Thank you for contacting Doctors Foster and Smith with your concern.
Either the Doctors Foster and Smith Chicken and Brown Rice Adult Dog Food or the Doctors Foster and Smith Lamb and Brown Rice Adult Dog Food would be great choices for your active, large breed dog. Both formulas are balanced to meet the nutritional needs of large breed dogs per AAFCO (Association of American Feed Control Officials) guidelines. These diets contain high quality protein, fruits, and vegetables to provide the essential vitamins, minerals, and antioxidants needed to support overall health. These formulations do not contain any artificial colors, flavors, or preservatives.
We recommend discussing any diet change with your veterinarian prior to making the switch. If you do switch diets, be sure to gradually introduce the new diet over 7-14 days. An abrupt change in diet often results in gastrointestinal upset in dogs. Once the transition has been completed, use the feeding guideline chart to determine the correct amount of food to feed to your pet. The amount fed can be adjusted based upon each animal’s unique needs (activity level, etc.).
We hope this information is helpful. Thanks again for contacting us.
