Unlike larger-breed dogs that are considered mature at age 5, medium-breed dogs are usually called mature or senior at age 7. By this time, their nutritional requirements are changing. You can help keep your medium-breed dog active, happy and healthy with a specially formulated mature or senior diet that delivers highly digestible, enhanced nutrition.
Your dog might be aging in a number of ways. He may have a dull, dry coat and flaky skin, declining activity or weight gain, decreased immune system response, more frequent intestinal problems, joint stiffness and a loss of lean muscle mass. It’s true that a mature or senior dog generally needs fewer calories, but to address special mature or senior concerns, your dog still needs high-quality protein and carefully balanced nutrients.
What your medium-breed dog needs is a high-quality, balanced maintenance food formulated for his changing metabolism. Look for options with these age-essential dietary components:
These ingredients are the keys to mature or senior nutrition whether you feed dry or wet dog food or give your dog treats.

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.
