Looking for calcium supplements for dogs? As responsible pet owners, we want to ensure that our furry friends receive the proper nutrition they need to thrive. One essential mineral that plays a vital role in a dog’s overall health is calcium. In this comprehensive guide, we will explore the benefits of calcium for dogs, their dietary requirements, signs of calcium deficiency, and the best calcium supplements available.
Calcium is crucial for various aspects of a dog’s well-being. It supports their growth, helps maintain healthy bones and teeth, aids in proper muscle building and function, promotes heart health, and contributes to a healthy nervous system. Just like humans, dogs cannot produce calcium naturally, so they must obtain it from their diet.
How Much Calcium Does a Dog Need?

The recommended daily intake of calcium for a healthy dog is approximately 1.25 grams for every 1,000 calories consumed. However, the specific amount may vary depending on your dog’s daily calorie requirement. It is important to note that dogs in different life stages have varying calcium needs. Growing puppies, lactating mothers, and pregnant dogs typically require higher levels of calcium in their diet. It is crucial to feed them a diet tailored to their specific life stage to ensure they receive the necessary nutrients.
Calcium Requirements for Pregnant and Nursing Dogs

Pregnant and nursing dogs have increased calcium requirements to support the growth and development of their puppies. Insufficient calcium intake during pregnancy can lead to a life-threatening condition called eclampsia or milk fever. Eclampsia commonly occurs when the puppies are between one to four weeks old, during the period when the mother produces the most milk. Providing adequate calcium during this time is essential for the well-being of both the mother and her offspring.
Signs of Low Calcium in Dogs
When a dog has low levels of calcium in their blood, known as hypocalcemia, it can disrupt their normal bodily functions. Smaller breeds and dogs nursing multiple offspring are more susceptible to hypocalcemia than larger breeds with smaller litters. It is important to be aware of the signs and symptoms of low calcium levels in dogs, which may include:
- Muscle tremors
- Seizures
- Stiffness
- Restlessness
- Agitation or unusual behavior
- Excessive drinking and urinating
- Disorientation
These symptoms can also be associated with other diseases, so it is essential to consult a veterinarian who can perform blood tests to accurately assess the calcium levels in your dog’s blood.
Determining the Need for Calcium Supplements
If you suspect that your dog may require additional calcium, it is crucial to consult with your veterinarian before introducing any supplements into their diet. Certain health conditions may necessitate extra calcium supplementation. These conditions include hypoparathyroidism (underactive parathyroid gland), kidney disease and kidney failure, malabsorption, low levels of protein, toxin ingestion, and pancreatitis. A thorough examination and blood tests can help determine if your dog’s calcium levels are indeed low.
The Dangers of Excessive Calcium Intake
While calcium is vital for a dog’s health, it is equally important not to exceed the recommended intake. Giving your dog too much calcium can have adverse health consequences. Excessive oral calcium supplementation can be easily obtained from pet stores or online, but it should always be done under the guidance of a veterinarian. High calcium levels, or hypercalcemia, can lead to severe complications, including irreversible kidney damage. If you suspect your dog has consumed an excessive amount of calcium, it is crucial to seek veterinary care immediately. Some signs of calcium supplement overdose include vomiting, diarrhea, blood in the urine or stool, upset stomach, stomach pain, increased thirst, shaking, dehydration, frequent urination, collapsing, rapid breathing, extreme exhaustion, and muscle weakness.
