Different dogs do better on different types of dog food. Whether you choose a canned food, dry dog food, or other type of dog food depends not only on your dog's needs but also on your budget, what's most convenient to you and how you feel about certain types of ingredients in the dog food. Consider all these when you are choosing a dog food. If you have leftover canned food, do not leave it in the can. Place it in a plastic storage container or in a plastic storage bag with all the air squeezed out. Refrigerate it until the next use.

Among all kinds of dog food, dogs like the taste of canned food. Canned dog food has a long shelf life until it's opened. On the down side, dog canned food is expensive, and it must be refrigerated after it's opened. Dry dog food is easy to scoop out, measure and serve. Dry dog food is less expensive than canned food and doesn't need to be refrigerated even after it's opened. And dogs often like the crunchy texture. Dry dog food doesn't have much of a down side (perhaps a bit heaty), although most dogs prefer canned dog food.

Recently, manufacturers have begun preparing frozen and dehydrated foods for dogs. Frozen diets or frozen dog food are prepared fresh, made into rolls, cubes, or loaves and flash frozen so they don't need artificial preservatives. Dehydrated dog food have all the water removed from them. Dehydrated dog food are prepared at a temperature low enough to preserve the value of the vitamins, minerals and other nutrients yet high enough to kill any bacteria. Just mix the dehydrated dog food with warm water and they are ready to feed. Dehydrated dog food has long shelf life and easy storage of canned dog food and dry dog food.

Key note
Remember that too much of a good thing can be harmful. If your dog is eating a food that's complete and balanced, avoid giving him vitamin or mineral supplements without first checking with your vet or a vet nutritionist.
