Understanding Hyperthyroidism in Dogs
Hyperthyroidism in dogs is a condition characterized by an overactive thyroid gland, which results in excessive production of thyroid hormones. To comprehend this condition fully, it is essential to explore the causes and symptoms associated with hyperthyroidism in dogs.
Causes of Hyperthyroidism
The most common cause of hyperthyroidism in dogs is a cancerous tumor within the thyroid gland, specifically a thyroid carcinoma or thyroid adenocarcinoma, which overproduces thyroid hormones. In rare cases, a benign thyroid mass known as a thyroid adenoma can also lead to hyperthyroidism (PetMD). Additionally, certain dietary factors can contribute to the development of hyperthyroidism in dogs. Consumption of commercial raw meat diets contaminated with thyroid tissue or the ingestion of supplements containing kelp or seaweed can trigger this condition (PetMD). It’s important to note that overmedication with thyroid supplements, typically used to treat hypothyroidism (underactive thyroid), can also result in hyperthyroidism (PetMD).
Symptoms of Hyperthyroidism
Hyperthyroidism in dogs is characterized by various signs and symptoms related to the excess production of thyroid hormones. These symptoms reflect an increased metabolic rate and may include:
- Weight loss despite an increased appetite
- Excitability and restlessness
- Increased thirst and urination
- Vomiting and diarrhea
- Increased heart rate
These clinical signs can be indicative of hyperthyroidism, and if you observe any of these symptoms in your dog, it is recommended to consult with a veterinarian for a thorough evaluation. For a more detailed list of symptoms, refer to our article on hyperthyroidism in dogs symptoms.
Understanding the causes and symptoms of hyperthyroidism in dogs is crucial for timely diagnosis and appropriate treatment. If you suspect your dog may be experiencing hyperthyroidism, it is important to seek veterinary care for proper diagnosis and consideration of suitable treatment options.
Diagnosing Hyperthyroidism in Dogs
When it comes to diagnosing hyperthyroidism in dogs, a veterinary examination and diagnostic tests play a crucial role in confirming the condition.
Veterinary Examination
During a standard veterinary examination, a veterinarian may be able to detect certain symptoms of hyperthyroidism in dogs. These symptoms can include an increased heart rate and the presence of a thyroid mass in the dog’s neck. The veterinarian will carefully palpate the neck area to feel for any abnormalities (VSCOT). However, it’s important to note that a physical examination alone is not sufficient to make a definitive diagnosis.
Diagnostic Tests
To confirm the presence of hyperthyroidism and assess its severity, various diagnostic tests are typically recommended. These tests may include:
-
Comprehensive Bloodwork: Blood samples are collected and analyzed to measure thyroid hormone levels. An elevation in thyroid hormones, such as T4 (thyroxine), is indicative of hyperthyroidism in dogs. Additionally, other parameters, such as liver and kidney function tests, are evaluated to assess overall health (PetMD).
-
Urinalysis: A urinalysis may be performed to evaluate kidney function and assess for any potential complications associated with hyperthyroidism.
-
Imaging Techniques: Ultrasound of the neck and heart, as well as imaging techniques like CT scans or MRI, may be recommended to visualize the thyroid gland and detect any abnormalities. These imaging methods can help determine the size and location of thyroid masses or nodules.
-
Thyroid Scintigraphy: Thyroid scintigraphy is a specialized imaging technique that involves the injection of a radioactive substance. This substance allows for the visualization of the thyroid gland and the assessment of its function and blood supply. Thyroid scintigraphy can provide valuable information to aid in the diagnosis of hyperthyroidism.
It’s important to note that biopsy or fine needle aspiration of a thyroid mass is generally not recommended due to the risk of severe hemorrhage (PetMD). Instead, a combination of the above diagnostic tests is employed to establish a definitive diagnosis of hyperthyroidism in dogs.
By conducting a thorough veterinary examination and utilizing appropriate diagnostic tests, veterinarians can accurately diagnose hyperthyroidism in dogs. This allows for prompt treatment and management to ensure the well-being and overall health of your furry companion.

Treatment Options for Hyperthyroidism
When it comes to managing hyperthyroidism in dogs, there are several treatment options available. The choice of treatment depends on factors such as the size and location of the thyroid tumor, the stage of the cancer, and the overall health of the dog. In this section, we will explore three common treatment options: surgical intervention, radiation therapy, and chemotherapy.
Surgical Intervention
Surgery to remove the thyroid tumor is the most common treatment for hyperthyroidism in dogs, particularly when the tumor is small, freely movable, and has not spread to other parts of the body (VSCOT). This procedure aims to remove the affected thyroid tissue to reduce the excessive production of thyroid hormones.
During surgery, a veterinary surgeon will carefully remove the tumor and, if necessary, a portion of the thyroid gland. The extent of the surgery depends on the size and location of the tumor. It is important to note that in some cases, the tumor may be too large or in a location that makes it difficult to remove surgically. In such instances, alternative treatment options may be considered.
Radiation Therapy
Radiation therapy is another treatment option for hyperthyroidism in dogs. It involves the use of targeted radiation to destroy cancerous thyroid cells. This treatment is typically recommended when the tumor cannot be easily removed surgically or if there is evidence of cancer spread beyond the thyroid gland.
During radiation therapy, the dog receives precise doses of radiation that specifically target the thyroid tissue. This helps to minimize damage to surrounding healthy tissues. The goal of radiation therapy is to destroy the cancer cells and reduce the production of thyroid hormones.
Chemotherapy
In certain cases, chemotherapy may be recommended as a treatment option for hyperthyroidism in dogs. Chemotherapy involves the use of specific drugs that target and kill rapidly dividing cancer cells. It is typically used when the cancer has spread beyond the thyroid gland or if surgery and radiation therapy are not viable treatment options.
Chemotherapy can help to shrink the tumor, slow down its growth, and alleviate the symptoms associated with hyperthyroidism. The specific drugs used and the treatment schedule will depend on the individual dog’s condition and the stage of the cancer. It’s important to note that chemotherapy may be associated with potential side effects, and close monitoring by a veterinarian is essential throughout the treatment process.
The choice of treatment for hyperthyroidism in dogs depends on various factors, including the size and stage of the tumor, the overall health of the dog, and the expertise of the veterinary team. It is important for dog owners to consult with their veterinarian to determine the most appropriate treatment approach for their furry companion.
