Tiny amounts of vitamins are necessary in dogs for normal metabolic functioning. Most vitamins cannot be synthesized in the body, and therefore are essential to obtain in the diet.
Please note that when feeding your dog a complete and balanced diet, it is unnecessary to give a vitamin supplement unless a specific vitamin deficiency is diagnosed by a veterinarian. Due to over supplementation, poisoning due to excess vitamins (hypervitaminosis) is more common these days than vitamin deficiency (hypovitaminosis). Excess vitamin A may result in bone and joint pain, brittle bones and dry skin. Excess vitamin D may result in very dense bones, soft tissue calcification and kidney failure.
Minerals are nutrients that cannot be synthesized by animals and must be provided in the diet. In general, minerals are most important as structural constituents of bones and teeth, for maintaining fluid balance and for their involvement in many metabolic reactions.
A balanced diet is critically important to your dog’s cell maintenance and growth and overall health. Barring any special needs, illness-related deficiencies, or instructions from your vet, your pet should be able to get all the nutrients he or she needs from high-quality commercial pet foods, which are specially formulated with these standards in mind.
But dogs of different ages have different nutritional requirements. So, how much—or how little—should you be feeding your four-legged friend?
Nutrients Your Dog Needs:
Nutrients are substances obtained from food and used by an animal as a source of energy and as part of the metabolic machinery necessary for maintenance and growth. There are the six essential classes of nutrients dogs need for optimum healthy living.
Essential to life, water accounts for between 60 to 70% of an adult pet’s body weight. While food may help meet some of your pet's water needs (dry food has up to 10% moisture, while canned food has up to 78% moisture), pets must have fresh clean water available to them at all times. A deficiency of water may have serious repercussions for pets. A 10% decrease in body water can cause serious illness, while a 15% loss can result in death.
Proteins are the basic building blocks for cells, tissues, organs, enzymes, hormones and antibodies, and are essential for growth, maintenance, reproduction and repair. Proteins can be obtained from a number of sources including animal-based meats such as chicken, lamb, turkey, beef, fish and eggs (which have complete amino acid profiles) and in vegetables, cereals and soy (but these are considered incomplete proteins).
Fats are the most concentrated form of food energy, providing your pet with more than twice the energy of proteins or carbohydrates. Fats are essential in the structure of cells, needed for the production of some hormones, and are required for absorption and utilization of certain vitamins. Fats also provide insulation and protection for internal organs. A deficiency of essential fatty acids (such as linoleic acid) may result in reduced growth or increased skin problems.
Carbohydrates provide energy, play a vital role in the health of the intestine, and are important for reproduction. While there is no minimum carbohydrate requirement, there is a minimum glucose requirement necessary to supply energy to critical organs such as the brain.
Fibers are kinds of carbohydrates that alter the bacterial population in the small intestine, which can help manage chronic diarrhea in dogs. For dogs to obtain the most benefit from fiber, the fiber source must be moderately fermentable. Moderately fermentable fibers—including beet pulp, which is commonly used in dog foods—are best to promote a healthy gut while avoiding the undesirable side effects of highly fermentable fibers, like flatulence and excess mucus.
Other examples of moderately fermentable fibers include brans (corn, rice and wheat) and wheat middlings. Foods that are high in fiber are not good for dogs with high energy requirements, and who are young and growing.
Look For Foods with High Levels of Vitamin E and Beta-Carotene
Antioxidants such as vitamin E and beta-carotene help eliminate free radical particles that can damage body tissues and cause signs of aging. Senior diets for dogs should contain higher levels of these antioxidant compounds. Antioxidants can also increase the effectiveness of the immune system in senior dogs.
Routine care for geriatric pets should involve a consistent daily routine and periodic veterinary examinations to assess the presence or progress of chronic disease. Stressful situations and abrupt changes in daily routines should be avoided. If a drastic change must be made to an older pet's routine, try to minimize stress by introducing the change in a gradual manner.
One of the most common pitfalls dog parents should watch out for is overfeeding. Attempts to shower our dogs with love by means of big meals and lots of tasty treats are sweet, but misguided. In dogs, as with humans, extra weight can lead to health problems. Be sure to indulge your four-legged friend with affection, not food!
Feeding your dog:
How Much Dry Food to Feed Your Puppy
Puppies require up to twice the energy intake of adult dogs and, depending on the breed, will need to be fed a food that contains 25 to 30% protein. Remember, the adult size of a dog is determined genetically—not by how fast the animal grows. Do not overfeed in an attempt to accelerate a puppy’s growth rate.
If they are allowed to overeat, puppies can consume too many calories, grow too rapidly and develop health problems. Small breeds often reach their adult body weight in nine to twelve months. As puppies, its okay to leave dry food out for small them to peck as they wish. But most medium-breed puppies and all large- or giant-breed pups can suffer from bone or joint problems if they eat too much during this stage and benefit most from controlled feeding.
