Small-breed dogs tend to have higher metabolism rates than their larger counterparts, which means they need a puppy feeding diet specifically designed for them. 'Small-breed dog food formulas are created to give your dog the right balance of nutrients,' says Debra Eldredge, DVM, a veterinarian in upstate New York and coauthor of The Dog Owner's Home Veterinary Handbook (Howell House). Here's what you need to know to feed your small-breed pooch.
The guidelines on the package are a great starting point, Eldredge says, but 'you have to customize [them] for your dog.' For instance, her family has three dogs who all weigh almost the same. But, one is getting twice as much food as the other two, and she's thin. 'She just burns it up,' Eldredge says. Your dog's breed and activity levels will affect how much food she needs.
Small-breed puppies, especially toy breeds, can be prone to hypoglycemia. To keep your dog’s blood sugar levels up, you might have to feed her more frequently and up the calories, Eldredge says.
Small-breed puppies grow quickly, so during the first six months, they need to eat more food and eat more frequently, generally three to four times a day. After six months, feeding two meals a day is usually sufficient. As your dog gets older and less active, her nutritional needs change, and she may need a formula for mature dogs. Her new food will generally have more protein and fewer calories.
Smaller dogs have smaller mouths and teeth, so their food is usually made in a smaller bite size, which is easier for them to chew and swallow.
Don't leave your dog's food out all day. Instead, pick it up after 10 or 20 minutes, Eldredge says. If food is available all day, she may eat out of boredom.
With dog food, your pet is on a balanced diet. Feeding her human food may throw off that balance. The occasional taste of chicken or eggs is okay, but don't make it a daily habit.
Obesity in dogs is a more common problem than you might think. Between 25% and 40% of dogs are overweight, but often, owners don’t realize it until they take their dog to the veterinarian for another reason. Yet even vets can’t tell if a dog is obese by their weight alone. Ideal weight varies by breed, and quite widely within breeds.(Did you know, for instance, that Labrador retrievers, dachshunds and beagles areall prone to obesity?) In short, there’s no ideal healthy weight chart for all dogs!
The good news is that if your dog is overweight, there are a number of ways to help them reach a healthy weight. Don’t underestimate the power of daily walks and a weight management dog diet — IAMS™ Adult Healthy Weight can help return your dog to a healthy weight, providing a path to help keep them fit for life.

Can you feel individual ribs easily? Is your dog’s abdomen slightly tucked up whenviewed from the side? That’s a sign your dog is at their ideal weight.
If you can't feel the ribs easily, your dog has no waist and their abdomen drags,your pup is carrying extra weight. Your veterinarian can help you further evaluateyour dog’s condition and determine their ideal weight.
Dogs gain weight for the same reason people do: They eat more calories than theyuse. Today’s dogs share another problem with their human parents: lack of activity.Many pet parents work all day and are too tired to play with their dog afterward.
Dogs’ metabolisms might slow as they age or after they’re spayed or neutered,which means they require less food. Another common reason for weight gain isfrequently eating high-calorie treats. Sometimes more than one family member isfeeding the dog, and the dog sure isn’t telling!
Other factors that could contribute to canine obesity include:
If you suspect that your dog is overweight or obese, the !rst step is to set up anappointment with your veterinarian so they can evaluate their condition. Likewise,before beginning any weight loss program with your dog, make sure to discuss itwith your vet.
If your dog is overweight, it’s time to implement a weight-management regimen. Ifyou usually feed one large meal a day or keep food available at all times, try adifferent dog-feeding schedule by dividing the daily ration into several small meals— at least two meals a day. It takes energy to digest food, and dividing your dog’sdaily ration into separate feedings will help. If your dog leaves any food in theirbowl, pick it up 30 minutes after each meal.

Your goal is to help your dog be healthier, so select their food carefully. Payattention to the ratio of fat, !ber, protein, carbohydrates and special ingredients inyour dog’s weight-management food:
After your dog reaches their ideal weight, select a maintenance food to keep theirweight steady.
