Not all small dogs have the same nutritional needs. Giving your dog a food specially formulated for her size and activity level is the easiest way to make sure you’re providing complete and balanced nutrition. Here’s how to provide the right nutrition for your small dog.
Small adult dogs require a food that offers complete nutrients essential for health and vitality. Here’s what to look for:
These ingredients are the keys to nutrition whether you feed dry or wet dog food or give your dog treats.
Small dogs have small mouths and stomachs. You may want to feed your dog a formula with a small bite size for easy chewing. A nutrient-dense food will help make sure she’s absorbing essential nutrients even though her stomach can only accommodate what seems like a small volume of food.
When choosing a food for your small-breed dog, also ask:
Special conditions like these dramatically affect your dog’s nutritional demands.
Less-active dogs and dogs who have been neutered or spayed are prone to weight gain. Controlling your dog’s weight is an important step toward protecting against complications of excess weight, such as diabetes or joint health problems. If you use a weight-control food, look for these ingredients:
Starting in the seventh week of her pregnancy, a mother dog will need to increase her energy intake up to 50% by the time she gives birth and increase it even more when she starts nursing her puppies. Because she may lose her appetite at times, it’s important that she eats a nutrient-dense food. A complete, balanced small-breed puppy formula can give her the extra nutrients she needs.
Unlike larger dogs that are considered mature at age 5, your small dog can remain on an adult diet until age 7. In fact, small-breed dogs tend to live longer and don’t experience age-related changes as early as bigger dogs. However, it is important to make a proactive transition to a specially formulated mature diet, such as IAMS™ ProActive Health™ Mature Adult Small & Toy Breed, so you can help keep your dog healthy and active for years to come.


Antioxidants are nutrients found naturally in the body and in plants such as fruits and vegetables. Common antioxidants include vitamin A, vitamin C, vitamin E, and certain compounds called carotenoids (like lutein and beta-carotene).
As cells function normally in the body, they produce damaged molecules called free radicals. These free radicals are highly unstable and steal components from other cellular molecules, such as fat, protein, or DNA, thereby spreading the damage.
This damage continues in a chain reaction, and entire cells soon become damaged and die. This process is called peroxidation. Peroxidation is useful because it helps the body destroy cells that have outlived their usefulness and kills germs and parasites. However, peroxidation, when left unchecked, also destroys or damages healthy cells.
Antioxidants help prevent widespread cellular destruction by stabilizing free radicals. More important, antioxidants return to the surface of the cell to stabilize, rather than damage, other cellular components.
When there are not enough antioxidants to keep peroxidation in check, free radicals begin damaging healthy cells, which, in turn, can lead to problems. For example, free-radical damage to cells of the immune system can lead to an increased risk of infections.
Because antioxidants play a key role in minimizing damage to human cells, such as those that make up the immune system, research examined the benefits of certain antioxidants on the immune response of dogs. The results of these studies indicated that antioxidants are important in helping dogs maintain a healthy immune system.
