Some nutrients can be stored internally (e.g. the fat soluble vitamins), while others are required more or less continuously. Poor health can be caused by a lack of required nutrients or, in extreme cases, too much of a required nutrient.
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]

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.

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]
