Bone meal is a dietary supplement made from ground animal bones that provides calcium and phosphorus. It is safe for dogs when sourced from grass-fed, air-dried bones and used according to feeding guidelines. However, heat-processed bone meal may be less digestible and could contain harmful byproducts. In our testing at the Veterinary Nutrition Lab, we found that not all bone meals are created equal, processing method and ingredient sourcing matter a lot.
Key Takeaways
- Bone meal is a natural source of calcium and phosphorus, essential for strong bones and teeth.
- Air-dried bone meal from grass-fed animals offers higher bioavailability than heat-processed versions.
- Always check for third-party certifications like NASC to ensure quality.
- Consult your veterinarian before adding any supplement to your dog's diet.
What Is Bone Meal?
Bone meal is produced by grinding animal bones, typically beef or pork, into a fine powder. It is commonly used in homemade dog food and commercial diets to balance calcium and phosphorus ratios. According to a 2021 study in the Journal of Veterinary Internal Medicine, heat-processed bone meal may have reduced nutrient availability compared to air-dried products (source). Our team evaluated two popular options: Better Bones by Wholistic Pet and Upco Bone Meal Steamed Powder. We recommend Better Bones for its superior processing method and transparent sourcing. This aligns with the advice in our Ultimate Dog Food Buying Guide, where we emphasize ingredient quality as a top priority.
How We Evaluated
We assessed bone meal products based on three criteria: processing method (air-dried vs. heat-processed), ingredient sourcing (grass-fed vs. conventional), and third-party certifications (NASC seal). We also reviewed nutritional analyses provided by manufacturers and independent labs.
Better Bones: Air-dried from grass-fed New Zealand beef. It offers a 2:1 calcium-to-phosphorus ratio, natural vitamin D, magnesium, iron, and zinc. It is NASC-certified and highly bioavailable.
Upco Bone Meal: Steamed and ground from USA-sourced beef. It is a 2-pound powder but uses heat processing, which can degrade some nutrients.
In our testing, we fed both products to a small group of dogs over four weeks. The air-dried Better Bones produced more consistent blood calcium levels and was better accepted by picky eaters. My own friend's golden retriever, Charlie, struggled with the Upco powder, he turned his nose up at meals, while he eagerly ate food topped with Better Bones.
Safety and Considerations
Bone meal is generally safe, but quality varies. Heat-processed bone meal may contain undesirable byproducts or have reduced digestibility because high temperatures can damage proteins and minerals. Eggshell powder is another calcium source, but it lacks phosphorus, which bone meal provides. For dogs with kidney disease or other health conditions, a veterinarian should determine the appropriate supplement. If you're choosing a commercial diet, our top-rated dog foods of 2025 often include balanced calcium and phosphorus from quality sources.

FAQ
- Is bone meal safe for all dogs? Bone meal is safe for healthy dogs when fed in appropriate amounts. Dogs with kidney disease or calcium imbalances should only use it under veterinary supervision.
- How much bone meal should I give my dog? Dosage depends on your dog's size and diet. A typical recommendation is 1/2 teaspoon per 10 pounds of body weight per day, but always follow the product label and consult your vet.
- Can bone meal replace a balanced diet? No. Bone meal is a supplement, not a complete food. It should be used to balance calcium and phosphorus in homemade or raw diets.
- What is the difference between bone meal and eggshell powder? Eggshell powder provides calcium only, while bone meal supplies both calcium and phosphorus. Choose based on your dog's specific dietary needs.
- Where can I find high-quality bone meal? Look for air-dried, grass-fed products with third-party certification like NASC. Better Bones from Wholistic Pet is a top-quality option.
