Hypothyroidism In Dogs: Causes, Symptoms, And Treatments

Here’s what you should know about hypothyroidism in dogs.

What Causes Of Hypothyroidism In Dogs?

This disorder can be found in any dog though it’s less common in smaller breeds and more common in several specific breeds that have a predisposition for developing the condition.

It can appear due to this predisposition in the following breeds:

  • Airedale Terriers
  • Boxers
  • Cocker Spaniels
  • Dachshunds
  • Doberman Pinschers
  • Golden and Labrador Retrievers
  • Great Danes
  • Greyhounds
  • Irish Setters
  • Miniature Schnauzers
  • Old English Sheepdogs
  • Poodles

German Shepherd Dogs and mixed breeds usually become victims of hypothyroidism.  It may develop in your dog around the ages of four to ten years old. Remember! the breed is not the only factor facing hypothyroidism. Spayed females seem to develop the condition more than un-spayed females, though the reason for that is unclear.

The condition may also develop due to the following causes:

  • Immune disease (autoimmune thyroiditis)
  • Atrophy of thyroid tissue
  • Lack of exercise
  • Tumor on the thyroid
  • Exposure to medications such as steroids
  • Adrenal disorder

What Are the Symptoms Of Hypothyroidism In Dogs

Hypothyroidism in dogs affects metabolism because it blocks a crucial function in the body. It’s necessary for all organs and the entire body to function. Because of this, the symptoms can be quite variable.

Here are a few of the most common symptoms:

  • Depression or lethargy
  • Changes in behavior including aggression or anxiety
  • Head tilting
  • Hair loss and thin coat
  • Frequent naps and loss of interest in exercise
  • Dry, discolored, or infected skin
  • Weight gain, obesity, and muscle loss
  • Cold intolerance
  • Ear and toenail infections
  • Slow heart rate
  • Seizures
  • High cholesterol
  • Anemia

How To Treat For Hypothyroidism In Dogs

We can treat the Hypothyroidism in dogs with daily oral drugs. Yet, the treatment is perhaps continuous. Even though the condition is not necessarily life-threatening, it can significantly decrease the quality of life for a dog who has it.

Hypothyroidism is treatable in dogs with daily oral drugs. However, this treatment is ongoing for the rest of life once the condition is diagnosed. Vets usually prescribe a synthetic hormone called levothyroxine or L-thyroxine, and it doesn’t cost much. Moreover, your vet may prescribe thyroid glandular and the cofactors — tyrosine and iodine — to try and bring thyroid hormone production back to normal. Furthermore, vets will strictly monitor your dog’s blood for signs of progress.
