Doctors Foster & Smith offer the following vital information about introducing a new, healthy dog food diet to your pet: Normal bacteria in the intestine help your dog or cat digest food. A sudden change in food can result in changes to the number and type of bacteria and their ability to help digest food. These changes can lead to intestinal upset. Therefore, your pet must be switched to a new healthy dog food slowly. We recommend switching to a new food gradually over the course of 2 weeks. For example, make a mixture that contains 10% of the new food and 90% of the old food and feed that for three to four days. www.critterschoice.com
