First, select the food that is most suited to your pet. If you have a small dog, it would be pretty stupid to give him food for large breeds. In addition, we must remember the age of the dog, as well as the type lifestyle he is comfortable to adapt. In case you have difficulty in choosing, it is recommended to consult a veterinarian. To select the dog food: dry and canned. The use of dry food helps cleanse the teeth, thus reducing the risk of gum disease and tartar.
To force the dog on dry food should be gradual. In the first two or three days, replace one-quarter of the usual food to dry food but remember not to mix them. So let them have dry food, for example, only for breakfast. See how the dog reacts to the food. If you see any side effects, keep on changing the diet when you realize that the food is good for his health.
The next three or four days, increase the amount of dry food and just enough down the same portion of a natural food. Give the dog more water. A week can fully translate the dog on dry food.
