Unlike larger-breed dogs that are considered mature or senior at age 5, small-breed dogs usually don’t experience age-related changes as early. But by age 7, your small dog is mature or senior, and his nutritional requirements are changing. You can help keep your dog active, happy and healthy with a specially formulated mature diet that delivers highly digestible, enhanced nutrition.
The changes your small dog is going through affect him in many ways. You may notice a dull, dry coat and flaky skin, energy loss or weight gain, more frequent intestinal problems, joint stiffness and a loss of lean muscle mass. It’s true that an aging dog may require fewer calories, but your mature or senior dog still needs high-quality protein and carefully balanced nutrients.
What your dog needs is a high-quality, balanced maintenance food formulated for a small dog’s changing metabolism. Look for options with these age-essential nutrients:
These ingredients are the keys to mature nutrition whether you feed dry or wet dog food or give your dog treats.
Additionally, small dogs have small mouths and small stomachs. A nutrient-dense mature formula with smaller kibble may help make food easier for your dog to chew.
Older, less-active dogs are prone to weight gain. Keeping your dog at a healthy weight can help minimize the risk of developing diabetes or joint stress. Your dog can benefit from a weight-control diet with these key ingredients:
While your mature or senior dog’s nutritional needs may be changing, that doesn’t mean he doesn’t have many active, happy years ahead. Make sure your dog can make the most of them by feeding him a proper diet designed for mature small-breed dogs.


Low-cost food might be better for your wallet, but it can be a raw deal for your dog, because he may not get the nutrition he needs. Premium foods, such as IAMS™ ProActive Health™ Smart Puppy Original , make sense both nutritionally (because of consistent, high-quality ingredients) and economically because they provide:
The investment in a premium food might initially cost more per bag, but because these high-quality formulas are high in nutrient density, your dog may need less food, which can offset the higher cost per unit of weight. On a cost-per-feeding basis, look at how much you feed each day as opposed to how much the bag costs, because nutrient and energy density will generally be lower for a low-cost food compared with premium foods.
With budget-priced formulas, the emphasis is on production and ingredient costs. Two bags of the same least-cost formulated food can have different ingredients and/or levels of ingredients. Plus, those ingredients may vary significantly in digestibility. This means, simply, that you may need to feed more just to equal the nutrition offered by a smaller amount of a premium dog food formula.
High-quality, complete, and balanced premium dog foods such as the IAMS brands are specifically designed to provide your dog with a food that has:
To determine how much food to give your dog, check the daily feeding recommendations set by the pet food manufacturer and read the label. To calculate portion sizes, divide the total daily recommended amount by the number of times (usually two for adult dogs) you plan to feed your dog.
To tell if your dog is at a healthy weight, move your hands along his sides. If you can feel his ribs, he's about right. Or, look down at him when you're directly above him. You should be able to see a waistline.
If he's gaining or losing a lot of weight, slightly decrease or increase his daily intake and weigh him in another week. If you have specific concerns about your dog's weight, talk to your veterinarian. He or she can assess your dog's needs and make a feeding recommendation.
Once you've decided on a premium formula, you have another choice to make: dry or moist. And what about biscuits?
Premium dry dog food gives you the best value and convenience, while fortifying your dog with high-quality nutrition. Premium dry foods come in a number of bag sizes and formulas suited to size, life stage, and activity level. Dry food also helps keep teeth clean, and it stays fresh for a long time if you store it properly.
Wet foods from IAMS provide 100% complete nutrition. IAMS ProActive Health Puppy Biscuits make great treats and rewards and can add taste variety to your new dog's diet.
