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.
Learn more about how you can help your senior dog manage common health issues associated with aging.
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.*

Giving your dog the right nutrients and a complete, balanced diet does not have to be a head-scratcher. All you need to know is what can a dog eat, how much to feed your dog or puppy, how to feed dogs, how many times to feed a dog, how to handle treats and supplements, etc. And this article tries to answer commonly asked questions on dog feeding.
When deciding which dog food is right for your pet, consider these three factors:
Puppies should be fed three times a day from weaning (3 to 6 weeks) to 4 months of age. After 4 months, they should be fed twice a day. Most dogs should continue to be fed twice a day throughout their life, although some pets do well with one feeding.
The answer to this question depends on your dog’s age, size, and activity level. Feeding guidelines, which list the daily-recommended portion, are included on all IAMS™ packages. Start feeding your dog with this amount and adjust according to its needs. Remember to divide the portion accordingly if you feed more than once a day.
The amount of food you need to feed your puppy depends on 3 main factors — breed, weight, and age. However, you can look at this puppy feeding table that we recommend for puppies:
Puppy | Adult target weight (kg) | Recommended daily feeding (g/day) | ||||
| <3 months | 3-6 months | 6-9 months | 9-12 months | 12-18 months | ||
Toy breed | 1-3 | 15-72 | 32-83 | 37-83 |
| |
| 3-5 | 33-106 | 72-121 | 83-121 | |||
Small breed | 5-8 | 48-151 | 106-172 | 111-172 | 111-170 | Transition to IAMS™ Proactive Health™ Adult Dog Food |
| 8-10 | 69-178 | 151-204 | 170-204 | 170-201 | ||
Medium breed | 10-20 | 82-299 | 178-343 | 201-343 | 201-339 | |
| 20-25 | 137-346 | 299-404 | 339-404 | 339-404 | ||
Large breed | 25-40 | 136-492 | 346-575 | 404-575 | 396-575 | 396-563 |
| 40-50 | 191-509 | 493-675 | 575-681 | 563-681 | 553-676 |
This diet contains 390 kilocalories of metabolizable energy (ME) per 100 gms. Remember to have clean, fresh water available for your dog always.
You should not change your puppy’s food to adult abruptly. Giving your pet time to acclimatise to the new taste of adult food is very important. Also, if you suddenly switch your pup’s food, it can cause digestive problems. Go through this schedule that will help you understand how much to feed your dog and transition your dog’s diet from puppy food to adult food:
If you are wondering how much to feed your puppy by weight and age, check out the weight and age-wise breakdown on when to transition your puppy’s diet to adult food:
Weight range | Age to begin transition |
Small breeds that weigh < 9.07 kgs | 9 and 12 months of age |
Medium breeds that weigh between 9.07 and 22.6 kgs | 12 to 14months of age |
Large breeds that weigh more than 22.6 kgs | 12 to 24 months of age |
While transitioning from adult dog food to senior dog food, it is important to factor in your dog’s weight. Look at this weight table to know when to transition your dog’s food from adult to senior:
Weight range | Age to begin transition |
More than 40.8 kgs | 5 years |
23.1 to 40.8 kgs | 6 years |
9.5 to 23.1 kgs | 7 years |
Up to 9.07 kgs | 7 years |
When changing your dog’s food diet, it’s important to slowly introduce new food. Start by offering your dog’s daily portion in a ratio of 25% new food to 75% current food. During the next three days, gradually increase the amount of new food and decrease the amount of the old food.
If your dog has gained unhealthy weight, make sure to cut down on fats along with increasing regular exercise. We recommend you browse through IAMS™ products and choose dog foods that are low on fat. How much food to feed your dog if they are overweight, is another major concern. You can consult your vet to understand the right amount of food your furry friend needs for each meal.
It’s important to understand that your dog’s nutritional needs change during pregnancy and ensure you feed her nutrition-rich food. For pregnant dogs, we recommend IAMS™ Puppy food as it’s full of proteins that can help your pregnant dog during the gestation period and improve the quality of milk to nourish her puppies post-delivery.
Wet food is an excellent treat that can be fed alone or mixed with dry food. Although IAMS wet dog foods are nutritionally complete and balanced, it is not necessary to offer wet food at every feeding. Our dry foods are formulated with high-quality protein sources such as chicken and contain all the essential nutrients pets need. The crunchy texture of dry food also promotes healthy teeth and gums, and aids in overall good oral hygiene. In addition, some of our dry dog foods contain a dental enhancement to help block tartar buildup on teeth during and after meals.
No. Unlike humans, dogs have fewer taste receptors. Hence, they won’t feel the urge to eat something different every day. In fact, if you find something that suits your dog’s overall health and preferences, stick to that food.
Soaking dry food will ease up the initial job of the digestive enzymes. While water will not change its nutritional value, the food should be eaten relatively soon. Moreover, ensure that the leftover portion is discarded to avoid spoilage. We recommend providing your dog with IAMS™ dry food because it is beneficial to your dog’s dental health as well.
No. Cats and dogs have different nutritional requirements. Moreover, cat foods are made with higher fat levels, which can be harmful to a dog. While it is okay for dogs and cats to sniff and lick some food from each other’s bowl, you shouldn’t let dogs eat cat food.
We recommend feeding your dog approximately two to four small biscuits per cup of food. Keep in mind that when you add biscuits to your dog’s daily diet, this increases its daily calorie intake, so you should reduce the amount of food you feed. Check the calorie content of the biscuit since biscuits vary in size and formulation.
Since IAMS™ dog foods are nutritionally complete and balanced, adding more vitamins, minerals or oils can disrupt the balance our dog food provides. The reason why you provide your dog with a high-quality product is that it has been developed to offer nourishment in proper ratios and ensure optimal nutrition. Hence, nothing needs to be added.
Protein is one of the essential elements that should be a part of your dog’s diet. Including protein in your dog’s diet will strengthen its muscles, ligaments, and cartilages. A protein-rich food also brings about a healthy shine to your dog’s coat!
It is important to maintain a feeding schedule for dogs so that they are conditioned to expect food at that time and avoid irregular snacking in between.
You should never feed your dog home-baked goods, candy, gum, chocolate, limes, onion, and grapes. They can harm your dog’s digestive tract and cause infections as well.
IAMS™ dog food is full of key nutrients that your dog needs for its healthy growth. The basic ingredients in our food include chicken, fish oil, beet pulp, wholesome grains, and natural prebiotic.
