Prevention is better than cure. Therefore it's best to always store your fig newton out of dogs’ reach.  You can safely store them in a closed refrigerator or place them on high shelves. Moreover, you can ensure that dogs are attended to and that the kitchen is locked when they are outdoors. Otherwise, train your dogs on the 'stop it’ and ‘leave it’ commands. It is helpful, especially when the dog snatches them away or picks the dropped fig newtons.
