Although humans don’t feed other animals as well as they feed themselves, human society has gone as far as developing food designed just for being consumed by dogs and other canines. Dogs’ dietary needs are largely different from what humans eat. For example, dog teeth are entirely sharp and pointy, indicating that dogs evolved primarily as carnivores. Further, dogs have relatively short digestive tracts; plants are not processed anywhere as near as effective as meat is in these species-wide specialized gastrointestinal systems. Dry, crunchy, roughly round bits of healthy dog food known as kibble were initially invented some 160 years ago in England, which doubled as a way of cleaning dogs’ teeth. Are dog foods that different from one another, anyway?

Dry dog food. This type of healthy dog food – again, it is referred to as kibble – is the most popular type of manufactured food designed intently for consumption by canines. One of the benefits of using dry dog food is that it stays good for days or weeks at a time after leaving it in dog bowls, something that wet dog food simply can’t do. Kibble also lasts longer on shelves than wet dog food does, even if that wet dog food is stored in a refrigerator or other cool place above freezing temperature. People who regularly enter their dogs into agility, jumping, or skill competitions typically travel with dry dog food instead of its wet counterpart because kibble is infinitely easier to travel with.
