List of individual weight, body condition score (BCS), diet brand and variety, calculated resting energy requirement (RER) in kilocalories per day (kcal/d), calculated maintenance energy requirements (MER) in kcal/d, percent (%) difference in actual amount of diet fed (kcal/d) to calculated MER, the recommended amount (kcal/d) to feed based on individual’s weight as instructed by diet bag label or website, and the percent (%) difference in actual amount of diet fed (kcal/d) to the recommended amount (kcal/d) based on individual’s weight as instructed by diet bag label or website. Maintenance energy requirements were listed as a range as RER multiplied by a factor of 1.4 to 1.6 to account for a less active and more active lifestyle, respectively. In several diets, recommended daily calorie intake was listed as a range to account for a less active or more active lifestyle. In a total of five subjects (2, 4, 6, 7, and 23) dogs received a range in the amount of food fed daily. For these dogs, their greatest and smallest amount of diet fed daily were averaged. Subject 16 received diet 8k or diet 8l and therefore, both diets were analyzed separately. Quantity of diet fed to subject 19 was not made available. Subject 21 received equal proportions of diet 1a with diet 9m, and therefore, actual calorie intake was calculated by adding kilocalories contributed from both diets.
‡Because subject 21 was fed a combination of diet 1a and diet 9m, daily kilocalories recommended by manufacturer for both diets were averaged to calculate the percent difference between actual amount fed and amount recommended.
