The food that you give your dog is very important with regard to its health and development.

 It is crucial that you understand which food is best for your canine companion before making a decision. This will help to ensure a long and healthy life for them.

Nutritional Requirements: Adult Dogs vs. Puppies

The fact is that puppies and adult dogs have different nutritional requirements. A dog that is still very young and developing needs tons of different nutrients that aren’t as important for adults.

Giving a little puppy adult food on a regular basis will almost certainly stunt its development, which is the last thing you want. A nutrient deficiency in a young dog can lead to all sorts of health problems.

There is a very good reason that adult and puppy foods exist separately. Each of these types of foods has different ingredients to match the nutritional requirements of dogs at different life stages.

Puppies need tons of protein in their daily diet, which includes a wide range of amino acids like arginine, histidine, and leucine. These amino acids help your puppy to grow into strong and healthy adults. While adult dogs also require protein in their diet, they don’t need nearly as much as puppies.

Puppy food also has a lot more calories in it than adult food, and for a very good reason. Young dogs that are still growing need the extra calories to develop normally. Giving an adult dog puppy food each day will inevitably lead to unhealthy weight gain.

Feeding by Age

1. From 6 to 12 Weeks Old

When your puppy is six to twelve weeks old, it is important that you give it actual puppy food. Make sure that the food you give your dog is formulated for this age group. There are certain nutrients your young puppy needs at this stage of life that it cannot get from adult food.

2. From 3 to 6 Months Old

When your puppy is three to six months old, you’ll want to continue giving them puppy food three to four times each day. If their body hasn’t started evening out yet, you’ll want to keep the portions small for each meal.

3. From 6 to 12 Months Old

If your puppy is anywhere from 6 to 12 months old, you’ll want to transition them to adult food. If you have a small dog, you can start at around 7 months old. Larger dogs should be given adult food only when they have reached one year old.

4. One Year Old and Beyond

After your dog turns one year old, you can start giving them half the amount you were before for each meal, two times daily.

1. When can a Dog Start Eating Adult food?

As we mentioned above, the age at which a dog can begin eating adult food varies depending on the breed. A majority of dogs can be put on an adult diet by the time they are 18 months old.

2. Take it Slow

It is also important that you transition your dog from adult to puppy food slowly. This will ensure that your dog adjusts to its new food without any issues. You should keep about ten percent of their old food in the bowl for the first few days. This is the best way to transition your puppy to their new food.

The fact is that some dogs take to their new adult food faster than others. You might have to keep some of their old food in the bowl for up to a week. If they still don’t want to eat it, you can always try giving them a different kind of adult food.

What to Look for in Dog Food
