What is hypercalcemia in dogs?
Total calcium includes ionized calcium, complexed calcium, and protein-bound calcium. In most laboratories, hypercalcemia is documented when serum total calcium concentration is > 12.0 mg/dL in dogs. The exact value when hypercalcemia exists must be determined for each laboratory.
Can natural treatments help dogs with hypercalcaemia?
Natural dogs health offers a much safer, more effective way both to treat and to prevent canine hypercalcaemia and canine cancer. Firstly, your dog is put on a quality, natural diet. In itself this can effect a total resolution. But by adding homeopathic treatment, you are boosting your dog’s immune system, allowing him to treat himself.
What to do if your dog has high calcium levels?
A test to measure albumin (a blood protein) should also be done at the same time to check that the pet is not dehydrated. If the repeated value for total calcium is still high, then doing an ionized calcium test is recommended since it is the definitive test for measuring calcium levels.
Can prednisone help with hypercalcemia in dogs?

What is the most common cause of high calcium levels?
The most common cause of high calcium blood level is excess PTH released by the parathyroid glands. This excess occurs due to: An enlargement of one or more of the parathyroid glands.
How is parathyroid treated in dogs?
The most commonly performed treatment for hyperparathyroidism is surgical removal of the affected gland (parathyroidectomy). Ideally the affected gland is identified before surgery but, in some cases, this is not possible and the correct gland can only be identified during the procedure.
What should I feed my dog with hyperparathyroidism?
Your veterinarian will prescribe a low phosphorous diet. With severely high phosphorus levels, your dog will be treated with chemicals that bind to excess blood phosphorous. Calcitrol will also be given in order to increase calcium levels.
Can dehydration cause high calcium in dogs?
Typically, free ionized calcium is elevated in dogs with hypercalcemia associated with malignancy and primary hyperparathyroidism, but not in dogs with renal failure, hypoadrenocorticism, or dehydration.
How long can a dog live with primary hyperparathyroidism?
The development of renal failure was correlated with total calcium concentration but did not correlate with any other factor, including the calcium phosphate product. Thirteen treated dogs were known to be alive at the time of writing, which was six months to 3.5 years after parathyroidectomy.
What foods should I avoid if I have hypercalcemia?
Your provider may ask you to limit foods with a lot of calcium, or not to eat them at all for a while. Eat fewer dairy foods (such as cheese, milk, yogurt, ice cream) or don't eat them at all. If your provider says you can eat dairy foods, don't eat those that have extra calcium added.

There are, however, many other medical situations/conditions where calcium levels can increase enough to result in serious and possibly life-threatening consequences — involving the other complex, physiological functions: blood clotting, nerve impulse conduction, and heart muscle contractions.
Is hypercalcemia common in dogs?
Hypercalcemia is not common in any species but is encountered more often in dogs than in cats. As is so often the case in veterinary medicine, clinical signs of hypercalcemia can be very vague and nonspecific: Increased thirst and urination. Decreased appetite. Lethargy and depression.
Can hypercalcemia be fatal?
Left untreated, hypercalcemia can be fatal. The first thing that should be done is a recheck blood test for calcium to verify that the level is, indeed, elevated and that the diagnosis of hypercalcemia is correct. Note that number one on Dr. Peterson’s list of likely causes was lab error.
What are the factors that cause humoral hypercalcemia?
Factors that may be produced by tumors and result in humoral hypercalcemia of malignancy include PTH, PTH-related protein (PTHrP), transforming growth factor, 1,25-dihydroxyvitamin D, prostaglandin E 2, osteoclast-activating factor, and other cytokines (interleukin-1, interleukin-2, and γ-interferon).
Why is my cat's calcium level high?
In cats, idiopathic hypercalcemia appears to be the most frequent cause of a high total calcium concentration, followed by renal failure and malignancy. Ionized hypercalcemia in conjunction with chronic renal failure is more common in cats than dogs.
How to treat normocalcemia?
If normocalcemia has not been restored after a dietary feeding trial of 6–8 wk, treatment with glucocorticosteroids or bisphosphonates should be considered. Prednisone is given orally at 5 mg/cat/day for 1 mo before reevaluation. If the serum ionized calcium concentration is normal, this dose is continued for several months. If the ionized calcium value is still increased, the dosage is gradually increased to 10–20 mg/cat/day as needed to restore normocalcemia. Alternatively, treatment with the bisphosphonate alendronate can be instituted, starting at 10 mg orally once weekly; the dosage can be increased to 20–30 mg per week, as needed. It is extremely important to administer alendronate after a 12-hour fast, because food significantly reduces drug absorption; the fast should also be continued for at least 2 hr after alendronate administration. Erosive esophagitis is a known adverse effect of oral bisphosphonates in human patients. Although the risk of development of esophagitis in cats is unknown, the owner can give 5–6 mL of water to the cat with a dosing syringe immediately after administration of the alendronate; a small amount of butter applied to the cat’s lips may increase licking and salivation and promote the transit of the pill to the stomach. The longterm safety and efficacy of oral bisphosphonates in cats are currently unknown, but alendronate appears to be relatively safe for use in cats.
What is the most common tumor in dogs?
The most common tumor associated with hypercalcemia in dogs, lymphoma is also one of the tumors associated with hypercalcemia in cats. The pathogenesis of the hypercalcemia may involve two general mechanisms. One is local elaboration of an osteolytic factor that induces resorption of bone and mobilization of calcium when the bone marrow is infiltrated by tumor cells. The other, probably more important, is humoral hypercalcemia in which neoplastic cells produce a humoral factor that acts at a distance from the tumor. As evidence for secretion of a humoral substance by tumor cells, increased bone resorption, phosphaturia, and urinary excretion of cyclic adenosine monophosphate (cAMP) have been documented in dogs with lymphoma . Serum concentrations of both PTH and 1,25-dihydroxyvitamin D are generally low in these dogs, but PTHrP has been detected in dogs with lymphoma (see Characteristic Laboratory Abnormalities Associated with Common Causes of Hypercalcemia ).
How does hypercalcemia affect the body?
The development of clinical signs from hypercalcemia depends on the magnitude of the calcium increase, how quickly it develops, and its du ration. Serum total calcium concentrations of ≤15 mg/dL may not be associated with systemic signs, but serum concentrations of >18 mg/dL are often associated with severe, life-threatening signs. Polydipsia and polyuria are the most common signs of hypercalcemia and result from an impaired ability to concentrate urine and a direct stimulation of the thirst center. Anorexia, vomiting, and constipation can also develop as a result of decreased excitability of GI smooth muscle. Decreased neuromuscular excitability may lead to signs of generalized weakness, depression, muscle twitching, and seizures.
What does decreased excitability mean in dogs?
Decreased neuromuscular excitability may lead to signs of generalized weakness, depression, muscle twitching, and seizures. There are many potential causes of hypercalcemia (see Causes of Hypercalcemia in Dogs and Cats ).
Can hypercalcemia cause kidney damage in dogs?
Hypercalcemia can be toxic to all body tissues, but major deleterious effects occur in the kidneys, nervous system, and cardiovascular system. The development of clinical signs from hypercalcemia depends on the magnitude of the calcium increase, how quickly it develops, and its duration.
How to treat hypercalcemia in dogs?
The treatment for hypercalcemia depends on what information the physical, blood work, and diagnostic test revealed. If your veterinarian determines that your pet is dehydrated, it will be necessary to rehydrate him by administering fluids by intravenous or subcutaneously (under the skin). If the blood concentration is very high in the bloodstream, your veterinarian team may recommend hospitalization in order to start drug treatment. If your pet is diagnosed with cancer, surgery and chemotherapy may necessary.
What does hypercalcemia mean in dogs?
Hypercalcemia in dogs means that the level of calcium in the canine’s bloodstream is abnormally high. High calcium levels can be a secondary symptom associated with serious diseases such as Addison’s disease, kidney failure, parathyroid gland tumor and cancer. Protect yourself and your pet. Compare top pet insurance plans.
What is Hypercalcemia?
Calcium is essential for blood clotting, cardiovascular, neuromuscular, immune and endocrine function. Bones need calcium to keep them healthy and strong. If the bones lose too much calcium because it is going instead into the bloodstream, they will become weak. The bones of the canine will be more susceptible to bone fractures.
What hormones are responsible for calcium in dogs?
The bones of the canine will be more susceptible to bone fractures. Calcium levels are controlled and monitored by the parathyroid glands. The parathyroid hormones and vitamin D interact to release calcium from the bones, stomach, and kidneys, which is then transferred to the canine’s bloodstream. High levels of calcium in your canine’s bloodstream ...

However other possibilities exist; therefore a thorough diagnostic investigation is recommended. Working with both your family veterinarian and a board-certified veterinary internal medicine ...
What is the test for calcium in the blood?
The initial documentation of high blood calcium is relatively straightforward. After performing a complete physical examination, a veterinarian will order a non-invasive blood test called a serum biochemical profile. This test measures a form of calcium in the blood called total calcium (tCa).
What is the name of the gland that regulates calcium and phosphorus levels?
Hyperparathyroidism: The parathyroid glands are located in the neck, and are responsible for helping regulate calcium and phosphorus balance in the body. When these glands secrete too much parathyroid hormone, blood calcium levels often rise and blood phosphorus levels tend to decrease. Hypoadrenocorticism: Also known as Addison’s disease, ...
What is ionized calcium?
Measurement of ionized blood calcium: Ionized calcium (iCa) is different from total calcium in that the former is considered the active form of calcium in the body. Ionized calcium is involved in various metabolic processes. Total and ionized blood calcium levels can change differently depending on the underlying disease process.
Why do dogs get dehydrated?
Dehydration: When dogs don’t drink enough water, they can become dehydrated quickly, a finding that can be associated with mild elevations of total blood calcium . Idioapathic: In some patients with hypercalcemia we never figure out what causes the abnormality.
What to do if your dog has hypercalcemia?
Further testing will be needed to assess the health of the kidneys, adrenal glands, and parathyroid glands. If there is a history of vitamin D supplementation, testing for levels of vitamin D would also be appropriate. Your veterinarian may also want to examine your pet for signs of underlying cancer.
What happens if your dog has high calcium levels?
Pets with abnormally high calcium levels may show signs of weakness, listlessness, increased drinking and urination, and loss of appetite. In some pets, prolonged hypercalcemia may contribute to formation of bladder or kidney stones.
How are levels of calcium controlled in the healthy animal?
Calcium levels are controlled by a pair of parathyroid glands . The two tiny glands are embedded in the thyroid gland, which sits just below the larynx or "voice box" overlying the windpipe. The parathyroid glands are responsible for monitoring the calcium level in the blood. When calcium levels are too low, the glands release a hormone called parathyroid hormone (PTH), which acts to return calcium levels to normal.
Why is having high calcium bad for my pet?
Pets with abnormally high calcium levels may show signs of weakness, listlessness, increased drinking and urination, and loss of appetite. In some pets, prolonged hypercalcemia may contribute to formation of bladder or kidney stones.
How are calcium levels measured?
Two forms of calcium are found in blood, called total calcium and ionized calcium (also called free calcium ).
What further testing is required if my pet has high total calcium on a routine blood test?
Before repeating total calcium, the pet should be fasted for 12 hours, but must have access to water. A test to measure albumin (a blood protein) should also be done at the same time to check that the pet is not dehydrated. If the repeated value for total calcium is still high, then doing an ionized calcium test is recommended since it is the definitive test for measuring calcium levels. In some situations, your veterinarian may advise that your pet have the ionized calcium test after finding a high total calcium.
What does it mean when a pet has low parathyroid hormone?
If a pet has hypercalcemia but has low levels of parathyroid hormone, then it suggests there has been a breakdown in the normal mechanism that controls calcium levels. This is worrisome because it may mean that there is underlying cancer. The pet should be thoroughly examined, and additional diagnostic tests may be recommended, including radiography, ultrasound, cytology, or biopsy.
How to treat hypercalcemia in animals?
Complete excision of isolated neoplasms will abolish hypercalcemia, and in animals with disseminated metastases, multicentric neoplasia, or nonresectable primary malignancy, tumor burden and hypercalcemia may be decreased by appropriate chemotherapy, radiation therapy, and immunotherapy. Supportive therapy is often necessary to decrease serum calcium concentration to less toxic levels. Unfortunately, there is no single treatment protocol consistently effective for all causes of hypercalcemia, and thus regimens must be tailored for each patient.
What is the most common underlying diagnosis for hypercalcemia in dogs?
In hypercalcemic dogs, neoplasia is the most common underlying diagnosis, followed by hypoadrenocorticism, primary hyperparathyroidism, and chronic renal failure. Approximately 70% of hypercalcemic dogs are also azotemic, with azotemia uncommon only in dogs with hyperparathyroidism.
What causes hypercalcemia in dogs?
Diseases result in hypercalcemia by causing increased bone resorption of calcium, decreased renal excretion of calcium, increased GI absorption of calcium, increased serum binding of calcium to proteins/complexes, or a combination of these processes. The causes of hypercalcemia noted in referral hospitals may not reflect the same frequency of diagnosis encountered in primary care facilities. Observations from a primary care biochemistry laboratory indicate that renal failure is most commonly associated with hypercalcemia in the dog.
What is the serum calcium level in dogs?
When a serum sample is submitted to the laboratory, typically the total serum calcium concentration is what is reported. Total calcium includes ionized calcium, complexed calcium, and protein-bound calcium. In most laboratories, hypercalcemia is documented when serum total calcium concentration is > 12.0 mg/dL in dogs. The exact value when hypercalcemia exists must be determined for each laboratory. Serum total calcium and serum ionized calcium values are lower in cats than in dogs. In our laboratory, hypercalcemia in dogs is defined when the total serum calcium is greater than 11.6 mg/dL and the ionized calcium concentration is greater than 6.0 mg/dL.
Why does ionized calcium increase?
Patients with moderate to severe metabolic acidosis undergo increases in their ionized calcium fraction due to shifting of calcium from protein-bound stores of calcium. For these reasons, measurement of serum ionized calcium concentration is recommended in all patients with renal failure or hypercalcemia.
How to reduce calcium in dogs?
Guided by ultrasound, ethanol is injected into the parathyroid mass. Both total and ionized calcium concentrations return to normal within 24 hours in most dogs. Transient hypocalcemia may develop, and may require treatment.
What are nonpathologic conditions associated with hypercalcemia?
Nonpathologic conditions associated with hypercalcemia include non-fasting (minimal increase), physiologic growth of young animals, laboratory error, and spurious as a result of lipemia or detergent contamination of the sample/tube.
