The relation of calcium, phosphorus and fat levels to minimal calcium and phosphorus requirements”. J Nutr. 70:241-246.</ref> described poor appetite and skeletal malformations in German shepherd puppies fed dietary phosphorus at 0.23% on a dry matter (DM) basis. These effects were largely ameliorated when the dietary content was increased to 0.33% DM. The calcium content was 0.6% DM so the Ca:P ratios were 2.6 and 1.8 respectively, higher than the ideal ratio of around 1:1.

==Dietary Sources==

Phosphorus is more widely distributed than calcium and is found in dairy, meat, vegetable and cereal products. However in cereals and vegetables phosphorus may be combined as phytate, which is less bioavailable. Common sources in manufactured dog and cat foods include bone meal, meat and bone meal, fish meal, and inorganic phosphate salts – usually those of calcium, sodium, potassium or ammonium. Home-made diets that are mostly composed of meats typically have a very abnormal [[Calcium - Nutrition|Ca:P ratio]].
