Thyroid Problems in Dogs

Hypoactive Thyroid :

Hypothyroidism, or underactive thyroid, is a common occurrence in dogs, caused by a low production of thyroid hormones secreted in the blood by the thyroid gland.

Symptoms of hypothyroid in dogs:

• Weight gain/obesity


• Lethargy/low energy levels


• Dry skin or hair loss


• Constipation


• Slow heart rate


• Anemia


• Intolerance to cold


• Increased blood cholesterol levels


• Infertility


• Seizures

Certain dog breeds appear to be more likely to develop hypothyroidism than others, particularly the larger breeds such as Dobermans, Golden Retrievers, and Dachshunds. Affected dogs may be smaller than their siblings, have large heads and short legs, and usually hold on to their puppy hair coats. Hyperthyroidism can be hereditary, so it would be unwise to breed dogs with this condition.

Hypothyroidism is rare in cats, however, their symptoms are similar those seen in dogs. Some cases appear in cats who have undergone treatment for hyperthyroidism.
