As your dog reaches his mature years, remember these tips:

• Minimize stress and change. Avoid big moves or changes in your dog's schedule. If you must disrupt a routine, give your dog some added attention to ease the adjustment.
• Give him regular exercise. Take him for two 15-minute walks each day to help maintain muscle tone, enhance circulation, promote digestion, and prevent weight gain.
• Feed him smaller, more frequent meals. Instead of one large portion a day, try two or three smaller meals, which will help your dog burn calories by stimulating his metabolism.
• Take him for routine veterinary checkups and immunizations. Regular dental care and thorough physicals will reveal subtle changes in your dog's health. At home, frequently examine him for any odd-shaped bumps or lumps. If you discover something unusual and it seems to be growing rapidly, call your veterinarian. Early detection and preventive treatment can go a long way toward extending your friend's life.
• Give him great-tasting, premium pet food. As your dog ages, he may become less interested in eating. Make sure he gets tasty, nutrient-dense food that's gentle on his digestion.

As Dr. Michael Hayek, an IAMS™ research nutritionist who specializes in geriatric nutrition, points out, there's still much to learn about canine geriatric nutrition. For now, realize that every animal ages at a different rate and in different ways. Monitor your dog and especially watch for changes at around 7 years of age (5 years for large breeds). If necessary, adjust his diet accordingly. With the help of your veterinarian and responsible pet food manufacturers, your mature pal can live to a comfortable, healthy old age.
