Is calcium good for dogs? Read on to find out more!
Is Calcium Good for Dogs?
Calcium is a mineral that supports a dog’s development, bone and dental health, proper muscle development and function, cardiovascular health, and nervous system health. Dogs cannot naturally generate this mineral; therefore, they must consume food sources of it.
Calcium has various forms. Calcium powder for dogs is one of the most common because it is easy to incorporate it into one’s food.

Our Favorite Brand
Everyone is aware that calcium is crucial for a healthy dog diet; however, there are several calcium facts you may need to learn; for instance, calcium is a metal. Or that calcium is a component of skeletal structure?
Because Revival Animal Health Breeder's Edge Oral Cal Plus - Fast Absorbing Oral Calcium Supplement for Dogs & Cats has these qualities, it is our favorite brand.
The Right Calcium Dosage for Dogs
0.002 ounces (50 milligrams) of calcium per kilogram of body weight is the recommended calcium intake for adult, healthy dogs. As a result, a 10-pound (4.5 kilograms) dog will need about 0.0079 ounces (225 milligrams) of calcium daily.
The quantity of calcium that a dog needs depends on its age, breed, gender, and lifestyle. For instance, to maintain their strength and encourage healthy bone growth in the puppies, pregnant and nursing dogs need more calcium than usual.
Additionally, having insufficient calcium while expecting can cause eclampsia, a potentially fatal condition. But more on this later. According to the Association of American Feed Control Officials (AAFCO), 0.044 ounces (1.25 grams) of calcium per 1,000 calories should be in your dog’s food.
Signs of Low Calcium in Dogs
The medical issue known as hypocalcemia affects your dog if the calcium levels in its blood are below normal. Essential body processes include the development of bones and teeth, blood clotting, milk generation, muscular contraction, heart pumping, eyesight, and the metabolism of hormones and enzymes, and all depend on calcium.
Depending on the underlying reason and seriousness of the issue, symptoms change. However, a few of the more widespread signs include the following:
- Trembling and twitching of muscles
- Stiff or awkward posture
- Panting
- Face bumping into things
- Vomiting
- Having no appetite
- Fever and weakness
When the total calcium level is moderate, symptoms might not appear until it drops far below normal 0.009 oz/dL (6.7 mg/dL).
Once your dog has a calcium deficiency, a veterinarian should do a full physical examination, blood chemical profile, complete blood count, and a urinalysis test. The other tests’ findings will help identify the cause of hypercalcemia.
It is also possible to diagnose underlying diseases such as renal disease, bladder stones, or cancer using radiographs and ultrasound imaging.
Treatment for your dog will most likely need to be hospitalized for fluid therapy if there is a diagnosis of hypercalcemia, according to your veterinarian.
The Dangers of Too Much Calcium Intake
Four parathyroid glands in the neck secrete the hormone the body requires to control calcium and phosphorus.
When vitamin D and parathyroid hormone interact, calcium is released from the bones, stomach, and kidneys and deposited into the bloodstream. Hypercalcemia can happen when malignant cells produce hormones that interfere with calcium control.
The presence of an excessively high level of calcium in the blood is what causes hypercalcemia. Some of the dangers of too much calcium intake include the following:
- Parathyroid gland dysfunction or overactivity (hyperparathyroidism)
- Tumors or cancer
- Illnesses that damage the bones
- Chronic kidney failure
- Adrenal glands that aren’t working properly
- Food poisoning from vitamin D (supplements included)
- Aluminum toxicity

FAQs on Canine Calcium
Is Calcium Chloride Safe for Dogs?
Digoxin or calcitriol-treated animals and those with heart or renal problems should utilize calcium supplements with caution. Although there is no formal examination, using it during pregnancy or on nursing mothers is usually thought to be safe when done so under your veterinarian’s supervision and at the correct dose.
What Can I Feed My Dog as a Supplement Alternative?
We are taught from an early age that calcium is necessary to develop into big, powerful adults. Your dogs are no exception. Try including these natural sources in their diet:
Bones
Your dogs can get a lot of calcium from bones. You will be fine enticing your dog to eat this calcium-rich treat if you use bones as a source of calcium. They satisfy their craving for something to chew on and may even support the development of healthy teeth.
Green Leafy Vegetables
Any dark leafy green, except for bulky meals like broccoli, is suitable for your dog’s diet. Who would have believed that feeding a salad to your dog could be advantageous? Try to include leafy greens like kale and spinach in any meals you prepare for them.
Fish
Because it also adds so many other helpful elements to the mix, fish is one of the greatest calcium sources for your dog. Additionally, feeding your dog fish rather than leafy vegetables is frequently easier.
Dairy Products
Dairy products can be beneficial for dogs, but there is a big catch to this addition to our list. Products such as milk, cheese, and yogurt, can upset the stomachs of many lactose-intolerant dogs.
If you wish to provide your dog the calcium levels it needs by using dairy products, test it out in tiny batches or consult your veterinarian first.
How Can You Make Homemade Calcium for Dogs?
Dogs enjoy eggs, which we frequently feed them. But given the abundance of eggs in the kitchen, it makes sense to wonder if dogs can consume eggshells as they are a good source of calcium.
One of the most essential nutrients for dogs is calcium. It is crucial for blood coagulation, muscle mobility, and bone health. Eggshells are inexpensive and simple to add more calcium to your dog’s diet.
To ensure your dog gets enough calcium, top their homemade food with this easy-to-make powdered supplement. All you would need is some eggshells and something to pound it into powder form.
