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.
Watch as Veterinarian Dr. Katy Nelson shares all the basics of building a positive relationship with a puppy. You’ll learn everything from taking care of your puppy’s basic needs to socialization. When all is said and done you’ll learn how a happy puppy makes for a happy owner as well.
Hi, I'm Dr. Katy Nelson with IAMS, and today we're going to talk about how to take care of your puppy. First and foremost, you want to understand and meet your puppy's needs. Here they are in order of importance. Number one: basic health-- water, nutrition specifically formulated for puppies, and sleep. Also, immunizations and regular checkups are recommended. Number two: safety. As with small children, you need to keep your puppy in an environment that is safe for him. Puppies explore with their mouths, and they learn about different textures by gnawing. Also, chewing helps massage their gums. For your puppy's safety, keep things that he or she should not be chewing on out of reach. Number three: psychological. Your puppy's greatest psychological need is to be part of a group and be socialized with other dogs. However, to do this successfully, you need to be a guardian he can depend on. Once your puppy's basic needs are met, you want to understand the way he sees the world, so that you can build a strong relationship. Your puppy does not understand the world you live in, so you cannot expect him to. Two things you need to understand is that to them, everything is edible, and they will lunge at anything exciting—you, kids, guests, and other animals, until you train them not to. Praise him exuberantly to encourage the right behavior. Give him treats, pet him, play with him, and be stern to discourage the wrong behavior—ignore him, stop petting, or stop playing. Most importantly, be patient and consistent. Don't be harsh. Puppies have lots of energy, and it's healthy for them to use it. Periodically, helping your puppy release energy will minimize his urge to dig and chew on things. Spend time out in the yard making him run in short bursts. Go on walks or play fetch. Puppies are used to playing with their brothers and sisters. When they're separated, they're looking for their next playmate. Playing with your puppy will also make him more focused on you, improving your bond and making training easier. It teaches him new behaviors, self-control, and will help him gain self-confidence. Like play, socialization is also fundamental to raising your puppy. This is why socializing your puppy as soon as you bring him home is important for both of you. Socialization teaches your puppy to be calm in stimulating circumstances, and to obey when instructed. It also gets him used to being touched, handled, and even used to having hands and inedible things in and near his mouth, so that he behaves around other people, kids, and his veterinarian. Also, know that puppies are sensitive. They can read facial expressions and emotions. Be consistent about what things your puppy does that make you express happiness. Also, be careful not to give your puppy reason to think he's at blame for negative emotions you have from other areas of your life, like when you've had a bad day at work. Emotions are contagious. The happiest puppies tend to be in the most positive and loving households. I'm Dr. Katy Nelson with IAMS, and I hope that you found this helpful as you welcome your new addition to your family.
