The German Shepherd (German: Deutscher Schäferhund, German pronunciation: ) is a breed of medium to large-sized working dog that originated in Germany. In the English language, the breed's officially recognized name is German Shepherd Dog (GSD). Several dietary factors play a crucial role in maintaining skeletal health and are described as follows. Appropriate calcium levels are vital in developing a strong skeletal system and aid in preventing orthopaedic diseases like Canine Hip Dysplasia. Furthermore, the ratio of calcium and phosphorus must be balanced and at a recommended ratio of 1.2:1 to ensure proper bone development and structure. Imbalances in calcium and phosphorus levels can result in various skeletal complications. Excess phosphorus can produce lesions in bones whereas excessive calcium can lead to hypocalcaemia and result in excess bone deposition, interfering with normal bone development. In extreme circumstances of insufficient calcium intake, bone resorption can occur due to the body withdrawing calcium deposits from the skeletal frame as a last resort to fulfill dietary needs.
