Calcium deficiency in Golden Retrievers (detailed introduction) seriously affects their health. Owners must take it seriously. Once a dog is found to be calcium deficient, scientific calcium supplementation should begin. Below are the reasons for calcium deficiency in Golden Retrievers.

　　1. The dog has absorbed calcium from the food, but due to poor calcium metabolism within the dog's body, calcium is excreted and deficiency occurs.

　　2. The dog is otherwise healthy, but calcium deficiency is due to insufficient calcium content in the food.

　　3. The calcium content in the dog's food is sufficient, but due to poor absorption functions such as enteritis or poor appetite, the dog becomes calcium deficient due to poor absorption.
