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