Grain-free? Why?
Each dog has different dietary needs. That is why people are always looking for the best feed for their pet. Cheap dog food often contains a lot of grain. Grain is used as a filler, since it is much cheaper than meat. It is true that grains are a good source of carbohydrates. However, dogs have more trouble digesting grains.
Grain-free dog food has the benefit of reducing the odds of an allergic reaction in hypersensitive dogs. It can be tricky to figure out whether their allergic reaction is due to eating grain. Allergic reactions a dog can experience include itchiness, bald spots, loss of hair, etc. It is recommended to feed grain-free if dogs show these symptoms. Grain-free feeding is an easy way to see how a dog responds to it.
The grain contained in dog food is not always bad. If a dog has no allergies and no trouble digesting it, eating grain is harmless. However, the odds keep rising that dogs develop stomach and intestinal issues and allergies if they keep eating grain-rich products.
That is why a dog benefits from a healthy diet. This is a diet with many high-grade proteins, preferably from meat or fish. A dog also requires healthy fatty acids, vitamins and minerals.
