Do dogs need carbohydrates in their diet?

Dogs have no AAFCO minimum carbohydrate requirement, meaning they can technically meet energy needs from protein and fat alone. However, carbohydrates in commercial foods serve real roles -- structural (in kibble production), energetic, and via fiber for digestive health. Most dogs do perfectly well on diets that include moderate carbohydrates.

How many carbohydrates are in typical dog food?

Most commercial dry dog foods contain roughly 30-60% carbohydrate on a dry matter basis, though this is not listed directly on the label. You can estimate it by subtracting protein, fat, moisture, fiber, and ash percentages from 100. Wet foods are generally lower in carbohydrates than kibble.

Is grain-free dog food lower in carbs?

Not necessarily. Grain-free foods substitute grains with starchy vegetables and legumes (potatoes, peas, lentils), which are also carbohydrate sources. The total carbohydrate content of grain-free kibbles is often similar to grain-inclusive formulas. 'Grain-free' describes the ingredient source, not the carbohydrate level.

Is fiber the same as carbohydrate on a dog food label?

Fiber is a type of carbohydrate, but on pet food labels it is listed separately as 'crude fiber.' The estimated carbohydrate content (not separately listed) includes both digestible starches and sugars as well as fiber. They serve different functions -- digestible carbs provide energy; fiber mainly supports digestive health.
