Science Notes

Eggshell powder is a natural source of calcium, strontium and fluorine which is beneficial for bone metabolism. However, when excess calcium is present in the dogs system, it will inhibit the absorption of phosphorus, so be careful not to over supplement. 

Clinical studies have shown that eggshell powder has a proven positive effect on bone and cartilage and is beneficial in the prevention and treatment of osteoporosis.

If your dog is fed commercial dog food, calcium may already be added, so check the label.
