The most common cause of significant, clinical hypocalcemia in dogs is puerperal tetany (eclampsia), which typically occurs in nursing mothers. For general, often asymptomatic, low total calcium readings, the most common cause is hypoalbuminemia (low blood protein).

What can cause hypocalcemia in dogs?

There are many causes of low blood calcium besides hypoparathyroidism: low albumin levels, kidney failure, pancreatitis, antifreeze poisoning, exposure to a phosphate enema, low magnesium, nutritional deficiency (especially the infamous "all meat diet"), nursing a litter, and the list continues.

How to treat a dog with low calcium?

Oral calcium supplementation for days to weeks (once stable) Possible vitamin D supplementation, which helps the intestines absorb calcium more effectively. Anti-seizure medication, if the seizures don't respond to supplementation.

What are the three causes of hypocalcemia?

The causes of hypocalcemia can be divided into 3 broad categories: PTH deficiency, high PTH, and other causes. Each of these categories is detailed below. Chronic kidney disease (CKD): CKD leads to impaired phosphate excretion and hydroxylation of 25 hydroxyvitamin D to 1,25-dihydroxy vitamin D.

What happens if a dog doesn't get enough calcium?

If your dog doesn't get enough calcium through their diet they could develop a calcium deficiency. Over time, this deficiency could cause the body to begin leaching calcium from the bones to make up for the deficit, leading to bone pain and weakened muscles.

Can hypocalcemia cause seizures in dogs?

Typically, the hypocalcemia is not associated with clinical signs. Severe clinical signs of hypocalcemia are rarely reported in dogs with protein-losing enteropathy, but seizures, facial twitching, and tremors can occur.

What is the best treatment for hypocalcemia?

Thus, the management of hypocalcemia depends upon the severity of symptoms. In patients with acute symptomatic hypocalcemia, intravenous (IV) calcium gluconate is the preferred therapy, whereas chronic hypocalcemia is treated with oral calcium and vitamin D supplements.

What can elevate calcium in dogs?

Lymphoma (lymphatic cancer) is probably by far the most common cause of elevated calcium in dogs. Parathyroid gland tumor secreting PTH. Kidney failure (altering the calcium and phosphorus balance). It should be noted that kidney failure causes hypercalcemia, and hypercalcemia causes kidney failure.

What does calcium deficiency look like in dogs?

Puerperal hypocalcemia, dog

Panting and restlessness are early clinical signs. Tremors, twitching, muscle spasms, stiffness, and incoordination may also occur. The dog may become disoriented, hypersensitive, and aggressive, and whine, drool, and pace.

What food has the most calcium for dogs?

Chicken and Fish. Chicken is an excellent protein source that contains an adequate amount of calcium. Salmon, trout, mackerel, and sardines also have high calcium content from 170 mg to 370 mg. Because both proteins have sufficient calcium, these meats are often in many types of dog food.

How to correct hypocalcemia in dogs?

Treatment of hypocalcemia is aimed at correcting the underlying disorder. If clinical signs are present, vitamin D, supplementation, calcium supplementation or both are indicated, as for eclampsia. Treatment is also indicated if serum total calcium is <7.5 mg/dL or ionized calcium is <0.8 mmol/L.

What is considered severe hypocalcemia?

Severe hypocalcemia, defined by a serum calcium <1.9 mmol/L (7.6 mg/dL), is often considered an emergency because of a potential risk of life-threatening cardiac arrhythmias or seizures (6, 7, 8, 9, 10, 11).

How do dogs act when they have low blood sugar?

Signs of hypoglycemia (low blood sugar) in dogs include weakness, lethargy, disorientation, trembling, lack of coordination, seizures, and collapse, often appearing suddenly, especially in toy breeds or puppies. Other symptoms can involve behavioral changes, dilated pupils, increased hunger, drooling, vomiting, rapid heart rate, or even coma. Contact your vet immediately if you notice these signs, as hypoglycemia can be serious. 

What is the most common cause of hypocalcemia?

The most common cause of low calcium (hypocalcemia) is hypoparathyroidism, a condition where the parathyroid glands don't produce enough parathyroid hormone (PTH), which regulates calcium levels. Other frequent causes involve Vitamin D deficiency, as it's crucial for calcium absorption, and issues like kidney disease, malnutrition, certain medications, and low magnesium levels. 

Why would calcium drop suddenly?

A low calcium level may result from a problem with the parathyroid glands, as well as from diet, kidney disorders, or certain medications.

What medications can cause hypocalcemia?

Other causes of hypocalcemia include: Certain medications: Bisphosphonates, corticosteroids, rifampin, calcitonin, chloroquine, cinacalcet, Denosumab, Foscarnet and plicamycin can all cause hypocalcemia.

What happens if hypocalcemia is left untreated?

If left untreated, hypocalcemia can increase your risk of serious health problems, including: Abnormal heart rhythms (arrhythmia). Osteoporosis, which causes bones to weaken and increases your risk of fractures.

What foods block calcium absorption?

Your body doesn't absorb calcium well from foods that are high in oxalates (oxalic acid) such as spinach. Other foods with oxalates are rhubarb, beet greens and certain beans. These foods contain other healthy nutrients, but they just shouldn't be counted as sources of calcium.
