Medication to Treat Hypothyroidism in Dogs

When a dog does not have enough thyroid hormones, the body is affected. The dog gets skin problems, gains weight and tires easily. This condition, called hypothyroidism, happens when the thyroid glands do not function properly. Hypothyroidism is easily treated.

  1. Diagnosis

    • The vet draws a blood sample from your dog and tests it for thyroid levels. When the test shows low thyroid hormone levels, the condition is called hypothyroidism.

    Treatment

    • Your hypothyroid dog is treated with thyroxin or thyroxine medication. This thyroid hormone replacement is available by prescription.

    Medication

    • Thyroxin is prescribed in a dose suited to your dog. The drug comes in several tablet sizes and under different names depending on the manufacturer.

    Dosage

    • Your dog needs thyroid medication every 12 hours to keep the thyroid hormones at a healthy level. To maintain this level, tablet medication is given twice daily.

    Effects

    • Your dog benefits immediately from the medication. The first week the dog typically has more alertness and energy. Within a few months the dog usually converts fat to muscle and regains his skin and hair health.

    Maintenance

    • Each dog needs medication based on her thyroid level. Tests may be needed every 4 to 6 weeks until the right dosage is reached. Your dog needs medication the rest of her life.
