...Jean A. Hall; Jodi C. Vondran; Melissa A. Vanchina; Dennis E. Jewell ABSTRACT Dogs and cats make short-term food choices based on palatability. We hypothesized that, if palatability were masked, long-term food choices would be based on physiological requirements, and circulating metabolite...

... the maximum propulsive GRF produced. We analyzed the effects of experimental alterations in the fore–aft body mass distribution of dogs as they performed rapid accelerations. We measured the changes in trunk kinematics and GRF as dogs accelerated while carrying 10% body mass in saddlebags positioned just...

... compare rapid acceleration with high-speed galloping in dogs to investigate the ways in which body and limb posture and ground forces are altered to produce effective acceleration. Seven dogs were videotaped at 250 Hz as they performed `maximum effort' accelerations,starting in a standing position...

... to demonstrate a relationship between limb mass distribution and energy costs in human subjects. It is not clear whether a similar correlation would hold for quadrupeds, given their very different gaits. The present study addresses this question by measuring the rate of oxygen consumption in domestic dogs...

... much more efficient at converting metabolic energy to mechanical work. The present study analyzes how this decoupling of work and cost might occur. The experimental design employs limb-loaded and back-loaded dogs and allows the energetic cost of locomotion to be partitioned between that used to move...
