can cause hypothyroidism.

Iodine is essential for thyroid hormone production.

Neoplasia (Tumors)

Tumors of the thyroid gland can interfere with hormone production.

Early detection and treatment are crucial.

Congenital Issues

Rarely, hypothyroidism can be present from birth.

These cases require specialized care from an early age.

Hypothyroidism affects multiple body systems, leading to a variety of symptoms. According to recent studies, common symptoms in dogs include:

Diagnosis and Treatment

At Union City Veterinary Medical Center, we perform comprehensive blood tests to diagnose hypothyroidism, measuring thyroid hormone levels and assessing overall health. Treatment involves:

Thyroid Hormone Replacement Therapy

Administering synthetic thyroxine (T4) orally, typically twice daily, to restore hormone balance.

Monitoring

Regular blood tests are crucial to ensure the correct dosage and to adjust treatment as needed.

Managing Hypothyroidism

Once treatment begins, we recommend checking T4 levels 2 to 3 weeks after starting medication, with blood drawn 4 to 6 hours post-dose.

Once the appropriate dose is established, T4 levels should be monitored every 6 to 12 months to ensure continued efficacy.
