A Dog's Nutritional Needs From Puppy to Senior Years

When you first adopted your dog, you took the time to research and speak with their veterinarian about dog nutritional requirements before choosing what you'd feed them. You know to never share table scraps with your pet, but do you know that as your dog ages, their nutritional needs will shift? A lifestage dog food will grow with your dog, but it's important that you understand what your furry family member needs from their puppy to senior years.

What Are Dog Nutritional Requirements?

Nutrients are substances that are obtained from food and used as a source of energy. Dogs love to play with their owners, and they need energy to do so! Nutrients are essential for an animal's growth, and can be considered maintenance tools to keep your dog in optimum health. Just as your car requires gasoline (and other types of maintenance) to run, your dog needs food to keep them going too.

There are different classes of nutrients that your dog needs in their diet: proteins, fats, carbohydrates, vitamins, minerals, and water. Choosing a balanced food that includes those nutrients is what will help young dogs grow and older dogs stay healthy.

Newborn Puppies

When dogs are first born and for the next several weeks, their complete nutrition comes from their mother's milk. However, if the mother is ill or dogs are orphaned, a commercial milk replacement will need to be given to the young pups. Your veterinarian can educate you on how to choose a replacement, as well as how to feed newborn puppies who do not get milk from their mother.

Eventually, they'll begin to wean from their mother's milk—or a replacement liquid—and begin to digest solids. To begin the weaning process, start removing the mother from their litter for short periods of time. While the mother is away, introduce them to puppy food in a dish. Gradually increase the amount of time the litter is exposed to their own food, be encouraging, but do not force the food on them.

Young Puppies

Once puppies are weaned, they'll get all of their nutrition from dog food, so be sure to choose something that's not only tasty, but healthy too. Puppies require and expend a lot of energy, so young dog nutritional requirements include increased protein to support healthy growth. Also, puppies may require three to four smaller meals a day to start and then slowly be transitioned to two larger meals per day. Talk to your vet about the best feeding regimen for your puppy to ensure they are getting their adequate daily nutrition.

Expect puppies to play with their food at first. While eating may start as a game, young dogs will enjoy the taste, and look forward to the flavors and sensations of chewing. It may help to slightly moisten dry food to get your dog comfortable chewing.

Adult Dogs

For most dogs, they reach their adult life stage around their first year, so it is important to transition to an adult dog food at that time. An adult dog's food is based on size and activity level. If you have any questions as to how much you should be feeding your dog, it's best to check with your vet, but never overfeed your furry friend. At this stage of life, dogs require nutrition for maintenance. So, an extremely active pet would have different nutritional needs from a less active lap dog. Also, a large dog requires more food in their diet than a small breed needs to ingest.  Once you've chosen the type of food that's the best fit for your dog, remember that other elements, such as temperature, will influence changes in your dog's diet. Extreme heat and cold will burn more of your dog's energy, and they’ll need to make up for that in their diet. Also, an activity change, such as starting an exercise regimen, will change the amount or type of food you offer your pet.

Because adult dogs don't need the same nutrients to help them grow that puppies do, the best dog food for your adult dog is one that is specially formulated for their adult needs. For instance, Hill's Science Diet products are specifically formulated to meet the needs of an active adult dog. Continuing to feed your adult dog puppy food once they’ve reached their full size can lead to weight issues, as puppy food tends to be rich in growth-based nutrients.
