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.
 
  
 Between 25 and 40% of dogs are overweight, but often, owners don't know it until they take their dog to the veterinarian for another reason. Yet, even veterinarians can't tell if a dog is fat just by its weight. Ideal weight varies by breed, and quite widely within breeds. There's no ideal weight chart for all dogs!
You can judge your dog's condition by placing your hands on each side of his rib cage. Are the ribs protruding? Your dog may be too thin. Can you feel individual ribs easily, and is your dog's abdomen slightly tucked up when viewed from the side? That's the sign of ideal weight. If you can't feel the ribs easily, your dog has no waist, and his abdomen drags, he's too fat. Your veterinarian can help you further evaluate your dog's weight.
Before beginning any weight loss program with your dog, discuss it with your veterinarian.
You can begin your dog's weight-loss program by reducing caloric intake by 25% of his maintenance intake, and then decrease it by 10% increments every two to three weeks until a 1% weight loss per week is achieved. This means that, if your dog weighs 15 pounds, a 1% loss would be about 2-1/2 ounces.
If you feed one large meal a day or keep food available at all times, try dividing the daily ration into several small meals (at least two meals a day) and pick up what has not been eaten 30 minutes after each meal.
Dogs gain weight for the same reason that people do—they eat more calories than they use. Today's dogs share another problem with their parents: lack of activity. Most parents are gone all day and come home too tired to play with the dog.
Also, as dogs age, or after they are spayed or neutered, their metabolism might slow causing them to require less food.
Another reason for weight gain is frequent, high-calorie treats. Sometimes, more than one family member is feeding the dog, and the dog sure isn't telling!
Losing weight isn't easy. Changing habits is the key. Here are some ways you can help:
Determine who feeds the dog what and when. (Don't be embarrassed to admit you give your dog treats. Dogs are expert beggars.)
Substitute affection for treats. Give a pat or throw a ball when he noses your hand.
Take your dog for a walk more often. Even 10 minutes a day can help.
Feed him more often. It takes energy to digest food. Dividing your dog's daily ration into two or three feedings will help.
Reducing your dog's regular food amount by 25% should bring results.
If your dog is more than 15% overweight, your veterinarian might recommend a special food. Diet foods should be low in fat (under 20% of calories from fat).
Your goal is to help your dog be healthier, so select his food carefully. Some diet foods just add fiber to help the dog feel full. This can result in reduced digestibility, large stool volume, frequent trips to the backyard, and decreased skin and coat condition because the dog isn't getting enough fat and nutrients.
Find a food, such as IAMS™ ProActive Health™ Adult Healthy Weight, that has normal fiber levels to keep your dog's digestive system working properly. It should have high-quality protein so your dog doesn't lose muscle tone and essential fatty acids to help keep his skin flexible and coat glossy throughout the dieting process. After your dog reaches ideal weight, select a maintenance food to keep weight steady.
Obesity is a common problem in dogs. Identifying the causes and following a total weight management program can result in controlled weight loss and maintenance. A total weight management program includes evaluating your dog, then modifying behaviors and successful dog weight control.
 
Definition of obesity
Obesity is defined as an increase in body weight beyond the limitation of skeletal and physical requirements, resulting from an accumulation of excess body fat.
 
Causes of obesity
Obesity is caused when caloric intake exceeds caloric expenditure. This simply means that a dog eats more energy (calories) than he uses and stores the excess energy.
 
Factors contributing to obesity
Fat and carbohydrates
Dogs use fat as their primary energy source. An overweight dog stores fat more easily if the calories are consumed in the form of fat than if they are from carbohydrates. An overweight or obese dog should be fed a low-fat, high-carbohydrate diet to restrict calories available from fat, which is important for dog weight control.
 
Fiber and fatty acids
A normal fiber level, provided in a moderately fermentable fiber source, helps create and maintain healthy digestion. This is especially important for the dog on a diet. Some weight-loss foods for dogs dilute calories with high levels of fiber. High-fiber foods may reduce the digestibility and absorption of many nutrients, including fat. These foods reduce weight by providing what would be considered poor-quality nutrition. These high-fiber diets also result in large, frequent stools and decreased skin and coat condition. Dog foods such as IAMS™ ProActive Health™ Adult Weight Control, which provide essential fatty acids like those found in vitamin-rich fish oils, help maintain your dog's healthy skin and coat despite lowered fat levels.
 
Gradual Weight Loss
The goal of a good weight management program should be gradual weight loss. Dogs should lose 1% to 2% of their initial weight per week. This can be achieved by reducing the caloric intake by 30% to 50% of maintenance.
 
A total weight management program can lead to successful weight loss in the obese dog. Before beginning any weight-loss program with your dog, discuss it with your veterinarian. Remember, your support is essential to your dog's weight-control success.
