In the past, veterinarians recommended diets for senior dogs largely based on the nutritional management of diseases common to the aging process. Research, however, has shown that special nutrition can help manage body-condition problems in aging dogs, such as obesity and loss of muscle mass. Senior dogs also benefit from special nutrition to help maintain bone and joint health.

Senior dogs tend to gain weight, despite consuming fewer calories, due to changes in their metabolic rate. Therefore, they can benefit from eating a diet with reduced fat levels and lower caloric density than adult maintenance foods.
Recent IAMS™ research in dogs also indicates that L-carnitine — a vitamin-like compound made in the body from the amino acids found in red meats, fish, chicken and milk — can help reduce weight in overweight dogs by escorting fat into cellular mitochondria where it is turned into energy.
Protein is the building block of muscle tissues. It is important for maintenance of muscle tissues, muscle strength and mobility. Recent research conducted by The IAMS Company has shown that senior dogs that eat a higher-protein diet better maintain muscle protein stores. By providing optimal protein levels from muscle maintenance, we can help senior dogs continue being physically active.
This research is contrary to conventional opinion that senior dog foods should contain lower protein levels than adult maintenance formulas to avoid progressive decrease in kidney function. However, senior dogs fed a high-protein diet had stable renal function and a lower death rate than dogs fed a lower-protein diet.*
During the aging process, cartilage between joints often begins deteriorating. Nutritional management can help maintain healthy bones and joints and mobility in dogs in several ways:
Some pet-food manufacturers have endorsed reduced levels of calcium and phosphorus based on the belief that excesses of these minerals are harmful to the kidneys. However, research has shown that no damaging accumulation of calcium or phosphorus was found in the kidneys of older dogs fed diets containing maintenance levels of calcium and phosphorus for four years.*

Adrena Wilhelm from Canine Companions for Independence shows you how you can teach your dog to speak and be quiet on command. She also provides effective techniques for teaching your dog to not bark when the doorbell rings and when other dogs are near.
Hi. I'm Adrena Wilhelm from Canine Companions for Independence on behalf of IAMS. Today, we're going to learn how to teach your dog to stop barking. It may sound nonsensical. But to stop your dog from barking, first, teach him to bark on command. Give your dog the command to speak. Have someone immediately make a noise, such as knocking on the door that is sure to make your dog bark. Let him bark two or three times. Then, stick a tasty treat in front of his nose. When he stops barking to sniff the treat, praise him and give him the treat. Repeat until he starts barking as soon as you say speak. Once your dog can reliably bark on command, move on to the quiet command. Teach your dog that barking is OK until told to be quiet. Simultaneously, hold a treat in front of your dog's nose. Most dogs get quiet immediately because they can't sniff and lick the treat while barking at the same time. Praise your dog continuously during his quiet time with petting and words of encouragement. When your dog makes a mistake and barks, and he will, reprimand him immediately. Never strike your dog, but do something that will catch his attention, such as clapping loudly. As soon as your dog stops barking, you must instantly reward him. If you're still having trouble, then you may need to spend some time working with your dog on specific barking situations. Here are a few of the more common ones. If your dog is in his crate or confined to a room behind a baby gate or other barrier, he may bark because he wants to be with you. But if that's not always possible, then you'll need to train him to stay quiet. Next time, he's barking uncontrollably in his more confined space, try this. Start by turning your back and ignoring him. Whenever he stops barking, turn and praise him. Give him a treat and make a game of it. As he catches on that being quiet gets him a treat, lengthen the amount of time that he must remain quiet before being rewarded. Dogs that are afraid of other dogs will often bark at them. Have a friend with a dog stand out of sight far enough away that you know your dog won't bark at the other dog. As soon as the friend and dog come into view, start feeding your dog lots of treats. Keep feeding treats until the friend and dog are out of sight. Ask your friend and her dog to gradually walk closer. Don't try to progress too quickly. It may take days or weeks before your dog can pay attention to you and the treats without barking at the other dog. When the doorbell rings, your dog alerts you to the presence of an intruder by barking wildly. Once you've taught your dog the quiet command in a calm environment, practice in increasingly distracting situations. Teach your dog to react to the doorbell by going to a special place and laying quietly while the intruder comes into the house. Start by tossing a treat on his mat and telling him go to your place. Have him go to his place before you give him the treat. When he's reliably going to his mat to earn a treat, up the ante by opening the door while he's on his mat. If he gets up, close the door immediately. Repeat until he stays on the mat while the door is open. Then, increase the difficulty by having someone ring the doorbell while your dog is on his mat. Reward him if he stays in his place. Try these techniques to stop your dog from barking. All of them can be successful, but don't expect miracles overnight. The longer your dog has been practicing the barking behavior, the longer it will take for him to change his ways. Let's recap. First, teach your dog to speak or bark on command. Once he has that down, teach him to be quiet on command. Use treats and praise to help get the desired outcome. And lastly, be patient and consistent in training. Don't expect overnight changes.
