Hypothyroid Problems in Pets

If your pet has a problem with excessive shedding or seems too tired to play catch, it may be a sign of a thyroid problem. Dr. Ian explains what causes this disease and how it is treated.

Hypothyroidism usually caused by one of two diseases: lymphocytic thyroiditis or idiopathic thyroid gland atrophy. The first disease is the most common cause of hypothyroidism and is thought to be an immune-mediated disease. This means that the immune system decides that the thyroid is abnormal or foreign and attacks it. It is not known why the immune system does this.

Hypothyroidism is treatable but not curable. It is treated with oral administration of a thyroid replacement hormone. This drug must be given for the rest of the dog’s life.

Signs of hypothyroid problems in your pet:

• Weight gain
• Lethargy
• Cold intolerance
• Dry coat with excessive shedding
