Here are some general factors that will influence the decision:
* Breed: Large breed dogs generally require puppy food for a longer period than smaller breeds.
* Size: Larger puppies will transition later than smaller puppies.
* Health: Some puppies may have specific dietary needs due to health conditions.
* Age: Most puppies transition to adult food between 12 and 18 months of age.
Switching too early can lead to nutritional deficiencies, while switching too late can lead to weight gain and other health problems.
Remember, your veterinarian is your best resource for personalized guidance on your puppy's diet.
