The requirements and functions of nutrients in dogs are largely similar to those in cats, with many requirements relaxed: The requirement of arginine in the urea cycle is reduced, as dogs have a functional pyrroline-5-carboxylate synthase. [99] Dogs have a functional delta 6 desaturase, hence no specific need for arachidonic acid. [71]
Vitamins, minerals, fiber, and water do not provide energy, but are required for other reasons. A third class dietary material, fiber (i.e. non-digestible material such as cellulose), seems also to be required, for both mechanical and biochemical reasons, though the exact reasons remain unclear.
Owners should also be mindful as to the energy level of their puppy; high energy level puppies will require more energy and may need to be fed extra amounts of food, just as lower energy puppies may require less food. The 9 point body condition score has been shown to be an effective method for estimating percent body fat in dogs. [9]
Dogs get ample correct nutrition from their natural, normal diet; wild and feral dogs can usually get all the nutrients needed from a diet of whole prey and raw meat. In addition, a human diet is not ideal for a dog: the concept of a "balanced" diet for a facultative carnivore like a dog is not the same as in an omnivorous human.

Organisms obtain nutrients by consuming organic matter, consuming inorganic matter, absorbing light, or some combination of these. Some can produce nutrients internally ...
