How to Switch from Puppy to Adult Dog Food
When switching your puppy to an adult dog food, it’s best to make the transition gradually, over a 7-10 day period, to avoid digestive upset. Here’s what the nutrition experts at Purina® Beyond recommend:
1. Start by introducing the adult dog food in small amounts during the first two days, still primarily feeding the puppy food. Measure the amount of new food that you're adding and make sure to remove an equal amount of the puppy food. (For example if you’re adding 1/8 of a cup, remove 1/8 of a cup.)
2. During days 3-5, add a little bit more of the new adult dog food each day, while continuing to remove the equivalent amount of the puppy food. By the end of this period, the amount of the two foods should be about equal.
3. During days 6-7, continue adding more adult dog food, and removing an equal amount of the puppy food. By now the new adult dog food should be the majority of your dog's meal.
4. During days 7-10, continue increasing the amount of the adult dog food and decreasing the puppy food until you are feeding the new dog food exclusively.
According to the experts at Beyond, the transition from puppy to adult dog food generally happens when dogs are about a year old. The exceptions to this are large and giant breed dogs. These breeds are usually considered puppies until age two, and have different nutritional requirements based on their extended growth period. Your veterinarian can advise you on the best time for your dog to make this transition.
