List of individual weight, body condition score (BCS), diet brand and variety, calculated resting energy requirement (RER) in kilocalories per day (kcal/day), calculated maintenance energy requirement (MER) in kilocalories per day (kcal/day), and percent (%) difference in actual amount of diet fed (kcal/day) to calculated MER for group 1 diets. Maintenance energy requirements were listed as a range of RER multiplied by a factor of 1.4–1.6 to account for a less active or more active lifestyle, respectively. For dogs being fed multiple diets, % difference in actual vs MER was calculated as an average between the different diets.
1 Calculations for % difference in actual vs MER for subject number 4 were done by averaging the daily kilocalorie recommendations by the manufacturer for both diets.
2 Subject numbers 28 and 29 were alternating diets between diets 1A and 1B with diet 5B. Calculations for % difference in actual vs MER were done by averaging the daily kilocalorie recommendations by the manufacturer for all three diets.
3 Subject number 33 was occasionally fed diet 1B, but calculations were done based on the primary diet being fed.
