Feeding Guidelines Serve as is or rehydrate by adding warm water. If your dog does not drink plenty of water at mealtime, we recommend rehydrating. To rehydrate, crumble and add 1/4 cup of water for every two patties. When feeding dry, always make sure your dog drinks ample fresh water at mealtime. Optimal feeding amounts may vary with age, size, breed, and activity level. Please refer to the feeding chart below as an initial recommendation and adjust food amount as needed to reach desired weight goal.
