To use this Purina Pro Plan canned dog food, simply open the can and serve it to your adult dog at mealtime. You can feed it directly or mix it with dry dog food for added variety. Make sure to provide fresh water for your dog at all times. Store any unused portion in the refrigerator and use it within a couple of days. Check the expiration date on the can before feeding. If your dog has any specific health conditions, it's a good idea to consult your vet before making any changes to their diet.
