Hypothyroidism is a condition that affects the thyroid gland and causes it to produce less of the hormone thyroxine. This hormone regulates many critical bodily functions, such as metabolism and heart rate.

What are the symptoms of hypothyroidism in dogs? 

If your dog has been feeling a little more sluggish than usual, losing hair, or gaining weight for no reason, they may be suffering from hypothyroidism.

If left untreated, hypothyroidism can cause serious health complications in dogs.

This article will discuss what hypothyroidism is, the symptoms to look for, and how it’s treated in dogs.

What is the thyroid gland?

The thyroid gland is a small, butterfly-shaped gland located in the neck. It produces hormones that regulate many essential body functions, such as metabolism, heart rate, breathing, and body temperature.

Hypothyroidism is an underactive thyroid, causing a slow down in metabolism.

Hyperthyroidism is when the thyroid is overactive, elevating the body’s metabolism.

What dog breeds are prone to hypothyroidism?

While any dog can develop hypothyroidism, certain breeds are more prone to the condition. Mid- to large-sized dogs are most commonly affected, with toy and miniature breeds at the lowest risk.

The most common age for a dog diagnosed with hypothyroidism is 4-10 years old.

Dogs at the highest risk of developing hypothyroidism are:

  • Golden Retrievers
  • Dachshunds
  • Cocker Spaniels
  • Labrador Retrievers
  • Doberman Pinscher
  • Boxers
  • Irish Setter
  • Miniature Schnauzer

What are the common symptoms of hypothyroidism in dogs?

The most common symptom of hypothyroidism in dogs is weight gain. If you notice your dog gaining weight without an increase in appetite, you should have your dog examined by your veterinarian.

  • Lethargy
  • Hair loss
  • Dry skin and coat
  • Cold intolerance
  • Exercise intolerance
  • Recurrent infections
  • Infertility
  • Slow heart rate

How is hypothyroidism diagnosed?

Your vet will complete a total thyroxin (TT4) level blood screening to diagnose hypothyroidism. This test will measure the primary thyroid hormone to determine if your dog has low thyroxin levels.

Any sign of low thyroxin levels, plus characteristics in behavior or appearance, will warrant further detailed testing.

The next step is a thyroid panel or a free (T4 by ED) — free thyroxin by equilibrium dialysis.

Since your dog can have low levels of TT4 with normal levels of free T4 by ED, this is a more definitive test to diagnose hypothyroidism.

The brand names of levothyroxine are Thyro-Tabs® Canine and Synthroid®.

To avoid these serious health problems, it’s essential to have your dog checked by a vet and start treatment if they are diagnosed with hypothyroidism.
