Hypothyroidism – What’s That?

24th Oct, 2022

Written by Dr Candice Cooper of Gardens Pet Clinic & Spa

Hypothyroidism is relatively common in dogs, mostly those 4 - 10 years old, medium to large breeds.

This is a condition that’s mostly caused by the destruction of the thyroid gland, leading to an under-active thyroid. Most of the time it’s unknown why this happens, although it’s possible that it may be immune-mediated. The damaged thyroid gland can’t produce enough thyroid hormone that affects all organ systems, so the symptoms are quite variable and non-specific as the bodily functions slow down.

Symptoms that you might see are:

  • Lethargy

  • Weight gain

  • Skin and coat problems

  • Mental dullness

  • Exercise intolerance

  • Heat-seeking behaviour

How is hypothyroidism diagnosed?

A vet will diagnose hypothyroidism based on the clinical examination findings and blood tests, including thyroid hormone testing. There are a few other conditions that can affect thyroid hormones, so it may be necessary to perform ultrasound of the thyroid gland to rule out other causes. Lastly, hypothyroidism may be confirmed if a good response to treatment is seen.

How is hypothyroidism treated?

Life-long daily oral treatment with a synthetic thyroid hormone replacement is usually very effective at treating hypothyroidism.
