A commonly asked question is whether you should feed adult food for puppies.

The short answer is no. You should avoid giving adult food to puppies, particularly in the long-term.

Puppies grow rapidly and require different amounts and types of nutrients compared to an adult dog. During the first year of life, a puppy goes through many stages, developing their bones, muscles, organs, and skeletal system. Ultimately it could be detrimental to their health.

But let’s look at that in a little more detail:

Why You Should Avoid Adult Food For Puppies

  • Adult food is larger than puppy food, making it easier to choke on.
  • Being generally harder, adult food is more difficult to chew, which can cause dental issues.
  • Lower calories make it more difficult for puppies to regulate their body temperature.
  • Large-breed puppies who get too much calcium can develop bone disease.
  • Stunted development from eating adult food leads to long-term health problems.
  • Adult food has a lower average percentage of protein (18%); puppies require about 22.5%.
  • Puppies cannot digest adult food properly – meaning fewer nutrients will be absorbed.
  • Higher Omega 3 found in puppy food promotes eye development.

When do I know it’s time to switch my puppy to adult food?

If you have decided not to go with ‘All Stages of Life’ dog food, you will need to switch your puppy to adult food eventually. Here are a few indications it’s time to change:
