Frequently Asked Questions


Here are some questions about dogs with hypothyroidism that could help you understand your dog’s condition better.

Can hypothyroidism cause anxiety in dogs?

Like any hormonal changes, hypothyroidism can affect your dog’s behavior. Some veterinarians even suspect that aggression and anxiety are the first symptoms that something is not right with the thyroid function. [3]

So, if you notice your dog being more anxious than it usually is, it’s a normal thing when it comes to hypothyroidism. Once your pet gets used to the medication, its behavior will go back to normal.

How can I help my dog with hypothyroidism?

As soon as you notice the common symptoms of hypothyroidism (shedding, weight gain, low energy, etc.), take your dog to the vet. The professional will do the tests to confirm the condition.

The doctor will prescribe an oral replacement hormone (levothyroxine or L-thyroxine). Your dog will have to take this medication for the rest of its life.

Other than making sure your pet gets the right medications, you should also pay attention to its diet. A balanced, organic dog food free of allergens and high in omega fatty acids will be the best dog food for hypothyroidism.

What happens if hypothyroidism is left untreated in dogs?

If you don’t treat your dog’s hypothyroidism, it will immensely affect its quality of life. The symptoms will get worse, and your pet will also experience other health complications. Some of the health problems may even lead to death. That’s why it’s crucial to treat this condition and ensure your pet has a happy and healthy life.

How quickly does thyroid medication work in dogs?

After only a couple of weeks of taking medications, your pet will become more energetic and active. Of course, some issues like shedding need more time to sort out. The fur of your dog will need around three-four months to recover. Still, if you combine medications with the right dog food high in vitamins and omega fatty acids, the recovery will be faster.

How do you test a dog for hypothyroidism?

You can find out if your dog suffers from hypothyroidism only by taking it to the vet. The professional will run all the necessary tests to check its condition. [4]

These are the tests that vets usually do:

  • Serum biochemistry profile
  • Complete blood count (CBC)
  • Urinalysis
  • Total T4 (thyroxine)
  • Free T4 (free thyroxine)
  • Free T4 (free thyroxine)

What are the symptoms of too much thyroid medication?

Did you notice that your dog has too much appetite, urinates a lot, pants, is nervous, and has an increased heart rate? He/she is experiencing thyrotoxicosis—caused by too high of a dose of thyroid medication.

The vet should check your dog’s blood at least twice a year, preferably 4-6 hours after you give him/her medications. That’s how you’ll be able to monitor the effect that the dose has on the pet.
