^aCalculated using all values from the entire study including discharge weights obtained before implementation of a device wiping procedure to correct the adverse effect of device-related electrostatic charge on the analytical balance

^bCalculated using values beginning April 8, 2011 (equivalent to study Day 10, 11, or 12 depending on the dog) after instituting a device wiping procedure to remove electrostatic charge and thus resulting in accurate and expected discharge weights
