Thyroid disorders are common in dogs and can lead to weight gain, lethargy, hair loss, and skin infections. Our Canine Thyroid Panel measures thyroid hormone levels (T3, T4, TSH) to determine if your dog has hypothyroidism or hyperthyroidism. Early detection of thyroid imbalances can help prevent serious health issues. The test is performed through a small blood sample, and results are available within 3 days.
