There is no diet that is suitable for every dog, it is a case of trial and error finding what suits you and your dog.Apart from the obvious lifestage feeding (puppy - adult - senior) there are several different ways of feeding him. There are several essentials dogs require.PROTEIN
A dog cannot survive without protein, protein supplys 10 essential amino acids all dogs require that they cannot produce on their own. An adult dog should have 10% of their total calori intake from protein.FATS
Fats and fatty acids are another essential these are obtained from either animal fats or plant seed oils. Fats are the best source of energy for him, they also keep the skin and coat healthy.CARBOHYDRATES
These work along the protein and fats to supply energy, they are supplied by cereal or plant foodstuffs.VITAMINS AND MINERALS
Deficiency in vitamins can cause health problems for example Vitamin D deficiency can cause rickets. There are 12 essential minerals that all have a specific job to do.
Dry food is the most economical type of commercial dog food, and this is the reason that many owners chose it for their dog. It also lasts for a long time and does not need to be refrigerated. Dry food can also help to keep your dog's teeth healthy, since chewing crunchy dry food helps to reduce tartar buildup. When it comes to choosing a specific dry food, read the ingredients carefully, and choose a brand that uses wholesome food as its primary ingredientRAW FOOD
A raw diet consists of raw meat, preferably with some bones (never cooked bones, only raw) and organs mixed in, as bones are a natural source of phosphorus and calcium. This type of diet works well for many dogs, since dogs have short intestinal tracts and strong stomach acids, both of which make it easy for them to consume and digest raw food. Before transitioning your dog to a raw diet, talk to your veterinarian about the benefits and risks.SEMI-MOIST FOOD
Commercial dog foods shaped like pork chops, burgers, or other meaty foods are called semi-moist foods. These kinds of foods are the least nutritional of all dog foods and contain many artificial flavors and colorings. They can be given to your dog as an occasional treat, but they should not be considered a diet in themselves, as they do not provide the nutrition that your pup requires.CANNED/WET FOOD
Most dogs love canned, or wet, food, and it has a long shelf life, and is easy to find at any supermarket, but it can be expensive. For some owners, it's definitely worth the expense, but not every brand of commercial canned food provides the protein that your pup needs. The real question is how much digestible protein it provides. Indigestible protein will pass through your dog's system without being broken down into absorbable nutrients, so it's pretty much useless to him.
Also, most canned food is about 75 percent water. The higher the water content, the less nutrient content, so the more food your dog must consume in order to get the nutritional value his body needs. If you decide to feed your dog canned food, it's best to go with a kind that's labeled "100% nutritionally complete."Home Cooked
Some dog owners value the ability to be in complete control of their dog's diet. A home-cooked diet allows the owner to know for certain exactly what is in every thing her dog eats and to be absolutely sure that his nutritional needs are being met. Feeding your dog a home-cooked diet is time consuming and expensive, but many owners think the extra effort is worth the peace of mind they gain. If you decide to feed your dog a home-cooked diet, get well acquainted with canine nutrition so you can be sure your dog is not missing out on any vital nutrients.
