when should you switch puppy to adult food
How to Switch from Puppy to Adult Dog Food. When your puppyâs growth in height slows, you should begin switching to a premium adult-formula dog food. This usually occurs around 9 to 12 months for small breeds, around 12 months for medium breeds, and around 12 to 24 months for large breeds. A gradual switch over a period of four days helps minimize intestinal upset. This same gradual switching of formulas should be done any time you change your dog's type of food.
