Understanding Hyperparathyroidism in Dogs
Hyperparathyroidism in dogs is a condition characterized by the overactivity of the parathyroid glands, resulting in elevated levels of parathyroid hormone (PTH) and calcium in the blood. There are two main types of hyperparathyroidism: primary and secondary. Additionally, certain breeds are more predisposed to developing this condition.
Types of Hyperparathyroidism
-
Primary Hyperparathyroidism: Primary hyperparathyroidism in dogs is caused by a tumor in one or more of the parathyroid glands, leading to excessive production of PTH. This results in increased blood calcium levels. It is more commonly observed in older dogs and is often caused by a benign tumor. The average age for hyperparathyroidism in dogs is ten years, with a range of 5 to 15 years of age.
-
Secondary Hyperparathyroidism: Secondary hyperparathyroidism in dogs is typically associated with underlying health conditions, such as malnutrition or chronic kidney disease. In these cases, the parathyroid glands produce excess PTH as a compensatory response to low blood calcium levels. This can occur due to a lack of calcium or vitamin D in the diet, impaired absorption, or impaired kidney function (PetMD).
Breeds Predisposed to Hyperparathyroidism
While hyperparathyroidism can affect dogs of any breed, certain breeds have a higher predisposition to the condition. For example, Keeshonds are 50% more likely to develop hyperparathyroidism compared to other breeds. It is important to note that hyperparathyroidism in dogs is not known to have a genetic cause, but the higher occurrence in specific breeds suggests a possible hereditary basis in some cases. Additionally, secondary hyperparathyroidism can develop in association with hereditary kidney disease, although it is not directly inherited (PetMD).
Recognizing the different types of hyperparathyroidism and the breeds more susceptible to this condition is crucial for early detection and improved recovery. If you suspect your dog may be experiencing symptoms of hyperparathyroidism, it’s important to consult with a veterinarian for proper diagnosis and treatment options.
Primary Hyperparathyroidism in Dogs
Primary hyperparathyroidism is an endocrine disorder that affects dogs, primarily caused by a tumor in the parathyroid gland. This tumor leads to an overproduction of parathyroid hormone, resulting in increased blood calcium levels (Wagwalking). It is more commonly observed in older dogs and is typically caused by a benign tumor (Vetspecialists).
Causes and Symptoms
The primary cause of hyperparathyroidism in dogs is the presence of a tumor in the parathyroid gland, which leads to excessive production of parathyroid hormone. This hormone regulates calcium levels in the body, and when its production is disrupted, it results in elevated blood calcium levels (hypercalcemia).
Symptoms of primary hyperparathyroidism in dogs can vary, but they primarily revolve around the increased blood calcium levels. Common symptoms include:
- Increased thirst and urination
- Loss of appetite
- Weight loss
- Weakness and lethargy
- Vomiting
- Abdominal pain
- Kidney stones
- Changes in behavior or personality
It’s important to note that primary hyperparathyroidism can also lead to secondary complications such as renal failure, vitamin D intoxication, and excess calcium in the blood (PetMD). If you notice any of these symptoms in your dog, it’s crucial to seek veterinary attention for a proper diagnosis.
Diagnosis and Testing
Diagnosing primary hyperparathyroidism in dogs involves a comprehensive evaluation and testing process. The veterinarian may consider the following:
- Detailed history: The veterinarian will inquire about the dog’s symptoms, medical history, and any recent changes in behavior.
- Full blood screen: A blood test is performed to measure calcium levels and assess other parameters, such as kidney function.
- Parathyroid hormone measurement: An inappropriately high level of parathyroid hormone in the blood is indicative of hyperparathyroidism. This is often measured to confirm the diagnosis.
- Imaging: X-rays and ultrasound may be used to visualize the parathyroid gland and detect any abnormalities.
- Additional hormone tests: In some cases, additional hormone tests may be conducted to rule out other endocrine disorders.
By conducting these tests and assessments, veterinarians can accurately diagnose primary hyperparathyroidism in dogs and determine the most appropriate treatment plan. Early detection and intervention are crucial for managing this condition effectively.

Treatment Options for Primary Hyperparathyroidism
When it comes to treating hyperparathyroidism in dogs, the primary focus is on addressing the underlying cause and improving the dog’s overall health. The most common treatment for primary hyperparathyroidism in dogs is surgical removal of the affected parathyroid gland, known as parathyroidectomy.
Surgical Procedures
Parathyroidectomy is the preferred treatment option for primary hyperparathyroidism in dogs. During this procedure, the veterinarian surgically removes the abnormal or enlarged parathyroid gland responsible for overproduction of parathyroid hormone. This surgical intervention aims to restore normal calcium and phosphorus levels in the dog’s body.
The surgical removal of the affected parathyroid gland requires a skilled veterinary surgeon and is typically performed under general anesthesia. The procedure involves making an incision in the neck area to access the parathyroid gland. Once located, the abnormal gland is carefully excised while preserving the surrounding healthy tissues.
Postoperative Care
Following parathyroidectomy, the dog will require close monitoring and postoperative care. The veterinary team will provide instructions on wound care, pain management, and any necessary dietary adjustments. Regular follow-up appointments will be scheduled to assess the dog’s recovery and monitor their calcium and phosphorus levels.
It’s important to note that while surgical removal of the affected parathyroid gland is the most common and effective treatment for primary hyperparathyroidism in dogs, alternative treatment methods may include ethanol ablation and ablation with heat. However, these medical treatment options are typically used in the short-to-medium term and are not considered curative.
In cases where secondary hyperparathyroidism is present due to malnutrition or chronic kidney disease, the treatment approach may differ. Secondary hyperparathyroidism can often be managed on an outpatient basis and may involve calcium supplements, low-phosphorus diets, and addressing the underlying condition causing the hormone imbalance.
It’s crucial to consult with a qualified veterinarian to determine the most appropriate treatment plan for your dog’s specific condition. The veterinarian will consider the dog’s overall health, the severity of the hyperparathyroidism, and other individual factors when deciding on the best course of action to ensure the dog’s well-being and long-term health.
Secondary Hyperparathyroidism in Dogs
In addition to primary hyperparathyroidism, dogs can also develop secondary hyperparathyroidism. This form of hyperparathyroidism occurs as a result of underlying conditions or nutritional imbalances. Let’s explore two common causes of secondary hyperparathyroidism in dogs: nutritional causes and renal complications.
Nutritional Causes
Nutritional secondary hyperparathyroidism is primarily caused by malnutrition due to a deficiency of calcium and vitamin D or an excess of phosphorus. This form of hyperparathyroidism is commonly seen in puppies fed an inadequate diet lacking calcium, vitamin D, or with an excessive amount of phosphorus (Wagwalking).
Puppies have high calcium requirements for proper bone and teeth development. Insufficient calcium and vitamin D in their diet can disrupt the balance of calcium and phosphorus in the body, leading to the overproduction of parathyroid hormone (PTH). Excess phosphorus in the diet can further contribute to the imbalance, exacerbating the condition.
To prevent nutritional causes of secondary hyperparathyroidism, it’s crucial to provide puppies with a well-balanced diet that meets their nutritional needs. Consult with a veterinarian to ensure your puppy’s diet includes adequate amounts of calcium, vitamin D, and appropriate phosphorus levels.
Renal Complications
Renal secondary hyperparathyroidism is a complication of chronic kidney disease (CKD). In dogs with CKD, the kidneys are unable to remove phosphorus from the body and do not produce enough calcitriol, the active form of vitamin D. This leads to increased production of parathyroid hormone (PTH) (Wagwalking).
The excessive PTH production in renal secondary hyperparathyroidism not only affects the parathyroid glands but also impacts the kidneys, brain, and bones. The imbalances in calcium, phosphorus, and PTH levels can further contribute to the progression of chronic kidney disease.
Managing renal secondary hyperparathyroidism involves addressing the underlying chronic kidney disease. Treatment focuses on supporting kidney function, managing phosphorus levels, and providing appropriate supplementation of calcitriol or active vitamin D analogs. It’s essential to work closely with a veterinarian to develop a comprehensive treatment plan for dogs with renal secondary hyperparathyroidism.
By understanding the nutritional causes and renal complications associated with secondary hyperparathyroidism, dog owners can be proactive in preventing and managing these conditions. Regular veterinary check-ups, proper nutrition, and appropriate management of underlying health issues are key to promoting the overall well-being of dogs affected by secondary hyperparathyroidism.
Diagnosis and Prognosis
When it comes to diagnosing hyperparathyroidism in dogs, several testing methods are employed to determine the presence of the condition. Additionally, understanding the prognosis and potential for recovery and recurrence is essential for dog owners.
Testing Methods
The diagnosis of hyperparathyroidism in dogs involves a comprehensive approach to assess blood calcium levels, history, full blood screening, and imaging techniques such as x-rays and ultrasound. The primary indicator of hyperparathyroidism is an inappropriately high level of parathyroid hormone in the blood.
During the diagnostic process, it is crucial to rule out other potential causes, including cancer, renal failure, vitamin D intoxication, and excessive calcium in the blood (PetMD). X-ray and ultrasound imaging may be utilized to detect tumors in the parathyroid gland if other diagnostic methods are inconclusive.
Accurate measurement of parathyroid hormone levels is fundamental to confirming the diagnosis of hyperparathyroidism in dogs. These testing methods, combined with a detailed history and comprehensive blood screening, help veterinarians determine the presence of the condition.
Recovery and Recurrence
The prognosis for dogs diagnosed with hyperparathyroidism varies depending on several factors, including the underlying cause, the severity of the condition, and the response to treatment. Prompt diagnosis and appropriate treatment can significantly improve the dog’s quality of life.
Surgical intervention is often the recommended treatment for hyperparathyroidism in dogs. After undergoing surgery to remove the affected parathyroid gland(s), dogs require postoperative care and monitoring. The recovery period can vary, and it is essential to follow the veterinarian’s instructions regarding medication, diet, and activity restrictions.
While most dogs experience a significant improvement in their condition following surgery, there is a potential for recurrence in some cases. Regular follow-up visits and ongoing monitoring of blood calcium levels are crucial to detect any recurrence or complications.
It is important for dog owners to be aware of the signs and symptoms of hyperparathyroidism and seek veterinary care promptly if any concerning symptoms arise. Early diagnosis and appropriate treatment increase the chances of a successful outcome and long-term management of the condition.
Understanding the testing methods used for diagnosis and the potential for recovery and recurrence provides valuable insights for dog owners dealing with hyperparathyroidism in their pets. By working closely with a veterinarian and following their recommendations, dog owners can provide the best possible care and support for their furry companions.
