Vet Tech Rounds: Hyperthyroidism And Hypothyroidism in Pets

The difference between hyperthyroidism and hypothyroidism in pets can be very confusing. But, don’t worry, we’re here to help. The terms for describing both conditions are very similar and can cause a mix-up between the two. Both affect the thyroid but work in opposite ways. One way that I learned to remember the meaning for each condition in veterinary school, was that HYPO always refers to something being slow while HYPER always means that something is fast or overactive. For example, exactly how we would describe a kid after eating candy: hyperactive!


The thyroid hormone also known as T3 controls the body’s metabolic rate. In other words, it will decide how hard and how fast each cell will have to work to perform its function. The actual thyroid glands do not produce T3, they produce another form that is called T4. The different tissues in the body will absorb T4 and they turn it into T3.

Hyperthyroidism is a common condition in cats and does not affect dogs as often.

Hyperthyroidism is caused by growth from the thyroid gland that causes an overproduction of T4. As mentioned before, hyper means that things are moving at a faster pace so hyperthyroidism will cause your pet to lose a lot of weight, excessive thirst, restlessness, excessive eating, and urinating.

It is important to note that hyperthyroidism is a common condition in cats and does not affect dogs as often. Some of the symptoms associated with hyperthyroidism are:

  • Weight loss
  • Vomiting
  • Diarrhea
  • Heart problems
  • Excessive drinking/urination
  • Increase in appetite

As mentioned, hyperthyroidism is not found commonly in dogs but can be caused by hypothyroidism medication. This type of medication contains a synthetic form of thyroxine and can lead to hyperthyroidism.

Hyperthyroidism can be diagnosed with blood testing that will measure the levels of the thyroid hormones. Other blood samples may be taken for general testing in case of a secondary issue. It can be controlled with the use of the right medication. However, if it’s a tumor causing the problem, surgery may be required, and chemotherapy can also be an option.

Hypothyroidism is more common in dogs than cats.

Hypothyroidism affects mainly canine companions. The thyroid glands fail to produce enough T4 and T3 hormones. This is generally caused by one of two things: lymphocytic thyroiditis or idiopathic thyroid gland atrophy. Lymphocytic thyroiditis is an autoimmune condition, and this means that the immune system attacks the thyroid, because it thinks it is abnormal. Unfortunately, we do not know why this occurs, but evidence shows that it is a heritable condition, therefore, the cause is for genetic reasons.

Symptoms of hypothyroidism are basically opposites to the symptoms of hyperthyroidism. Hypo is referring to everything slowing down, so some of the typical symptoms associated with it are:

  • Lethargy
  • Weight gain and obesity
  • Increased shedding
  • Hair thinning and hair loss
  • Reproductive problems
  • Dull appearance
  • Thickening of the skin

Hypothyroidism is tested by doing a total thyroxin level (TT4). Like the test for hyperthyroidism, this will measure the thyroid hormone level in the blood. A definitive diagnosis is made by doing a free T4 by equilibrium dialysis. This will measure the levels of thyroxin and if the results show low levels then it is most likely hypothyroidism.

Neither of the above conditions has cures but both can be controlled using prescribed medication. The drug given is a thyroid replacement hormone and must be administered for the rest of your pet’s life. The dose will depend on your pet’s weight and thyroid levels. Sometimes the dose may need to be adjusted over time.

Hypothyroidism is a slow-developing condition and can often be misdiagnosed.
