Your pup is growing fast. Too fast, you may say.

With every new stage comes a whole new set of challenges. They’ve gone from cute puppy to temperamental teenage dog. Now, they’re on the cusp of adulthood, and you’re navigating through it. You’re searching for a conscious and careful way to go about switching dog food now they’re almost grown but are unsure how.

You’re also careful about their diet. You want to give them wholesome and balanced meals, perhaps considering vegan dog food. Or, if you’re already feeding them vegan dog food for puppies, you want to continue their lifestyle as an adult dog.

Make sure their diet suits their maturity level and nutritional needs, otherwise they may suffer from digestive issues, malnutrition, or obesity. Here’s our guide with key steps to follow and recognize the stages when switching dog food.

What’s the Difference Between Puppy and Adult Dog Food?

Puppies need plenty of energy to grow and develop. This is why the caloric density of foods designed for adults and puppies differ. Puppies need more calories than adult dogs, even if they are of a similar size.

Your puppy may lack the nutrition they need if they eat food designed for adults. Their bodies require plenty of nutrients to develop tissues, muscles, organs, and bones to reach their adult size.

Some adult dogs, on the other hand, can thrive on the higher concentrations of fat, protein, and other nutrients in food designed for puppies. These dogs include athletic, pregnant, or lactating individuals.

However, switching dog food is often advisable when the time is right. Otherwise, you’ll have a flabby Fido on your hands!

When Do You Switch to Adult Dog Food?

How do you know when the time is right for switching to dog food for adults? Consider their breed, age, and size. Different dogs mature at different time periods. A good telltale sign is that when puppies have reached around 80% of their expected adult size, they can be switched to adult dog food.

Keep in mind, the smaller the breed, the faster they will mature. Although if you own a mixed-breed pup, then you may have to talk to your vet or breeder to determine how large they will grow when they become adults.

Here’s a basic guide to help you determine when you can consider your puppy as a grown up.

If your puppy is a small breed (e.g., Chihuahuas, Yorkshire Terriers, and Miniature Pinschers), they usually meet maturity at approximately 9 or 12 months of age.

If your puppy is a medium-sized breed (e.g., Cocker Spaniel, Beagle, Bull Terriers), they should keep eating puppy food until they are around 12 to 14 months old.

Giant breeds (Mastiffs, Great Danes, St. Bernards), on the other hand, should continue eating puppy food until they are 12-16 months old.

How Do You Switch to Adult Dog Food?


Switching to adult dog food and sitting at the adult table means no more three square meals a day for the pup!

As a growing puppy, they have more energy and higher metabolism, so they used to need to eat three times daily. However, when you begin switching dog food for adult dogs, you’ll begin cutting back on calorie-rich, protein-dense food, as well as on the number of meals.

Most pet moms and dads feed two half-portions of adult food once their dogs hit over a year old.

Don’t forget to keep your eyes on your furry friend’s body, not his bowl. The issue isn’t whether they’ve eaten all of their food. The nutritional needs of dogs differ individually, each having different metabolism and body types.

Observe whether they begin skipping meals or seem less hungry. That might mean they’re ready to switch from puppy food to an adult diet. The higher calories contained in puppy food are probably making him feel more full. However, if you’ve already switched to adult dog food and they’re still not devouring all of their meals, it could simply mean they need fewer servings per day or less amount of food for each meal.

The secret to switching dog food, from puppy to adult formula, is to do it slowly. Mix in a tiny amount of the adult dog food with your puppy’s current formula. Later, you want to gradually increase the amount over the span of a week, while lessening the puppy food.

By the end of seven days, you should be only feeding them adult dog food. An incremental switch will decrease the likelihood of them experiencing any digestive issues.

Check out a handy guide to the portions for switching slowly below:

Portion Sizes for Switching from Puppy to Adult Dog Food

Day Puppy Formula Adult Formula
1-2 3/4 1/4
3-4 1/2 1/2
5-6 1/4 3/4
7 0 4/4

According to the table, for the first couple of days transitioning food, you combine a quarter of the adult dog food with three-quarters of puppy formula.

On the third and fourth days, you combine half of the adult formula with half of the puppy formula.

On day five and six, you combine three-quarters of the adult dog food with one-quarter of the puppy formula.

On the seventh and last day of transition, you’ve completed the process and can give your dog 100% adult dog food.
