If you’ve got a big love for big dogs, IAMS™ has a large-breed puppy formula specially made for their nutritional needs.
Many large-breed puppies have a tendency to grow very quickly. Unfortunately, if this tendency is encouraged by overfeeding, developmental bone problems can occur. To avoid these problems, careful feeding management is necessary. This should include
Our specially formulated large-breed puppy formulas make feeding management easier because they are designed for fast-growing, large-breed puppies (those with an expected adult weight of more than 50 pounds).
A protein level approximating 26% in these formulas promotes healthy body condition and balances the protein with the reduced number of calories in the food. Research has shown that
The protein in our large-breed puppy formulas supports normal skeletal and muscular growth.
Fat contributes more than twice as many calories in a diet as proteins or carbohydrates do. As the fat level increases, the energy content of the diet also increases, making feeding management more difficult for large-breed puppies. Several studies have shown increases in developmental bone problems when a diet was overfed.2, 3
By reducing the fat content of large-breed puppy formulas to about 14%, the metabolizable energy (ME) of the diets can be kept to a low level of about 1,800 kilocalories per pound.

Our large-breed puppy formulas, such as IAMS ProActive Health™ Smart Puppy Large Breed, are made specifically for growing puppies with expected adult weights of 50 pounds or more. These puppy foods are unique because they are formulated with:
Reduced calcium and phosphorus levels with a normal calcium-to-phosphorus ratio to promote proper bone development in rapidly growing large breed puppies.

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.
