Though they are not at greater risk of hypothyroidism, Beagles in rare cases have the tendency to develop this disease. Notice your Beagle shedding hair? Check it out because it may not be a skin infection caused by fleas and ticks, the shedding maybe because of hypothyroidism.

The thyroid gland is one of the largest endocrine glands in the body. It is consist of two lobes located at the base of the neck. This gland is known for it produces thyroxine, a hormone that regulates the body’s metabolic rate. This hormone controls how quickly the body burns calories and makes proteins. When thyroxine is not produced sufficiently, hypothyroidism occurs.

Hypothyroidism affects dogs between 4 to 10 years old and is common in middle to large size breeds. It is also common in neutered dogs than in intact animals.

Deficiency of thyroxine or thyroid gland is distinguishable through various symptoms. Excessive shedding and difficulty in growing hair are likely to happen. Excessive black pigment in the skin of their groin is also visible. Other symptoms of hypothyroidism include mental dullness, obesity, low tolerance to cold, slow heart rate, high blood cholesterol and anemia. These symptoms when combined together will be the basis of your veterinarian in diagnosing the presence of hypothyroidism in Beagles.

Hypothyroidism is diagnosed through various tests. These tests are T4 test, T3 test and TSH Stimulation test. The most common is the T4 test wherein blood sample is drawn and then tested. This is to determine the level of T4 thyroid hormone in the bloodstream. T3 test is similar to T4 but is not quite accurate in early case of hypothyroidism. To ensure accuracy, T3 test is oftentimes used together with T4 or TSH Stimulation tests. TSH Stimulation test is used when results of T3 and T4 tests are in doubt.

Hypothyroidism is not a life-threatening disease. This disease is best treated with the use of thyroid hormone or thyroxine. It is available in various brands and comes in tablet form. Dosage of this drug varies depending on the severity of the condition. It is usually based on the dog’s weight, blood samples and to the dog’s response to the drug. Once thyroxine medication is started in dogs, it should be given for the rest of dog’s life.
