According to Iams Dog Food company, here's what you need to know as your dog matures.

Your dog is growing up. Louise Murray, D.V.M., 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 her 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 with vaccination boosters.

Adult Dog Health: Flea, tick and heartworm medicines. Continue to use the 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 are usually not the culprit. It's what she gets in between, like biscuits and human food. "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 problems (diabetes, arthritis and trouble breathing, for instance). But there's another reason to keep an eye on the scale: Weight loss may signal an underlying health problem.
