As a pet owner, you know that your dog’s health is paramount. One aspect of that health that may not be immediately apparent is the level of calcium in your dog’s blood. High calcium levels, also known as hypercalcemia, can have serious implications on your pet’s wellbeing. In this article, we delve deep into the causes of high calcium levels in dogs and how to manage it.

Key Takeaways
- High calcium levels in dogs, also known as hypercalcemia, can be caused by various factors, such as cancer, kidney disease, and ingestion of certain types of plants or products.
- Recognizing the signs of hypercalcemia early can lead to effective treatment and management.
- Regular vet check-ups and blood tests are crucial in monitoring your dog’s calcium levels.
Understanding Hypercalcemia in Dogs
Hypercalcemia is a condition characterized by above-normal levels of calcium in the blood. While calcium plays a crucial role in your dog’s body, aiding in bone development and nerve function, too much of it can lead to serious problems, such as kidney stones and heart issues[^1^].
In dogs, the normal range for blood calcium is between 8.9 and 11.4 milligrams per deciliter (mg/dL). When these levels exceed 12 mg/dL, hypercalcemia is diagnosed.
Causes of High Calcium Levels
High calcium levels in dogs can be caused by numerous factors. Some of the most common include:
- Cancer: Certain types of cancer, such as lymphoma and anal gland carcinoma, can cause hypercalcemia in dogs[^2^].
- Kidney Disease: Chronic kidney disease can lead to an imbalance in calcium and phosphorus, resulting in hypercalcemia.
- Vitamin D Toxicity: Vitamin D helps regulate calcium levels in the body. However, excessive amounts can lead to high calcium levels. This could occur from ingesting certain types of plants or rat poison that contain high levels of vitamin D.
- Hypoadrenocorticism: Also known as Addison’s disease, this condition can cause an increase in blood calcium levels.
- Primary Hyperparathyroidism: This is a rare condition where the parathyroid glands produce too much parathyroid hormone, leading to elevated calcium levels.
The table below provides a quick summary:
| Cause | Explanation |
|---|---|
| Cancer | Certain types of cancer can elevate calcium levels |
| Kidney Disease | Can lead to an imbalance in calcium and phosphorus |
| Vitamin D Toxicity | Excessive amounts can lead to high calcium levels |
| Hypoadrenocorticism | Can cause an increase in blood calcium levels |
| Primary Hyperparathyroidism | Rarity where the parathyroid glands produce too much parathyroid hormone |
Symptoms and Diagnosis
The symptoms of hypercalcemia in dogs can be subtle and often mimic other conditions. They include excessive thirst and urination, loss of appetite, vomiting, constipation, and lethargy.
If you notice any of these symptoms or suspect that your dog has high calcium levels, it is important to seek veterinary care immediately. Diagnosis typically involves a blood test to measure calcium levels and other potential tests to pinpoint the underlying cause.

Treatment and Management
Treatment for high calcium levels in dogs depends on the underlying cause. For instance, if cancer is the cause, chemotherapy or surgery may be required. If the cause is kidney disease, a special diet and medications may be necessary.
In some cases, hospitalization and intravenous fluids may be required to lower calcium levels quickly.
