How is the Resting Energy Requirement (RER) calculated for dogs?

The Resting Energy Requirement (RER) for dogs is determined using an established formula based on the body weight of the animal. The correct calculation method is to use body weight raised to the power of 0.75, multiplied by a constant such as 70. This method takes into account the allometric scaling of metabolic rates relative to body size, which is why BW^0.75 is used rather than just body weight alone.

This calculation is vital for veterinarians or pet owners in assessing the energy requirements of dogs at rest, ensuring that they receive an appropriate amount of calories based on their size and breed. Utilizing this method helps avoid over- or under-feeding the animal, subsequently impacting their overall health. The alternative formulas presented in the other options do not accurately reflect the metabolic needs as precisely as the correct choice does.
