The different types of dog food explained
Dog food is substance made from either plant or from animal parts. The foods given to dogs as an extra privilege as opposed to their meals and are usually referred to as dog treats.
Their notion is that dogs have naturally lived off this type of diet for hundreds of years and that their bodies are adapted to ingest these types of contents. They believe that the commercial foods that have just came into their food chain within the last century or so are actually harmful to their health because they don’t contain the right nutrients and that the dog’s body is not properly nourished when they eat such substances. Still, the vast majority of people still buy the commercialized premade foods for their canine friends.
The commercialized dog foods which can be classified into three categories according to their water content: Wet, dry, and semi moist.
Wet dog foods are normally canned. It also tends to contain higher amounts or proteins and fats compared to that of the other two types of foods, but since it contains so much moisture, the actually protein and fat is lower because of the dilution. Also, wet dog foods are commonly sterilized, so dog owners have fewer worries about contamination.
Next are the dry and semi moisture dog food types. Pound for pound, the dried type of dog food is the most least expensive type of food for your dogs.
Dried dog foods typically contain approximately 8% of moisture. It also tends to keep longer then that of wet dog foods. The individual pellets of dog foods are known as kibbles and are made by two different processes, baking and extrusion. What happens during the extrusion procedure is that raw materials or dough like substance is taken and placed into an expander while at the same time either hot steam or boiling water is added to pasteurize it.
When the substance is transferred from the expander a puff like substance remains and is then dehydrated and covered with grease and oils to help preserve the food substances. Vitamins are also added to the food substance as well. If this material is exposed to the air for long periods of time then the material will get spoiled and will lose most of its nutritional value.
