Unlike conventional kibble that undergoes high-heat extrusion, dehydrated food uses gentler processing that retains more of the original nutrients and natural enzymes. Before serving, you rehydrate it with warm water, which also increases moisture intake, benefiting pets prone to urinary issues or those that do not drink enough. Dehydrated diets often contain fewer artificial preservatives because low moisture naturally inhibits bacterial growth. They tend to cost more per serving than kibble but less than fresh or frozen raw diets. Check that any dehydrated food carries a complete-and-balanced AAFCO statement if you intend to use it as a primary diet rather than a topper.
