Gradually decrease the amount of the current dog food while increasing the amount of new dog food. Continue to do this over a 7-day period. Transitioning slowly can result in fewer digestive issues and better acceptance of the new dog food. For dogs who are finicky, older, or have health conditions, the transition time could take 10 days or slightly longer.
