Dogs and Hypothyroidism

Updated: Jun 4

Hello again from the Compound Lab!

Last time, it was cat week (or at least cat hyperthyroid week). This time, I’ll focus on dogs and their most common thyroid issue: hypothyroidism.

As you might have guessed, HYPOthyroidism is the opposite of HYPERthyroidism. The symptoms of hypothyroidism tend to be the mirror-opposite of hyperthyroidism as well, and can include fatigue, oversleeping, weight gain, and so on. If a vet diagnoses your dog with hypothyroidism, the treatment is straightforward—your dog just needs more thyroid hormone!

Most of the time, levothyroxine is the thyroid hormone of choice. Unfortunately, dogs usually require higher amounts of levothyroxine than what is normally available for people. As an example, the average person may be on a 50mcg daily dose… compared to as much as 1600mcg daily for a dog. Fortunately, compounding can handle these (relatively) massive doses without any trouble.

Like with our other vet meds, we can make levothyroxine in either a flavored liquid or capsule form, so if your doggy is struggling with thyroid issues, we can help!As always, we're available in the lab Monday through Friday, 9am to 5pm. Or you can email me anytime at We’d love to hear from you!

Until next time,
