If you feed your dog a fresh food diet, you need to supplement with calcium.
You have four choices:
1. Raw meaty bones
The perfect calcium choice if you don't mind blood and sinew clagging up your shagpile!
2. Bone meal
Ground-up bone and marrow. Just make sure it's not garden-grade bone meal which can contain additives, chemical salts or high concentrations of minerals that are toxic to dogs.
3. Calcium carbonate
Sedimentary rock like limestone, chalk and marble, mined and finely ground into powder mainly in China by heating it to a temperature in excess of 900 degrees and then reacting it with hydrochloric acid to form calcium oxide (quicklime) which then becomes calcium hydroxide (slaked lime) before finally being turned into calcium carbonate. It's what most commercial dog and human calcium supplements are made of because it's the cheapest!
4. Ultimate Canine Calcium+
A 100% natural blend of washed, baked and finely ground eggshell calcium together with alfalfa, nettle leaf, dandelion leaf and coconut milk powder to make the calcium better absorbed by the body and all hand-blended in the UK.
