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.
Antioxidants are nutrients found naturally in the body and in plants such as fruits and vegetables. Common antioxidants include vitamin A, vitamin C, vitamin E, and certain compounds called carotenoids (like lutein and beta-carotene).
As cells function normally in the body, they produce damaged molecules called free radicals. These free radicals are highly unstable and steal components from other cellular molecules, such as fat, protein, or DNA, thereby spreading the damage.
This damage continues in a chain reaction, and entire cells soon become damaged and die. This process is called peroxidation. Peroxidation is useful because it helps the body destroy cells that have outlived their usefulness and kills germs and parasites. However, peroxidation, when left unchecked, also destroys or damages healthy cells.
Antioxidants help prevent widespread cellular destruction by stabilizing free radicals. More important, antioxidants return to the surface of the cell to stabilize, rather than damage, other cellular components.
When there are not enough antioxidants to keep peroxidation in check, free radicals begin damaging healthy cells, which, in turn, can lead to problems. For example, free-radical damage to cells of the immune system can lead to an increased risk of infections.
Because antioxidants play a key role in minimizing damage to human cells, such as those that make up the immune system, research examined the benefits of certain antioxidants on the immune response of dogs. The results of these studies indicated that antioxidants are important in helping dogs maintain a healthy immune system.
