A majority of the working dog's energy is derived from __________ metabolism.

Question

BlackTom AI · Accepted Answer

The question asks about the primary metabolic energy source for a majority of a working dog's energy needs.
Option 1: Protein. While protein can be used for energy when calories are insufficient, it is not the body’s preferred or primary energy source for endurance work; amino acids are more valuable for tissue repair and other roles rather than supplying most immediate energy.
Option 2: Fiber. Fiber is largely inert in terms of energy for dogs; it is not absorbed efficiently and does not contribute meaningful metabolic energy for work-related activity, so this option is incorrect.
Option 3: Carbohydrate. Carbohydrates provide readily available energy, especially for high-intensity, short-duration efforts. However, in sustained or long-duration activities, fat becomes the dominant energy source, making carbohydrates a secondary contributor in many working-dog scenarios.
Option 4: Fat. Fat yields a high-energy density and becomes the major energy source during prolonged or moderate-to-low intensity work, which aligns with how many working dogs sustain energy over longer periods. Therefore this is the correct choice.
Overall, the statement points to fat as the primary metabolic fuel for most of the energy demands in working dogs during typical endurance work, with proteins and fibers playing lesser or non-energy roles and carbohydrates contributing as a supplementary source during short, intense bouts.
