Physiological condition, rather than chronological age, determines whether a dog is mature. Aging begins when the body's systems start to slow down, when cells deteriorate faster than the body can repair them. Though large breeds tend to age faster than smaller breeds, the mature years generally begin at around 7 years (5 years for large breeds). If you feed your dog a diet designed to address the nutritional needs of his age, you can best maintain his overall health and well-being.
As your dog ages, it is important to detect and address with his veterinarian the telltale signs of aging or disease: a dull, dry coat and flaky skin, joint stiffness, energy loss, weight gain, increased water intake, digestive problems, and frequent constipation. These signs, among others, may be caused either by normal wear-and-tear or perhaps by the onset of disease. In any case, detecting and addressing them early may give your dog a greater chance to stay active and healthy.
When and how your dog responds to the aging process has a lot to do with genetics and environment, but nutrition plays an equally important role. The quality of food and its ability to maintain and nourish your dog's cells can help promote a long, healthy life.
As your dog ages and his systems become less efficient, he relies increasingly on the food you provide to make up for his body's shortfalls. According to Michael Hayek, PhD, an IAMS research nutritionist who specializes in geriatric nutrition, 'Aging dogs need the same nutrients as younger dogs; however, the quantity or the way the nutrients are provided may change.'
Here's what you need to know about your dog’s health as he matures from 1 to 8 years:
Your dog is growing up. Louise Murray, DVM, director of the ASPCA's Bergh Memorial Animal Hospital in New York City and author of Vet Confidential (Ballantine, 2008), gives advice on how to keep your dog in tip-top shape.
Adult Dog Health: Preventive Health. Even if your dog appears fit, see your veterinarian once a year for a checkup. 'Most health problems are more readily and less expensively addressed if you catch them early,' Murray says. What's more, your vet can detect problems that you might miss. You can also stay up to date on vaccination boosters.
Adult Dog Health: Flea, Tick, and Heartworm Medicines. Continue to use preventive medicines. Talk to your veterinarian if you've moved or if your lifestyle has changed to make sure you are using the products best suited for your dog.
Adult Dog Health: Diet. Your pet needs the right food for optimal health. Check with your vet about adjusting the type and amount of food that your dog eats.
Adult Dog Health: Dental Health. If you haven't done so already, get in the habit of cleaning your dog's teeth daily. 'Animals who get gingivitis or inflammation of the gums can end up with problems of the kidneys and the heart,' Murray explains. Get your dog accustomed to having your fingers and hands around her mouth. At the pet store, you'll find dog toothbrushes and finger brushes as well as dog toothpaste.
Adult Dog Health: Weight Gain/Loss. When your dog steps on the scale at her annual visit, weight gain (rather than loss) is more likely to be the problem. Meals usually are not the culprit. It's the things, such as biscuits and human food, she gets in between. 'It all adds up,' Murray says. As your pet gets older, she becomes less active, which can contribute to weight gain and a host of other problems (diabetes, arthritis, and breathing trouble, for instance). But there's another reason to keep an eye on the scale: Weight loss might signal an underlying health problem.
