Arrange the following steps in the correct order to create a sound food guarding plan:

installment feeding: trainer approaches empty bowl and adds a handful
installment feeding with overlap: trainer approaches with the next handful while the dog still has a bit of food remaining from the previous installment
bonus addition: trainer approaches mid-meal (dog is not warmed up) and adds a bonus to the bowl (something tastier than what is in the bowl)
bowl removal: trainer approaches mid-meal (dog is not warmed up), picks up the bowl, adds a bonus (something tastier than what is in the bowl) and returns the bowl to the dog
