How it is made?

Most kibble is made using an extrusion process, where ingredients are mixed, cooked under high pressure and heat, formed into bite-sized pieces, and dried. This process extends the shelf life and ensures the food can be stored for extended periods. During production, kibble is often fortified with essential vitamins, minerals, and other nutrients that may be lost during high-heat cooking.

Concerns?

The high heat used in extrusion can reduce the natural nutrient content of some ingredients. While vitamins and minerals are often added back, the food may lose some of its natural flavor and nutritional complexity. Some kibble products may contain artificial flavors, colors, or preservatives, which some pet owners prefer to avoid. Kibble is low in moisture. Many dogs suffer from chronic dehydration. So, it's essential to ensure pets drink plenty of water since a dry diet can contribute to dehydration in some pets.

Additional info?

Kibble is not biologically appropriate and is very hard for dogs to digest, which can lead to all kinds of issues, such as dull skin and coat, itchy skin, allergies, GI upset, and plaque and tartar buildup. Also, it is a MYTH that kibble cleans teeth. The carbohydrates in the food can adhere to the teeth and gums, leading to poor oral health.
