Best Calcium-Rich Foods for Dogs

Ranked by calcium content among foods safe for dogs in the Creature Feast catalog.

Canned Sardines per 100g (with bones): ~380mg calcium Canned sardines with bones are one of the best whole-food calcium sources for dogs. The soft bones are fully digestible and calcium-rich.

Plain Greek Yogurt per 100g: ~110mg calcium Plain Greek yogurt provides highly bioavailable calcium along with probiotics. Choose unsweetened varieties with no artificial sweeteners.

Kale per 100g cooked: ~150mg calcium Kale is one of the best plant-based calcium sources because, unlike spinach, its calcium is not significantly blocked by oxalates.

Broccoli per 100g cooked: ~47mg calcium Broccoli provides well-absorbed calcium with low oxalate content. Serve steamed and chopped for best digestibility.

Eggs 1 large egg (with crushed shell): ~50mg from egg + ~2,000mg from shell Eggshells are almost pure calcium carbonate. Finely ground eggshell powder (half a teaspoon) provides about 1,000mg of calcium for homemade diets.

Bok Choy per 100g cooked: ~105mg calcium Bok choy is an excellent low-oxalate source of calcium for dogs who enjoy leafy greens. Lightly cooked is easiest to digest.

Spinach per 100g cooked: ~136mg calcium (reduced bioavailability) Spinach contains calcium but also oxalates that partially block absorption. It contributes some calcium but should not be the sole source.

Salmon per 100g canned (with bones): ~240mg calcium Canned salmon with bones provides calcium similarly to sardines. The soft, edible bones make it a convenient calcium source.
