Dog food types
Is kibble dehydrated or baked?
Last updated 23 September 2026 · How we write and check this
Short answer
Standard kibble is neither purely dehydrated nor oven baked, it is extruded: cooked briefly under high heat and pressure through a machine, then dried afterward to remove remaining moisture. A separate category of baked dog food does exist and uses a slower oven process that produces a denser, less puffed piece.
How extrusion differs from baking
Extrusion cooks dough for under a minute at high pressure and temperature, which is efficient at scale and gives kibble its familiar puffed texture. Baked food is cooked more slowly, often 20 to 40 minutes at lower temperatures, similar to baking a biscuit, resulting in a denser, chewier piece.
Does the method change nutrition much
Both methods gelatinize starches enough for a dog to digest them and both require added vitamins afterward since heat degrades some of them during cooking. Neither method is clearly superior nutritionally, they mainly produce different textures and costs.
Reading the bag for clues
Brands that use baking rather than extrusion usually market it explicitly as oven baked since it is a selling point and more expensive to produce at scale, so if a bag does not say so, assume it is standard extruded kibble.
Key takeaways
- Standard kibble is extruded, cooked briefly under heat and pressure, then dried.
- Oven baked dog food is a separate, slower, more expensive process producing a denser piece.
- Neither method is clearly more nutritious, the difference is mainly texture and cost.
