Dogs metabolize nutrients differently than humans, understanding these differences helps make appropriate dietary choices.
Dogs can produce glucose from protein and fat through gluconeogenesis, meaning they don't strictly require dietary carbohydrates. However, digestible carbohydrates provide readily available energy and can be part of balanced diets.
Protein metabolism in dogs is highly efficient. They can utilize animal proteins very well but have varying abilities to digest plant proteins depending on processing and source.
Fat provides concentrated energy and helps absorb fat-soluble vitamins. Dogs can efficiently metabolize fats, though very high-fat diets may cause digestive upset in some individuals. Essential fatty acids must come from diet as dogs cannot produce them.
Metabolism varies by breed, age, activity level, and individual factors. Small breeds typically have higher metabolic rates per pound than large breeds. Puppies have higher metabolic rates than adults. Spaying/neutering often reduces metabolic rate by 25-30%.
Environmental temperature affects energy needs—dogs burn more calories maintaining body temperature in cold weather. Stress, illness, and healing also increase metabolic demands.
