Does your mature dog sniff at his bowl and walk away instead of digging in? You may think he’s just being picky, but it’s important to keep an eye on how much he’s eating — especially if he’s a senior. While age-related diminishment of the senses of smell and taste may account for some of his disinterest in food, appetite loss can also indicate a serious medical problem.
“It’s important to give your dog enough calories because weight loss can be debilitating to senior pets,” says Wendy Brooks, D.V.M., who warns that a loss in appetite should be mentioned to your vet. A good rule of thumb: If your pet hasn’t eaten in a day, make a visit to the vet. Here are six ways to entice your canine friend with a nourishing meal.

Many animals find canned food more palatable because they like the taste and texture, Brooks says. You can top their favorite dry food with room-temperature wet food.
Dogs like a warm or room-temperature (not hot or cold) meal. Avoid serving him day-old wet food from the refrigerator, and keep his food away from heat. Another reason he might not be eating: It's too hot outside.
Dogs prefer consistency when it comes to their food. Don't change every day, but try a new flavor, such as lamb or chicken, and see if he responds (it may trigger his sense of smell). To avoid an upset stomach, introduce a new food by mixing it with his old food in equal increments each day.
Common mature-dog health issues, such as arthritis or joint pain, can make it difficult for him to access his bowls. Keep food and water where he spends most of his time. Put a water bowl on all floors of the house, too.
Older pets are at a higher risk of dehydration. Provide a clean bowl with fresh water at all times. It will help prevent disease, such as a kidney condition, and aid in digestion.
Dogs are people pleasers. If you see him eating, give him a little verbal reward. He'll know it makes you happy and will repeat the behavior.
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.
