Allometric equations (Y = aBWb) for maintenance energy requirements of adult dogs based on the log-log regression of metabolisable energy (kcal.day−1) and body weight (kg).

The format of the allometric equations is as follows: Y = aBWb; where Y: energy requirement; a: allometric coefficient; BW: bodyweight; b: allometric exponent.1Back-transformed using the inverse of log-base10.2Size subjectively scored as toy, small, medium, large, and giant, using the criteria of Hawthorne et al 2004 [18] and Hosgood & Scholl 1998 [85].3For most groups, activity level was classed as low (3 h/day) based upon the criteria of Butterwick and Hawthorne (1998) [7]; however, activity levels were classed as ‘resting’ when measurements were taken either when lying still in lateral recumbency or when cage rested. DLW: doubly-labelled water; F: female; FE: feeding experiment; I: intact; IC: indirect calorimetry; M: male; Mix: study contains a mix of sexes or different neuter status; N: number of treatment groups; Neu: neutered; SE: standard error.Allometric equations (Y = aBWb) for maintenance energy requirements of adult dogs based on the log-log regression of metabolisable energy (kcal.day−1) and body weight (kg).
