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.


The Association of American Feed Control Officials (AAFCO) was formed in 1909 to establish a framework for uniform regulation of the feed industry. Although not a government agency, AAFCO operates within the guidelines of federal and state legislation including laws administered by the Food and Drug Administration (FDA) and the U.S. Department of Agriculture (USDA).
AAFCO establishes standards or models for regulations aimed at ensuring that manufacturers provide clear, accurate, and consistent information about animal feed, including pet food.
Every year AAFCO issues an official publication called the AAFCO Manual. This manual, in addition to listing ingredient definitions and feed terms, addresses labeling issues such as label format, ingredient lists, nutrition claims, and guaranteed analysis.
These model regulations are different than laws. However a large number of state governments have adopted AAFCO pet food model regulations into state law.
The “AAFCO statement of nutritional adequacy or purpose,” also called a “nutrition claim” or “complete and balanced statement,” identifies which life stage and/or lifestyle the product has been approved for. Under AAFCO regulations, this statement must be substantiated by the manufacturer.
AAFCO recognizes three methods for substantiating the claim:
AAFCO has outlined very specific protocols, or guidelines, for conducting feeding tests. The protocols specify test criteria including such things as:
Each life stage has its own protocol. Life stages are the same for both dogs and cats and are defined as:
A pet food with an 'All Life Stages' claim can be used from weaning through adulthood. This claim is considered an unqualified (absolute) representation of nutritional adequacy. If substantiated through feeding trials, the protocol for gestation/lactation and growth must be performed sequentially, using the same group of animals.
AAFCO regulations state that specific wording must be used when a diet is intended for special nutritional or dietary needs that require the involvement of a veterinarian for diagnosis, management, and follow-up.
Understanding the AAFCO statements for nutritional adequacy can help customers choose a high-quality diet that provides complete and balanced nutrition for the appropriate life stage of their dog or cat.
