Is your pooch growing but still loves puppy food? Do you satisfy his urges to keep him happy?

Or maybe you have more than one dog at different ages. If so, then dinner time must be hectic. Some owners just buy puppy food, regardless of how old their dogs are.

If this is the case, then why do companies offer dog foods for different age groups? This got us thinking: can adult dogs eat puppy food? Wouldn’t it make mealtimes effortless and hassle-free?

If only it were that easy. Read on for more.

Can Adult Dogs Eat Puppy Food?

Yes, they can. Still, it shouldn’t be the main meal for an adult dog. Food made for puppies doesn’t contain the right amount of minerals and vitamins needed by adult dogs.

So, what’s the best thing you can do if your fully grown pooch insists on eating puppy food? The easiest way to transition from puppy food to adult food is to incorporate adult food into daily meals. After about two weeks, you should fully wean your adult dog off puppy food for good.

Adult dog food provides your pooch the appropriate nourishment for his age. You’ll also notice an improvement in their digestion, as well as their overall health.

Puppy Food vs. Adult Dog Food

Puppy food is made to provide young pups with high levels of protein, fat, calcium, and calories.

Now, imagine an adult canine eating this same diet.

Grown dogs need these nutrients to maintain healthy development, but they need them in much fewer quantities.

Here’s a quick comparison of some of the main nutrients in puppy and adult dog foods.


Puppy foods contain almost 30% protein, compared with an average of 18% in adult dog foods. Protein supplies pups with ideal levels of energy to grow and develop at a healthy rate.

As for adult canines, protein helps with cell repair and muscle maintenance. So, they don’t need it in high amounts compared with younger pups.


Puppy food has an average fat percentage of over 20%. In contrast, adult dog foods can contain an average of 15%. Pups rely on fat to stay warm. It also boosts their energy and growth levels.

However, when adult pooches eat high amounts of fat, it gets stored as excess weight. Over time, this can lead to chronic diseases, such as arthritis, diabetes, and heart disease.


Calcium is necessary to support a puppy’s growing bones. This is why puppy food contains so much of it.

On the flip side, when adult dogs consume too much calcium, it can cause bone-related health issues. They may show signs of rickets-like symptoms, like joint swelling, difficulty walking, and bone pain.

A Final Note

Can adult dogs eat puppy food? Yes, it’s safe and healthy, provided they eat it in moderation.

The problem is that it’s not a suitable diet for adult canines. Puppy food contains more nutrients than the average adult pooch requires.

To prevent food-related health problems, switch to adult dog foods. These foods are specifically designed to meet the demands of a fully grown canine.
