Buyer's Guide: How To Choose The Best Calcium Supplements for Dogs

Before purchasing calcium supplementation products, always consult your veterinarian. They can offer guidance and approve or disapprove of potential supplements.

However, there are some common-sense considerations to keep in mind when shopping for calcium supplements:

1. Consider supplements that are supported by clinical, third-party-verified studies

Don’t be swayed by extravagant claims. Only consider actual results and studies from reputable sources. Unfortunately, the FDA does not monitor supplements and their claims, so you should exercise caution.

2. Company names

Stick with reputable, well-known brands when choosing supplements. It is not worth attempting to save a few dollars by choosing lesser-known or untested brands.

3. Vet-approved

If your veterinarian recommends a particular product, follow their advice.

Your veterinarian is a trusted source of information and can recommend the best supplement for your pet’s specific needs. By adhering to their advice, you can ensure your pet’s health and well-being.

4. Nation of origin

Ideally, you should choose a product made in the United States.

Choosing products made in the United States can provide several benefits, including supporting local businesses and ensuring that the product meets regulatory standards.

Additionally, products made in the United States are typically subject to more stringent quality control measures, ensuring that you receive a high-quality product.

When selecting a product, be sure to check the label to determine its country of origin. If possible, choose products made in the United States to support domestic businesses and ensure the highest quality standards.

5. Lot figures

Lot numbers are necessary to ensure that all product batches undergo quality testing.

Lot numbers provide a unique identifier for each batch of product, allowing manufacturers to track and monitor the quality of their products. This information is crucial for ensuring that the products meet regulatory standards and are safe for consumers to use.

By checking the lot number on a product, you can verify that it has undergone proper quality testing and is safe to use.

6. Only pet products

Only use pet products for your dog. Never give them human supplements, which may contain substances that are harmful to your dog.

While some human supplements may seem similar to pet supplements, they may contain ingredients that can be toxic or harmful to dogs. Additionally, human supplements are often formulated for human needs and may not provide the necessary nutrients that dogs require.

To ensure your dog’s safety and health, only use products specifically formulated for pets. Always consult with your veterinarian for advice on which supplements are best for your dog’s individual needs.

7. Calcium alone or in a mixture

In some cases, pure calcium may be sufficient, while in others, a combination of supplements may be necessary. It is essential to work closely with your veterinarian when administering calcium supplements.

Calcium requirements can vary depending on factors such as age, breed, and overall health. Your veterinarian can help determine the appropriate dosage and type of supplement for your pet’s specific needs.

8. Vitamin D3 addition

Some calcium supplements include Vitamin D3 to facilitate absorption. While not always necessary, it is important to consult with your veterinarian before administering any supplement.

Vitamin D3 can aid in the absorption of calcium, making it an additive in some calcium supplements. However, not all pets require additional vitamin D3, and it is essential to consult with your veterinarian to determine if it is necessary for your pet.

9. Source

Calcium derived from seaweed is a more eco-friendly option that often contains other essential nutrients. Additionally, it is more easily absorbed by the body.

Beef bone-derived products may pose a risk of transmitting mad cow disease, so it may be preferable to use pork-derived products for calcium supplementation.

While it is unclear whether canines can contract these prion diseases, it is important to exercise caution.

FAQs

1. What is the best calcium to give dogs?

Yogurt is a delicious and easily available source of calcium for dogs. It is also rich in probiotics, which support digestive health. Depending on your dog’s age and health, low-fat curd can also be a good option.

2. Can I give my dog calcium supplements?

Calcium supplements may be necessary for homemade diets or in pregnant or nursing dogs, but should only be used under veterinary supervision. Too much calcium can cause health problems, so it is important to follow your vet’s guidance.

3. Can I give calcium to my dog everyday?

According to the National Research Council (NRC), healthy adult dogs generally require 50 mg of calcium per kilogram of body weight per day. For example, a 5 kg dog needs 250 mg of calcium daily, while a 50 kg dog needs 1250 mg per day.

4. Are eggs a good source of calcium for dogs?

Egg shells are an excellent source of calcium for dogs, as they contain amino acids and collagen that promote joint health and mobility. The membrane between the egg shell and egg white is particularly beneficial.

5. What gives dogs high calcium?

Hypercalcemia, or high calcium levels in dogs, can be caused by diseases affecting the small parathyroid glands in the neck. A benign tumor on a parathyroid gland can cause too much hormone to be produced, leading to high calcium levels.

6. What are the symptoms of low calcium in dogs?

Dogs with low calcium levels may experience muscle twitching, weakness, loss of appetite, and listlessness. In severe cases, seizures or convulsions may occur.

7. Can dogs have calcium and vitamin D tablets?

Vets may prescribe vitamin D supplements for dogs at risk of deficiency. Calcium supplements should only be given under veterinary supervision, as too much calcium can be harmful.
