If you asked me to list some of the most common canine diseases, hypothyroidism would be towards the top of my list. Hypothyroidism is an endocrine disease that is characterized by a deficiency of thyroid hormones, basically an under-active thyroid. Frequently occurring in both dogs and humans, hypothyroidism causes a decreased metabolic rate and can lead to a multitude of systemic complications. Humans with hypothyroidism tend to experience extreme fatigue, unexplained weight gain, changes in skin and hair, and mood fluctuations. With dogs, the symptoms are not much different. However, it may be harder for us humans to detect subtle changes in our dogs since they can be such pros at hiding illness.
Fortunately, hypothyroidism is one disease that can be managed. There is no cure, so treatment is for life. However, the majority of dogs respond very well to treatment and live normal lives. Could your dog be hypothyroid? Learn more about canine hypothyroidism to help you become a better advocate for your dog's health. After all, you are his voice at the vet.

My dog was diagnosed with hypothyroidism after a routine wellness check showed low T4 levels. She had no symptoms until after starting medication: panting, frequent urination. Her levels were rechecked after 3 weeks; vet increased the dosage which resulted in even more panting. I am very skeptical that my dog has this disease because even though my vet says her T4 levels are now where they should be, panting and frequent urination episodes occur daily (usually early and late evening for approx 30 minute duration.) I know the temperature is not causing panting because it’s winter in Canada and i keep the thermostat low. My vet has never mentioned a check of TSH levels, so i am going to enquire now that i’ve read this article.
