What is Hypothyroidism?

Hypothyroidism is a thyroid problem that is very common in dogs, and but seldom occurs in cats. Hypothyroidism is due to an underactive thyroid gland and not enough thyroid hormone is produced, thereby slowing everything down.

The common symptoms and signs of hypothyroidism include:
  • Weight gain/obesity
  • Lethargy/low energy levels
  • Dry skin or hair loss
  • Constipation
  • Slow heart rate
  • Anemia
  • Intolerance to cold
  • High blood cholesterol
  • Infertility
  • Seizures


Behavioral changes may also occur and include anxiety and depression, as well as hyperactivity, being unfocused or passive.

What Causes Hypothyroidism?

The exact cause is unknown but it may be caused by an auto-immune response in which the dog’s own immune system kills cells of the thyroid gland. Dogs that usually suffer from recurring skin problems have hypothyroidism.

Certain dog breeds seem to be more predisposed to hypothyroidism than others. This disorder typically affects mid to large size breeds such as Dobermans, Golden Retrievers, Dachshunds, Miniature Schnauzers, Cocker Spaniels and Airedale Terriers.

It develops in dogs between the ages of 4 and 10 years old. Female unspayed dogs tend to be affected more, although it occurs in both males and females. There is no cure for hypothyroidism but with treatment, pets can continue to enjoy good quality of life.

Diagnosing Hypothyroidism

The diagnosis of a hypothyroidism is based on the symptoms, thorough physical examination and review of your pet’s medical history. Certain tests such as a Baseline T4 Test, Baseline T3 Test, or TSH Stimulation Test will be performed if hypothyroidism is suspected. Your vet will choose the test most suited for your dog’s symptoms. Generally, the TSH Stimulation Test will reveal whether your dog has a low T4 or T3 level.

Help for Hypothyroidism

Treatment of hypothyroidism in dogs involves a daily dose of synthetic T4 hormone known as thyroxine (levothyroxine). Thereafter, follow-up blood tests will be taken in about six weeks to ascertain whether there is any improvement. This is life-long therapy but dogs usually go on to enjoy good health for the rest of their lives.
