However, your decision should take into account your preferences in terms of taste, cost and nutrition. These foods have a relatively high moisture content that gives them a soft, chewy texture. Because of the high moisture content, they consist of less protein than dry foods - about 16 percent to 25 percent. They cost more per serving than dry foods and have to be fed in larger quantities. Their makeup makes them easy to store, and dogs usually prefer the taste and texture of softer foods.
Canned foods are the softest and most palatable of all dog foods.
They contain roughly 75 percent water, resulting in protein levels of 8 percent to 15 percent, depending on the type of animal tissue used in the food. They deliver 375 to 950 kilocalories per pound, meaning a dog will have to eat more food in order to meet its caloric needs. They cost more per serving than the other types of food and, once the can is opened, the unused food must be refrigerated. When comparing foods, it is important to distinguish between these categories. The serving size for the canned food will be much larger due to the increased amount of water.
