Many people have different answers based on their experiences with dogs. Clearly, the type of dog will determine how much and how frequently you should feed him. Small dogs require much less than a larger dog, but the difference might not be as big as you might think.

It also depends on the age your dog and his condition.

Puppies require a different diet than an older dog, and senior dogs also require special feeding. Puppies and senior dogs will benefit more from smaller feedings spread out over the day rather than one or two large feedings. This will enable their stomachs to handle the food more easily and efficiently.

A geriatric dog can be expected to eat less than an adult dog of his size and breed. This relates to the dog's slowed metabolism and reduced frequency of bathroom visits. It's wise to restrict the amount of protein intake for aged dogs as it is difficult for them to digest and absorb the nutrient value from protein.

Convalescing dogs require smaller, more frequent feedings, too until they regain their strength. If your dog has gone through surgery, start with foods that are easy to digest. Your vet might recommend liquids for the first few days, depending on the type of surgery and your dog's condition. Feed a sick dog 3-4 times a day in small amounts.

As a general rule of thumb, healthy adult dogs do well with two meals a day in the morning and evening. Treats can be provided throughout the day during training or simply as a treat to satisfy your need to bond with your dog.

Make note of how much your dog gets throughout the day to prevent over feeding. It's easy to do when there are several family members running your dog through his paces. Watch table scraps, too, as these can add to your dog's total caloric intake.

Pay attention to any increase in weight that your dog might experience. This is a sure sign that you are overfeeding him, or providing the wrong kind of food. In puppies, a round belly might indicate that they have had sufficient food, but it can also be a sign that they have worms. Do not rely on the look of the belly to determine whether your puppy is sufficiently fed.

It's easy to weigh your puppy while he is small. Get on your bathroom scales and note your own weight. Get off and pick up the puppy. Get back on the scales and take a new measurement. Calculate the difference between the two weights and that will be your puppy's weight. Monitor this regularly to see if he shows much weight gain. Check with your vet or a dog book on your breed to find out what the correct weight should be for your puppy at different ages.

Pay attention to the feeding instructions on whichever dog food you give your dog. This will tell you how much of that particular food to feed him and how frequently.
