Dogs are also carnivores, although not obligate ones. Although dogs have adapted increasingly over time to the human diet (including carbohydrates!), proteins still remain an essential source of nutrition for them.
Hydration and plenty of proteins are essential to the right diet for our four-legged friend. We do, in fact, recommend supplementing kibble with wet foods, to offer the dog a complete and nourishing meal that is also appetising, because it is always varied.
