Twenty-six commercial dog foods were analyzed. They represented the 4 main types of products intended to support the growth and maintenance of normal dogs, and the special dietary products intended primarily for use in dogs with chronic renal failure. None of the products contained extremes of protein, fat, or carbohydrate that could cause nutritional problems. Several products contained concentrations of calcium that might be too high if fed ad libitum to pups. The renal diets tended to be marginal in sodium and potassium contents, especially for use during renal or cardiac disease. Estimates of available energy were used as the basis for recommending amounts of the 4 main types of dog food to be fed daily to dogs of various body weights. These deviated widely from comparable recommendations in the 1972 NRC Nutrient Requirements of Dogs but agreed almost exactly with those in the 1974 Gaines Baisc Guide to Canine Nutrition.
对26种市售狗粮进行了分析。它们代表了旨在支持正常犬生长和维持健康的4种主要产品类型，以及主要用于慢性肾衰竭犬的特殊饮食产品。这些产品均未含有可能导致营养问题的过高蛋白质、脂肪或碳水化合物。有几种产品的钙含量，如果随意喂给幼犬，可能会过高。肾脏疾病专用狗粮的钠和钾含量往往偏低，尤其是在肾脏或心脏疾病期间使用时。可用能量的估计值被用作推荐每日给不同体重犬喂食4种主要类型狗粮量的依据。这些数值与1972年美国国家研究委员会《犬类营养需求》中的类似建议有很大偏差，但几乎与1974年《盖恩斯犬类营养基础指南》中的建议完全一致。
