MHuskies and sled dogs generally require a lot less food than many other breeds of dog. Sled Dogs evolved in harsh and unforgiving northern environments where food was scarce, and as a result their bodies adapted to process food very efficiently. As a result they can extract a relatively high percentage of the available energy and nutrients in their food compared to other breeds. It is often the case that the feeding instructions provided by food manufacturers will suggest feeding more than is necessary for a husky or sled dog, as instructions are not generally breed-specific. This is something to bear in mind when feeding complete dog foods such as kibble or wet food, and is discussed in more detail here
